Very happy to see coffee making an appearance on your channel, and especially delighted to hear about your increasing (and quite correct) obsession with great coffee…
Ooo hi James 👋
am I the only one that was waiting for James to comment?
@@jonahbrauer7387 nope
Ngl I just saw the title in my subs feed and assumed this was one of your videos, turns out you’re here, just not in the way I expected.
Very happy to see my favorite coffee RUclipsr (and the person who helped turn me into a coffee obsessive) commenting on one of my favorite cooking channels.
"I'm a fan of Light Roasts, for reasons we will get to."
My mind: "It's the acidity"
HOLY HOLY!!! I can proudly say that I have the two HOTTEST women on this planet as MY GIRLFRIENDS! I am the unprettiest RUclipsr ever, but they love me for what's inside! Thanks for listening mark
@@AxxLAfriku wtf
@@AxxLAfriku When have you started tainting the replies on this channel
I'm shocked axxl hasn't been banned yet
@@technetium9653 it's because nobody cares about him, because he is a sad, pathetic human being
I really appreciate when you don't hide sponsorships and manage to make an interesting video out of it. Cheers!
I don't think he ever hid a sponsor, it's just that this time his sponsor paid for a full video instead of a couple clips
It's illegal for RUclipsrs to hide sponsorships
@@ullschwitzjib3612 I didn't say he ever hid sponsors. I'm saying I appreciate when he just makes a full video out of them.
From the company’s perspective it is much better to be getting on a cooking channel compared to a coffee channel. For one, cooking channels have a wider audience base (eg Adam has almost twice the subscribers of James Hoffman), and more of these people don’t already have well formed opinions and preferences.
@@bretwilliams249 by saying "I appreciate when you don't hide sponsors" it automatically implies that he sometimes does hide sponsors.
It's like if a cereal box said "Now asbestos free!" - that would be extremely weird and suspicious because it implies it wasn't always asbestos free, lol
I WAS THERE!
Adam, great to meet you very briefly the day you filmed at alma. (I had the puppy) blew my mind when I walked in and you were there filming! I went total fan guy mode. I'm honored know Harry, Leticia, and the crew well. Trade Coffee really knows what's up if they chose Alma to be featured.
great video!
can you put a time code?
Of course it’s not the roast that determines how much energy you get out of it.....
*It’s how much you drink.*
ok
But roasting makes the beans hot, which means they're storing more energy.
@@nowdefunctchannel6874 but they’re cold by the time you get them, if that’s the case then people would eat hotter food to get more energy, although you’re right by cooking means storing energy. It cools
@@bonbin6053 my comment wasn't supposed to be serious
@@nowdefunctchannel6874 yeah they took it a little too literal. I thought it was funny though if that counts.
Interviewing your sponsor for a video is next level
Peak youtube.
This is how you make an ad interesting
Technically they aren't the sponsor. Trade coffee is the middleman between the customer and the suppliers. He interviewed the suppliers Trade Coffee set him up with.
and we are the idiots watching the commercial.
I'd like to understand how this was made possible. Adam paid a local Georgia crew to go to Alma and record his questions? Pretty cool stuff.
Great video! Just one scientific note: Caffeine is one of the most stable compounds in nature. It does not degrade at the temperatures used in roasting. It sublimates at 178ºC at atmospheric pressure. However, at the high pressures within the beans during roasting (up to 6 atm), it does not sublimate. As the temperature increases, part of the caffeine is lost to the exhaust gas as it is dragged by the water vapor coming out of the beans. Caffeine is only moderately soluble in water at ambient temperature but its solubility increases to infinity as the temperature is increased to 100ºC. In the 1940s, the caffeine used in Coca-Cola formulation was extracted from the stuff scraped from the coffee roasters exhaust pipes.
This deserves more likes! Fascinating note about the process
After a cereal video not sponsored by magic spoon, its great to have a coffee video sponsored by trade
I'm really glad I got sponsorblock, I just KNEW this was going to have the same trade ad I see everywhere.
