  • Hey!
    The testing I did leading up to this video consistently showed greater cups of coffee from 95 and up with lighter coffees (aromatically, balanced, etc). BUT there was always a smidgeon of astrigency. The darker the roast, the more noticeable negative attributes became at higher temperatures.

    Have you ever tested the effects of water temperature, all things held constant, in a blind tasting? It is eye-opening! Thanks again to Dr. Samo Smrke for giving me the scoop on the results of the sensory tests he has been a part of with regards to water temperature in espresso. Don't forget to smash that like and subscribe! Cheers

      You should probably re-do this without any prior knowledge, i.e. without knowing if any of these are brewed at different temperatures, can you detect any differences and if yes, then order them by preference.

      I’ve been a strong supporter of temperature not being as cut and dry as most would assume.
      I think a good follow up you should try is different temperatures at different grind settings. Especially with a expressive coffee/roast profile you can find vast differences between two cups that both taste “good”

    • @aggese
      @aggese Год назад +1

      I know that espresso at 120°c don't tast as good as when it's at a bit lower temperature,
      (I have an old ascaso pro steel that only have a 100°c temperature switch so it overshoots with up to 20-25°c, I will change the temperature switch to a 90 or 95 one as a easy fix but I plan to add proper PID control sooner or later)

  • @tommypatton3556

    I think another interesting experiment would be to dial in the same coffee (via grind size, probably) at 4 different temps, then do a side-by-side of the 4 dialed-in brews (different temps, and presumably different grind sizes) to see which favorite is your favorite.

    • @zeropuckprep
      @zeropuckprep Год назад +3

      This is pretty much what I do dialing in espresso find a good grind size that tastes good at my goto temp 80C and then start increasing the temp to see if it alters the flavor for the better. We used to buy 5 pound bags at a time and do just that, but not anymore with layered shots.

  • @HigeYatsu
    @HigeYatsu Год назад +13

    I've been playing around with low-temp brews for a long time now, and honestly I RARELY brew above 93C anymore as a result. It's a bit fussy, but when I brew larger batches (35g of coffee) out of my Stagg XF, I actually do my bloom and first pour at 92C, and then cool the water down all the way to ~59C to finish the brew. And then further sacrilege, I do full bypass and add water to the finished brew if it tastes a bit too tight to get better separation of flavors. The resulting cups tend to have more clarity and be a bit more juicy than those brewed wholly at higher temps, and the bypass honestly opens up the cups in an amazing way, it's worth trying if you haven't.
    My unscientific hypothesis is that it's not the TDS that you're targeting when it comes to water temp, but rather what compounds comprise that TDS. To me, it seems like higher temps extract different compounds than lower temps, or at least the same compounds at different ratios, so while temperature might not have a huge impact on TDS, it does have a huge impact on the taste of your brews. And once you have the compounds in the cup that you enjoy, stretching your total yield can actually have a very positive effect that doesn't make the coffee taste any less extracted.
    Happy experimenting!

      How much water do you add as a bypass in the final brew?

    • @HigeYatsu
      @HigeYatsu Год назад +3

      @@nebojsabeljanski2126 It really depends on the coffee, and on your taste preferences.
      I would say you could add an amount equivalent to stretching your brew ratio by an additional 0.5 : 1, taste, and then repeat as necessary until you land on something you like. If you have access to a scale like an Acaia that displays final brew ratios, or the patience to weigh your brew output, you'll notice that your actual brew ratio in cup is tighter than the ratio of coffee to water used to brew. For example, if I were to brew my 35g of coffee with 545g of water (roughly a 15.5 : 1 ratio), it's likely my actual yield resulted in something closer to a 13.5 :1 ratio (something like 475g of brewed coffee in my carafe). Usually the sweet spot will lie somewhere between the actual brew ratio in your carafe and the ratio you were targeting, unless your original brew ratio was off for the coffee. So in this example, I might add an additional 7.5g-30g of water in 7.5g increments. But often times I'll push it even further just to see what I get for fun, and sometimes that can lead to some pleasant surprises, and some good lessons learned about the ratios that particular coffee likes.
      Sometimes just a few grams of water make a huge difference, and other times you have to stretch your ratio a surprising amount to hit the cup you were aiming for. Hope that helps, and happy brewing!

    Hey Lance, as a follow up, I think it would be worth trying this experiment but at a lower brew ratio. If the hypothesis was initially that hotter temperatures dissolve more compounds I would imaging there is a saturation point (think of a logistic curve). It would be interesting to see how extractions change at different ratios assuming each temperature reaches saturation at different points which I guess might impact flavor.

