      @@Mebibit As someone who has worked both in an office and the production floor: every office worker should absolutely bug their superiors until they can get a tour of the production floor. It is extremely enlightening! Where I work we do a tour with all our new hires after a few weeks, even though we have to go to our customers and jump quite a few bureaucratic hoops to see actual production (we are consulting engineers). It is usually easier if you can organize a group of five or more people and you have to be patient for someone to be available. Just keep bugging your boss and ask your colleagues in the office to join in. I promise it is worth the effort!

      At my company we have a monthly safety participation (check eyewash stations, emergency exits not blocked, check for burnt out lightbulbs and many many more). It is random and everyone will get one each month. It will often bring office people to the production floor and vice versa. Many of our office employees once worked on the production floor anyway, like myself.

      @Minimalte 2 дня назад +7

      @maciejkepczynski8029
      Good question,
      Maybe you can measure the caffeine concentration in the ring line. But due to the constant change of coffee in the different treatment containers, the amount of caffeine rinsed out remains relatively the same. And for us, only the rest of the concentration in the coffee is important. So we would have no real benefit from it.
      If you put a measuring system behind each treatment container, it might work.
      But in this case, the cost-benefit factor would have to be seriously clarified.

    I ended up investing quite a lot in this whole decaf project. Bought three tasting kits from different roasters because the roast can make such a difference to the end product. I guess coffee is a hobby and I don’t mind spending money on things I enjoy, especially this opportunity to learn more about decaf. Really glad this global community of coffee enthusiasts exists and that we have people like James to help us learn more about it - totally worth the huge amount of work that’s gone into this project!

    If someone is interested, regarding the scary german compound words at 1:44, it's actually pretty easy to break down, you just slap words together, so
    "Coffeinhaltig, röstreizstoffreduziert" is more like
    "Coffein haltig, röst reizstoff reduziert" (technically reizstoff is also a compound word, and can be separated as "reiz stoff")
    which translates as:
    "Caffeine containing, roast[ing] irritant reduced" which is much easier to read for non germans I hope. Compound words look scary, but they're really easy to figure out actually.
    On a related note, I did mention "reizstoff" was another compound word and translated it as "irritant". If we split this one into "reiz stoff" it literally means "irritation substance".
    I do appreciate that james puts the effort towards getting pronounciation as right as possible, it shows a lot of respect.

    Footage and video was top-tier. I think I can speak for a lot of us that we’ve been waiting for years for this project. So far, you haven’t disappointed and we’re only two videos into the series. I look forward to the next video next Friday. I guess a question (two part) would be, besides taste and that you need to roast the coffee as soon as possible after it’s been decaffeinated, what do the roasters need to do differently to the decaffeinated coffee? For example, can they treat the same coffee (one decaf and one regular) the same if they were to roast them both? Or does the decaf need a different type of treatment? And, if the decaf does need different treatment, comma does that treatment change per type of method?

    • @ellaisplotting
      @ellaisplotting 2 дня назад

      Decaf definitely needs to be roasted differently (another thing besides added cost of processing that puts people off) as the opening up of the bean to extract caffeine changes the internal structure. It also appears darker due to the processing than the actual roast level is, so you need to take that into account when roasting. James goes into more detail on it in his original decaf video from a while back.

      Me too! It's not just about making it cool, it's about separating the drink from the notion that it's only intrinsic value is the caffeine. Coffee has fiber, vitamins, antioxidants, polyphenols and plenty of other things we've never really investigated really, and it's main value in my opinion, is how it tastes like. Historically you could only get really dark roast decaf from an undisclosed location and it seems like a shame. We need decaf that's actually tasty, eventually it builds more options for more people. And you can then enjoy 10 cups of a tasty beverage without risking insomnia and jitters.

    As a chemical engineer it was great to see the footage of the process. I had always suspected there would be some interesting industrial chemistry going on. P.s yes the sound of industrial sites is always intense, I still remember my first day or walking into an oil refinery and being struck by the intensity of the noise.

      @@patricksparksadventures yeah, standardized containers make transport and handling easy. For small farms and co-ops the issue is how big the containers are, cause it costs the same to ship a half empty container and a container full to the brim and sometimes smaller producers struggle to fill a container up.

    I have tried several packs of decaf coffee and IMHO, they taste weak e.g. a decaf flat white tastes like a latte.
    I ordered the tasting kit, so I am happy to try again.

    As always, fantastic content that was well written, well produced, informative and straight to the point. Something I learned from this video that I hadn’t thought about was the pure caffeine being sold. That really peaks my interest, and I’m curious how that affects profit / what the revenue breakdown is. It’s always awesome to see ways to increase business in sustainable ways via reducing waste.

Great to watch always learning, also from both your books too.

      Decaffinated coffee seems to be in huge demand for sure. To me it however does not matter if its decaf or not as caffeine seems to affect me very little. Like you can't use coffee to make me less sleepy in the morning + I have no problem drinking coffee in the evning and then still being able to sleep no problem afterwards. However I still really enjoy the taste of a cup of fine roasted coffee. That I never say no to!

    One thing I know. CO2 at liquid temps is a great solvent. Very very capturing of everything it touches. Then evaporate it to some extent. Or add to other things before coming to equilibrium.

    I switch to decaffeinated coffee for health reasons as a diabetic.
    The caffeine was driving my blood sugar up.
    I still occasionally use caffeine by putting in a measured amount in the form of caffeine pills but most of the time I just drink decaf.
    Then one time I accidentally bought instant decaffeinated coffee by accident. That was a mess because it clogs the filter.
    But I had to finish the jar anyway and over time the biggest thing I noticed was a huge decrease in waste. Especially wet smelly waste.
    Since I am not a coffee aficionado and since I drink my coffee with additives... Sometimes vanilla sometimes cocoa powder, sometimes cinnamon,.. always at least a little bit of half and half or cream... I don't notice a big difference since I was never into the nuances of freshly made black coffee from custom beans anyway.
    So now I prefer instant decaffeinated coffee.
    I might buy some premium coffee for when I decide to brew a custom cup of caffeinated coffee as a treat since I won't be using it on a daily basis anymore.