Yes I love brand
100% soy comment
I can attest to the ethics of trade. When the coffee company I worked for fired all of its employees for unionizing and it became clear that they had done so illegally, trade, their biggest contract, pulled them from circulation. It was a big deal for us trying to get some sort of communication from the owners.
It was called Augie’s coffee btw
I heard all about Augie’s since I’m from the IE and I’m in the coffee community. We were all glad when they got shut down bc of their practices!
“you can be confident that your beans are ethically sourced...they have to sign a pledge” ahh just like how teenagers did to avoid drugs since 5th grade lol
We super duper promise we won't use slave labor. Trust us.
90s teachers told me people would constantly offer me free drugs and alcohol. Well where fuck are my free drugs?! Lyin ass teachers
I dont even have to look into it, I am 100% confident the coffee beans alma uses have are all from slave labour lmaoo who wants to bet Leticia is no fan of Zelaya or Arellano
@@ambrospike2 People who are super anti-drugs never seem to realize that alcohol is a drug, and so is caffeine. Somehow it's ok to be an alcoholic but if you like edibles you're a drug addled stoner. And like 80% of our society relies on mass consumption of a stimulant drug, caffeine, to even function or make it through the day. The fucking irony.
Yeah, that picture of Letitia's dad in fatigues next to a "so-and-so batallion" sign does not inspire a lot of confidence. The military in Latin American countries can be very shady
idk why but when pumped up kicks randomly started playing at the end I laughed.
Didn't even hear that until i rewatched the end.
same
When?
Edit: Nvm-just rewatched it-lol
At what time? I can't find it
@@Stormrunner when she was talking at the end. It’s really quiet
“I only recently became a coffee obsessive.”
Welcome to the dark side, Adam.
badum-tss
Come to the light side of the roast, we have acidity.
long live the empire
"If you only knew the POWER of the dark side!"
I prefer the full city side
growing up with only public television loaded with mostly infomercials really groomed me into watching stuff like this
Do you want your coffee rare or well done?
Medium-well.
I hate acidic coffee so I wanna be away from the light end while bitter is ok but not desired so I go towards the well done side of medium.
Roasted to the point where it is indistinguishable from the dirt in which the coffee plants were grown in. It needs to be so bitter that your body physically rejects it.
I like my coffee done well.
I love fruity coffee. Especially fruity espresso, you can really taste the beans uniqueness
Extra rare. Yellowish brown.
5:58
There's this brand of instant Vietnamese coffee I used to buy and people thought i was having a stroke because to me it had an aftertaste of popcorn. I'm glad to know I wasn't crazy after all these years
i know everyone talks about the smooth sponsor transitions, but this time, i genuinely am not sure where the line is between the video and the sponsor.
The whole video is an ad. Haha
He literally says in the first 10 seconds that this is a sponsored video. Pay attention or don't comment.
@@Thuazabi chill out
@@Thuazabi “Pay attention or don’t comment” 🤓
"walk on home boy"
*Pantera intensifies*
🤘
I caught that too
“i know that im liking lighter roasts lately”
more *acidic* & expressive of the coffee’s original flavors
i see
First crack is the best crack.
The guy must drink two liters of vinegar per day. Never seen people put so much vinegar and wine on everything, jesus.
I'm impressed he's not drinking that ancient roman drink Posca every day.
I think you’re the only one here that can make an entire video a commercial and still be entertaining and informative. Cheers.
Adam your hunger for new knowledge, and tenacious personality makes you one of my favorite RUclips producers. You're more than just a chef, you're an educator. Glad I found your channel a couple years back. Excellent work!
🍶🍗👉
It's crazy how even his ad videos are really well made and interesting, great job all around and one of my favorite channels and youtubers
Fun fact: while lighter roasts do indeed preserve more of the polyphenols found in the green bean, they (counterintuitively) also have higher levels of the carcinogenic acrylamides that are formed in non-wet heating processes above 120° Celsius. There is a massive drop in the amount of acrylamides from light to medium roasts, and another drop (albeit smaller) from medium to dark. This is counterintuitive as, normally, longer (dry) heating durations and/or higher temperatures lead to continuous increases in acrylamides (think going from golden to dark brown to black in bread and potato products, golden being a lot healthier for you). If anyone is interested, I can put some links to the studies showing this.