    Thanks so much for the effort to test these things so that we can all enjoy our coffee journey. As an engineer I find so often the things we can count don't count, and the things that count can be hard to count. Other scenarios of the partial derivative "one thing at a time" approach is when the system shows high sensitivity to a combination of variables but low sensitivity to them changing in isolation. This could be a combo like temp + grind or temp + extraction time. Really fun to think about. Thanks.

  • @masika6867
    @masika6867 Год назад +1

    This is super interesting! Well done on the shorter video format - it was clean and to the point. I think what Im struggling with now is do I need to be cupping for temp for every coffee that I buy and then cup grind levels at the optimal temp to bring out the best flavors of the bag. Feels like I would go through half the bag testing permutations that would not carry over to the next bag. There’s so much fun to be had with experimenting but the downside is the amount of coffee used to experiment.

    • @RadioBuempliz
      @RadioBuempliz 5 месяцев назад

      Sour compounds need somewhat above 88° to extract, bitters need about 92°. Since they are fast dissolving they have huge impact on taste but not on TDS. What drives TDS are long chained sugars which are sweet but tasteless.
      This kind of stuff was done back in 1996 by Ted Lingle and is still valid. The basics of chemistry do not change from day to day...

    Respect for this video. It's important to find that middle-ground between research and day-to-day experience. I've lowered my brew temp a bit, to 93, and I'm happy with the results. It feels the most consistent. At 95+ I lost fruit, maybe because I'm sensitive to coffee bitterness. So maybe tuning temp to palettes makes sense.

    Thanks, I'm grateful for your approach and putting yourself out there. It must take so much courage to be authentic and honest. I'd be very curious to see a blind taste session of this same settings where you taste with your coffee brother James Hoffmann. For to my knowledge, he's also been in the camp of brewing with boiling water. (He actaully argued that the water cools down quite drastically anyway in whatever brew device you use so the coffee won't meet 100 degrees water anyway.) So yeah, I'd be interested to hear what he'd take home from such an experiment. Or have you two spoken about your findings yet?

When I do use the boiling hot water straight from the kettle into a clever dripper, the temperature of the slurry is usually about 94-95 Celsius at most. I haven’t tried to measure a slurry temp while doing a v60 pour over, but maybe I should…

    This is exactly what I have been playing around with every day with espresso for the last 6 months with my wife as the test subject.
    Hard to do, but once everything else is standardized, it seems like her comments are:
    Low temperature is "Smooth but lacking in tobacco tastes".
    High is "Like a coffee shop, tobacco like tastes, some harsh flavor" (like over-extraction).
    In the middle is "Complex, full flavored, little to no harsh flavor".
    Variables that mess with the results include pre-infusion times, extraction flow rate, and extraction to coffee ratio.
    I am still working on this. If I make only one change somewhere, from day to day she picks up on it in her description.
    We once went on a wine trip together and she was able to tell in blind tasting what vineyards wines were from. Not your typical coffee drinker.

    Amazing video and good results!! That's how I always did it for the past 6 years. I start at a random temperature and kept changing the grind size/temperature every day, noted it down, and then follow the combination that gave me the best result for every bean. Nothing is constant but following a rule of thumb of a certain temperature for each roast is good to avoid losing beans. For example; using 98 degrees celsius water for dark roasts.

    Wouldn’t the brewing method also be a factor in how the temperature differences change as well, since the water will start to cool as soon as it leaves the source, combined with the amount of time it drains through the coffee? I love this scientific approach, great stuff as always!

  • @skatcat31

    This corroborates the tastings I've done at home where within 3C/6F differences there wasn't much detectable but within 4-5C/9-10F you could start to detect a difference. I have some theories on this but without access to equipment to separate compounds I wouldn't be able to say much.
    Really cool idea to explore further just to see what classification of compounds get extracted from sifted particles of the same size and shape at what temperatures.

    How do ya think days off roast factors in? I’ve still been in the school of thought that the further off roast a coffee is the hotter I need my water to ensure getting the most out of “what’s left” so to speak. I think I generally like just knowing my water is right at or fresh off boil as that is a pretty easy constant to lean on. I did used to like espressos brewed at lower temps, but often times the hustle of needing to move a line compelled me to utilize the heat to again get a lot of flavor in a shorter span of time. As a result I began leaning heavily on the “resting” coffees practices. Love your work homie!