Cool info. Thnx for sharing.
9:16
i did a double take when i heard the music in the background lol
great video though, i actually never knew what made light roasts and dark roasts so different
Thank you for pointing out the time stamp
Ah I didn't hear it at first. Is that Pumped Up Kicks?
@@kindlin yes
You should really do a collab with James Hoffman. You two are my favourite youtubers of this quarantine!
As usual you have made a very informative video. I also appreciate the way that you weave your spiel for your sponsors into your stories, there is a level of honesty and frankness in your "I'm advertising here" that I find lacking in many other RUclipsrs.
I went to high school about a half-mile from a medium-scale coffee producer in Maine, so I can tell you for sure that coffee roasting doesn't always smell pleasant
"there's no competition because the farmer and the chef are married" Adam, are you sure that you're married?
the way you work your sponsor into the video really is magical. I know its an ad but I really do enjoy watching at the same time!
God man your video production level is getting so good! You put together media better than what TV networks are capable of!
I think he used to be a journalism professor, so it makes sense 😎
adam doing coffee stuff is like my two worlds combining in one video.
I know it’s an ad, but still spreading coffee knowledge. I love it :)
Like the knowledge that basically all coffee, including the one that gets to wear the "fair trade" label, is produced through what is basically brutal slave labour and is tied to a century old history of US-backed fascism and corporatism is Latin America?
@@jojomojo508 I’m polish (Slavic) so go bark your first world problems at someone else... thank you.
@@losbigoslocos US-backed fascist coups and genocides as well as the murder of trade unionists in Latin America is a first world problem? I mean, it is a problem caused *by* the first world, so I guess you are right in a way.
Didn't even realize until the end that this video was basically a 10-minute ad
Adam is just too clean with it
I spotted that right away.
He literally opens by saying "this is a sponsored video for Trade Coffee".
I often wonder what type of people sponsored videos and ads work on. Now I know.
Then you weren't paying attention and shouldn't be commenting.
This is the kind of sponsored content I love to see!
How soy can you get? You shouldnt like seeing ANY sponsored content. Why would someone be happy at corporations and private companies deciding what you get to see?
@@jojomojo508 i don’t have a problem with sponsored content like this because I get to support the youtubers I want to support by watching it. You know they don’t work for free right…
Yeah, I'm willing to watch an ad if the ad is also content.
@@jojomojo508 That corporation is paying so I can watch Adam's videos for free, and I'm okay with that
@@luigig44 You watched an ad for free. Good job.
btw Alma has a ton of weird ass ties to cops, the US military and fortune 500.
I find my distinction between dark vs light is if I want something comforting (dark roasts that are familiar to my taste buds) or exploratory (lighter roasts that will challenge my taste buds). Time of day matters, why I'm drinking it (caffeine bump for work or to really savor it) matters, what I'm drinking it with (deserts almost always go with dark roasts for me because the increased bitterness can be a great compliment) matters.
If we have to have ads I wish they were all like this, entertaining and with interesting things to learn
That's one thing I love about his videos, he makes even the sponsored content part of the overall conversation.
Yeah, seriously. If all ad's were this interesting I would watch them and use the john during the regular program :)
Alma is in Georgia, so it’s pretty neat that Adam featured a local specialty roaster. I picked up a bag the other week from Alma. Really good coffee!
Adam unscheduled upload? I’m down every day.
there's usually a schedule? What is it?
@@DukeBG Recipes thursday, other vids monday
@@DukeBG recipes on thursdays, other stuff on mondays.
I said to my friend "man I can't stop drinking coffee" and he told me "you look like Dave Grohl from the Foo Fighters" and well it didn't fix my problem but I found my new favorite band
One of my favorite channels. Thanks for your perspective Adam!
Only Adam could make a 9 minute ad that I would watch all the way through
He always has been great with working the ad into the video content.
Here, he takes that to a whole new level!
Extra Credits made a four-part history of the Second Punic War that was explicitly an advertisement for Total War: Rome II. There's a right way to do sponsored content.
I figured I'd have the *GROUNDS* for a couple coffee bean puns..