Plus I also experimented with decanting brewed coffee before serving like with wine and have discovered that the coffee aroma and notes is more pronounced and the flavor of the coffee more distinct and flavorful. I welcome you all to experiment with decanting coffee like with wine prior to serving to see if it improves the taste of your coffee brew.

    Love the video and want you to keep on this line of exploration:
    My memory of the history: David Schomer used to preach something like 203 degrees Fahrenheit. Approximately 95 centigrade.
    Then people started dialing in different temperatures with different beans and roasts. PID temperature control became huge for home and commercial machines. All the “god” shots I’ve had were produced by temperature stable machine and baristas who took the time to dial in grind/bean/roast/temperature. In Seattle it seemed like a constantly fluctuating process that was impacted by ambient humidity and barometric pressure.
    At home, using press pots, mostly the espro, I get consistently good flavor when I get the pot to stabilize at around David’s temperature with the beans I enjoy. Mostly medium roasts. I always grind smaller than recommended as a like a little grit in the cup.
    In the olden days the synnesso both at Seattle SCA event consistently had the best shots and the baristas would gather round and dial in the shots.
    So I’d be really interested if you continued experimenting with different beans and roasts!

    This is a REALLY interesting video (which is also shot great!) that gets me thinking. Will the method you prep your coffee with matter as well when you choose a brew temp? Example, I got the Orea V3 collectors edition that claims to be very thermally stable, so I tend to use lower than my usual preference brew temps - eg light-medium roasts up to 94C and I have found that my cup is juicy, sweet and well rounded and almost without any bitterness. For my Chemex though, given that its glass, for the same coffees i always go up to 96C at least and I still get the same (almost) tasting cup. This is really worth an experiment and I’ll get my hands dirty this weekend 🙌🏻 Thank you Lance!

    As a grad student... a tip of the hat to you for humility. It is the foundation of science. Also, I've heard the same things, and now I get to do a ton of experimenting with water temp and my Robot (I love a good experimentation session). Related... perhaps this explains the variability in opinions on whether or not the Robot needs pre-heating. The designer insists it doesn't, yet some folks insist it does. This video allows for the possibility that everyone is correct, depending on the coffee, how it was roasted, and your individual palette. It's also somewhat frustrating because if you're not considering form factor, aesthetics, etc., in other words, if your primary objective is taste, then it makes a showdown between, say, a Robot and a Flair 58 even more a matter of personal taste. I found it quite fascinating that you preferred the Flair 58 without the heater (though the temp uptick at the end is interesting... I wondered about turning it off before pulling the shot to avoid that). I love my Robot, but I'm still Flair 58 curious. Your comments about the Robot vs. the Flair with regard to roast levels (I don't like dark, I usually gravitate toward medium roasts and sometimes light roasts) engaged my confirmation bias on my choice of the Robot... but now I need to make friends with someone who has a Flair 58 so we can do some experimenting (either way, I'm still pretty thrilled with the Robot, I bought it used from a friend and I've used it nearly every day).

    I haven’t read through all 340+ comments, but I was surprised you didn’t mention Jonathan Gagne’s work in your video too. He has a lot to say about temperature, advection, diffusion, and so on (of all the different chemicals in coffee), they all have different diffusion rates, so different temps change all of those in differing ways… iow, drink it at whatever brew temp makes it tastiest totally fits with that knowledge, given how different temps affect different chemicals that you may/may not like in coffee. I know you’re a big Gagne fan, hence my surprise! Hugo’s a very fine camera operator!

    I've done this experiment when I got my Sage Dual Boiler last year (because when you give me a variable to fiddle with, I will fiddle with it). For lighter roasts the higher temperatures were a smidge more bitter, but tasted way more impactful. At lower temps they just seemed a bit dulled down. Square Mile's Sweet Shop at lower temps was nice and fruity, but at higher temps it was like getting your head smashed in with fruitiness, which is what I like. For darker roasts there was only an increase in bitterness and not that much improvement to the overall flavour.
    Would be fun to see a lab break down the concentration of aromatic compounds in coffees brewed at various temperatures. That would be a more objective way to see if there's actually a difference in aromatic compounds based purely on differences in brew temp vs trusting a human's taste.

    I would be interested in learning more about how kettle temperature relates to slurry temperature in a pourover, and what the impact (or lack thereof) is of e.g. a declining temperature in the slurry versus a more consistent temp.