But I'd probably get *ROASTED.*
Good job.
"I like light roasts for reasons we'll get into later."
Me: *sees "more acidic" as a descriptor* I think we all know those reasons, Adam. :DDDD
This is a great video. Very informative. Also, your sponsorships are probably the best on RUclips.
I don’t go to sponsors. Ever. But your honesty in the video and apparent sincerity have made me go there! Thanks for being honest.
Man I used to think that dark roasts where were its at and then I had a light roast pour over for the first time maybe 5 years ago and I never looked back. Sometimes I'll do a medium roast but I just love the caffeine punch and acidity of a light roast.
Very informative as always. I can finally talk to my parents about coffee using the knowledge I've learned from this video and act like a high-and-mighty adult who knows their stuff.
Great video and visuals with the different stages of roasting. My dad started roasting his own coffee with a DIY build and no matter how much he explained it I never understood the different roasting stages. Now I do!
You keep finding amazing and underappreciated craftsmen and entrepreneurs for your videos
I have been using trade for a while it's a great way to check out all these unique roasters across the nation.
I like to use white wine rather than water for making coffee
Use vodka
Why I roast my cup, and not my coffee
As I was growing up in Jacksonville Florida downtown their was a roasting facility for Coffee and I remember the smell that we would get as we crossed the bridge to go over into town, how wonderful the smell is of roasting coffee.
I would love more coffee content like this! Its very accurate and I'm curious to see how you would approach other things (espresso, etc)
I wish Ragusea had addressed brew techniques and temperatures for the types of roasts... maybe recommendations by the roaster... techniques and temps do affect taste
I wish Adam has addressed the long history of slave labour and US-backed fascist coups that are inherently tied with growing and harvesting coffee and how fair-trade type labels, at best, mean nothing, and at worse are just a way to scam gullible foreigners and make the owners of fair-trade companies richer, and not the actual workers.
So what Adam is saying is that he prefers his coffee rare, but you do you.
this is perfectly timed with my newly found interest in coffee! Thank you Adam
Great stuff Adam, thanks.
Bro it is 2 am in India but I am goona watch your video before going to bed 🙂
I am in India too & it's 10 mins to 2 am rn
I’m mexican
Ethically sourced? Okay sounds good! "All roasters have to sign a pledge that they are ethically sourced" oh...okay so they arnt then
"Roasting is like any other kind of cooking:
The more an ingredient is cooked, the more you're tasting the work of the chef.
The less it's cooked, the more you're tasting the work of the farmer."
Great production job, Adam; great footage, great script, great delivery. Did you do the whole gig? When I was in production in the 90s, we would have had a team of at last four people involved in making something this nice. Your broadcast experience really shows.
This comment Is just a suggestion for Adam. In the snow cone video he said he didn't like eating pomegranates and I will admit its hard but I learned this amazing technique where you cut kind of along the rib protrusions that kind of stick out (there are usually 5 or 6 for the ones I get). So now you can spend like 20 or 30 minutes pealing out the seed clumps individually (I find using the sides of your thumb helps) but the much faster method is to hit the skin part with a spoon until the seeds fall out. And this is the part I found most suprising you can eat the seeds, they are actually good for you and they don't really taste like much (unless you juice them, juicing them kind of dissolves some bitter flavors I suspect are from the seed) not to mention they add alot of textural contrast to something like plane yogurt, that's one of my favorite things to eat w/ pomegranate
This one feels more like an infomercial than a normal video, i.e. there would be no video if the sponsor didn't ask Adam to make it.
That is generally the case for Saturday videos. They are "bonus" videos. If you don't like that sort of content, feel free to skip the Saturday videos.
That's because it is
Yeah, I didn't find it that interesting and so much of it was about a companies policies which is quite boring.
@@themikeroberts Also the fact that the company has many ties with the US military, does pro-cop propaganda in the midst of the BLM protests and criticisms of police brutality, and also has a weird history of land-owning in Honduras around the time of the fascist coup but I digress
@@jojomojo508 I'm curious now after seeing your other hundreds of replies. What do you consider "Pro-cop propaganda"
These topics are so interesting. There's a whole world of coffee mechanics I didn't even know about
Great Video! Thanks for the info. I’m good friends with the Finca T family. Al is the real deal. Great to see that family highlighted! Their passion is contagious. Harry is such a great guy. Thanks again.
What a wonderful company Alma is, with a lot of knowledge and passion for coffee! Great to put such amazing people in the spotlight
Not sure if "walk on home, boy" was meant as a PanterA reference because it sure didn't have that attitude Haha
I took it as Pantera reference.
People around the world should be able to trade directly. The people doing the labor should be able to prosper from their efforts
Excellent information, I enjoyed that thoroughly. Thank you.
While I can't drink coffee, this very much reminds me of the discussion happening around roasting in chocolate! I'm so glad to see more transparency happening down to the techniques, because there's so much to geek out here. (Though unlike Adam, I sadly can't be converted to coffee - I'm sensitive to even the smell. But I do think the folks working in direct and transparent trade coffee and chocolate are most awesome folks!)
The cool thing about coffee and chocolate is that both are grown, harvested and processed through slave labour, child labour, and have a long history intertwined with US-backed fascist coups against left-wing democratically elected presidents. What even cooler is how "fair-trade" type labels, just like "dolphin-safe" or "sustainable" labels are all but meaningless and often an outright lie.
@@jojomojo508 And that's why I like transparent and direct trade! Because you're right, there's a lot hidden behind the labels at this point, especially with the rise of greenwashing. And we still have a long ways to go in fully removing child slavery and child labor in cacao. In craft chocolate there are now two main ways to source cacao: through the farm directly or through coops like Uncommon Cacao, Meridian Cacao, and GoGround. (And what's really neat is you, right now, can buy beans from Meridian and Uncommon! I hope GoGround does as well soon, but not yet.) These folks are child labor and slavery free (thanks to paying their workers way more), you can access their transparency reports, and even talk to the brokers (and sometimes farmers) in person if you go to chocolate festivals. It's grown so much in the last ~10 years in cacao, and I'm super excited to see more like it happen.
@@DessertGeek I'm sorry but, at best, all those NGOs and orgs just give a bigger cut to the owner of the farm, while the people actually harvesting the cacao and the coffee still see almost none of the revenue created by their labour. It's weird to me that you are aware of greenwashing but then believe hook like and sinker in feel-good neoliberal propaganda.
@@jojomojo508 So wait, I think we’re talking from different references? Because these are mostly single family farms with no employees running co-operatives. So yes, with Meridian and Uncommon and GoGround more money goes straight to the individual growers and that’s pretty awesome! I highly recommend checking out their reports when you can!
9:15 I'm happy to see that these farmers also have an amazing taste in music
These people aren't farmers. They own the farm, but they aren't farmers. They are owners and landlords. The kind of people who would back fascist coups in Latin American against left-wing elected officials who tried to redistribute land to tenant farmers and the people who actually farmed the land.
@@jojomojo508 ...Okay? I was just trying to say I like the song they had playing in the background; there's no need to break out land ownership, Fascism and Latin America on me lol
"walk on home boy"- You are among the many people who have used that lyric outside of its original context and I am here for it. Anuddah great vid, man.
Joined Trade Coffee when he first talked about them, and I'm onto my 4th bag. It's was pretty fun to try a light-medium-dark roast and compare the taste profiles. I think I'm definitely a medium roast kinda guy BUT still going to let them send me their recommended roasts! Thanks Adam for helping me find out about such an interesting service!
I'd love to see a similar video for tea. Enjoyed the video thoroughly, and I'm also tired of people asserting that I can't handle "real coffee" because I drink light roasts
I only say that to people who drink there coffee with cream or milk. Adding milk or cream changes the taste of the coffee. So it must mean you don’t like the taste of the coffee.
Hey Adam! Thanks for the another dose of entertaining content and I'd like to share a video suggestion. You've already made some Indian food recipes pretty long time ago and I'd like to see the sequels. Especially I think the curry topic would be interesting, basically why there is Indian and Japanese versions of curry and how would you adapt them for home cooking. This could serve both as Monday and Thursday types of videos. Hope you have this idea in your future plans or if not, then I'll still see some Indian food history in the future.