    Very interesting evaluation of brew temperature. I am especially interested in how the temperature effects are with espresso. The shorter exposure time could be a major influence with temperature and extraction, taste. I have used a ROK maunual espresso maker . Temperature is a major topic for manual machines. I preheat, preinfuse, slow ramp and full pressure to achieve great shots. It has been a given that light roasts are not an option due to higher temperatures required for extraction. Now, is this true and can extended preinfusion compensate?

  • @ondrejmitas3325
    @ondrejmitas3325 Год назад +1

    This fits with my espresso experiences exactly. Below about 92, there start to be problems; above that, there can be big differences, but nonobvious and nonlinear.

    • @GadgetsGearCoffee
      @GadgetsGearCoffee Год назад

      Interesting. I find medium to light I just keep it at 205 (96) and whenever I go darker (not oily or super dark) I'll just turn it down to 198 (92) and I'm happy

    And it´s indeed nice to see him before the camera as a second opinion.
    For me, temperature is a little bit tricky because I feel the Rest of my parameters are not on point (cheap grinder, switching coffees often). If you have to make a ranking of the most important parameters in coffee brewing. Where would you place the water temperature?

  • @elementonyoutube6556
    @elementonyoutube6556 Год назад

    Its nice to see the testing being done in a more exact method.
    The difference in bitterness reflects EASILY in a timed seeping of English Tea. In a 2 minute extraction, the bitterness in flavor is deeply prevalent in a hot water vs boiling temp.
    Now when I drink non-espresso (because I cannot control temperature with my machine) The Moka Pot also does VERY well in obviousness between a fast extract (high heat) vs slow extraction (minimal heat).

    Interesting experiment, I started doing a simpler but colder temperature surfing on my Gaggia Classic (starting the shot when the boiler turns off) and I found that I enjoyed the shots more. Now, I am not sure about the exact temperature, and I think my machine is running hotter than usual, but it opened my eye to being open to tweaking variables counter-intuitively.

  • @noahbrandon4802

    Brew temperature is something I've yet to play around with. I usually just set the kettle to 100C and wait a bit after taking it off. I'll definitely use the methodology shown here to see what works best for me.

  • @daRock1212

    Cool trial! Question, do you think results would be more pronounced in a percolation brew vs an immersion brew. Immersion brews assume in the EY calc that the TDS of solution is about the same as TDS in grounds, so it's at reaction equilibrium. I think the bitterness is from the slower extracting alkyloids that aren't quite at equilibrium, but the faster extractables are already in solution after the steep, regardless of temp. For a percolation brew, espresso or pourover, the assumption is that extractables are selectably removed with fresh water, through increased time or temp, and you might get a larger variance in TDS and taste difference. Just a thought!

    I've always dialed water temp in just like grind size; individually for each coffee. I always see the "off boil for light roast" recommendation as well, and for some coffees I do go there, but for other light roasts I stick down at 205 F/96 C. It depends on the roast, the pour pattern, the ratio, the age of the beans, and the user preference for the taste. In general I do brew lighter roasts higher temp than darker roasts but they vary wildly and can overlap in the temperatures I use for each. I use 205/96 as a first temp and base changes off taste from there.

  • @goldencalf5144
    @goldencalf5144 Год назад +1

    Higher temperatures increase the rate at which compounds dissolve even though solubility doesn't always increase. My guess is that most of the bitter compounds are less water soluble than the acids and sugars. Brewing at a higher temperature will leach out more of these bitter compounds in less time. Grinding finer will have a similar effect. That's why the Aeropress inventor recommends brewing at around 80C when using an espresso grind for the Aeropress.

  • @0whitestone

    Awesome video, I love anything with blind tastings more objective results. My method is always to start hot and lower the temperature in till it tastes the way I want it to. If it's clearly a darker roasts I'll just start at 95 or so but usually I'll start a boiling and lower if it tastes a little too bitter.

    • @LanceHedrick
      @LanceHedrick  Год назад +2

      I always prep my videos with an absurd amount of blind cuppings. I just only occasionally add them to videos because the slurping pisses some people off haha! And I start at 90 with darks. If you read the caption, I discuss this briefly.

      @@LanceHedrick Oh yes, I've noticed how much prep you put into your videos, I know you're extremely rigorous in your behind the scenes prep. I didn't mean to imply that that wasn't the case.

    That ‘stache though. This experiment is interesting. I haven’t done the side by side like that, but for me, I can’t really tell much difference between 90 and 100 in filter coffee. For espresso, that’s different. I had been brewing my regular dark roast at 93 for the longest time, then tried out 90 and it was quite a bit less bitter. The light roast I like is much less sour going from 93 up to 96.