I fell, or rather dove, down the rabbit hole with tea(mostly Chinese) about 2-3 years ago and I feel like it really, really has helped me to understand the basics of other drinks, like beer and coffee, more easily. I think there is a big overlap when it comes to understanding different beverages so skills can be generalized. I will probably never dive quite as deeply with coffee or beer as I have with tea, but I have managed to step up my coffee(and beer) game thanks to the confidence my basic tea knowledge has given me. Maybe some day I'll even try applying this to wine...
Great coincidence, Alma is next on my Trade sub. Looking forward to it!
Would be nice to do a one-time order without having a recurring subscription. I just want to try them out once, see if I like it, and then maybe agree to a subscription. It doesn't seem like that's an option- you only get reoccurring subscription options. I don't want to go through to rigamarole of cancelling if it's not good.
9:32 Mr. Adam Ragusea disintegrates and becomes a higher being
Thank you for your video.
Great video. Love the topic too and your style is just wonderful!
"I'm liking lighter roasts lately for reasons we'll discuss later."
*shows description of light roast that starts with acidic*
That's self-explanatory
Uhhhhh, finally something good about my country Honduras, it has the best coffee in my opinion.
I worked at an industrial coffee roasting facility that made coffee extract. There is nothing like going from green to ground in one day, grinding it and drinking it same day. The freshness and flavor is amazing, and my god you get so much more of a kick from the caffeine when it's that fresh. I got to take home gallon ziplock bags of it, and ended up giving it out as gifts. Everyone loved it. Even at artisanal coffee shops couldn't match the quality of that coffee o made at my house with the grind I brought home from the factory. Boy miss that, worst job I ever had though.
Adam
you are a blessing, thanks for another great video
This was a wonderfully informative video that really did give some nice info about the roasting process, but Adam - the level of integration of your Trade sponsorship into this video did start to distract me. It allowed me to believe the whole video was just a big ad for Trade, rather than a documentary that happened to be sponsored by a related business. I totally get that there's a line to draw here, but this felt a bit too much like an extended promo spot.
To me it felt more like an ad for Alma coffee than for Trade. My reaction to watching the video is that I wanted to look up Alma and order coffee directly from them, bypassing the middle man and sponsor of the video.
This might sound weird but can you do a video of how to properly/scientifically clean after cooking/eating? How to wash dishes, basically. Should you soak? should you rinse/drain your sponge with cold water? When should you use an iron sponge? Do you have to use soap if there's only cookie crumbs on the plate? Etc.
Ask your mother or your grandmother.
I signed up for Trade because I saw it in an earlier Adam video and was like eh why not. I have been working from home and really missed getting fancy coffee from the shop near my office in the city. It’s kind of fun, gives me something to look forward too and new things to try. I am not a huge coffee buff but it’s just a nice treat every day.
As a Guatemalan (coffee land too) I was jumping of joy about this video. Im so glad about the work Alma is doing.
Speaking of coffee, would you attempt cooking with it? There are savory and sweet recipes
Keep in mind Adam Ragùsea occasionally does videos on Saturdays, if you’re not aware.
i like how you smelled the coffee with a mask on. really makes sense
adam is the best at integrating sponsorship into the content. sneaky genius.
Thanks for your great work.
Adam Ragusea releases a new video: yay
Oh, it's about coffee. I can't stand coffee. It's just nasty bitter dishwater....
Me: It's an Adam Ragusea video, it doesn't matter, I know its going to be interesting anyway, straps in for the next 9:45
Not sending hate toward anyone here, but signing pledges doesn't do shit. Legally binding documents rarely stop companies from breaking the law.
Its like having highschoolers sign a waiver that they wont try weed
Feel free to send hate. A comment near the top has some good replies that expose these fuckers for what they are. Very shady people work in the coffee industry and there is NO guarantee any of their products are ethically sourced
Good looking out Adam. I live in Georgia and will be checking them out.
At about 9:30 in this video is one of my all time fav songs! Great vid, Adam!
