Dang. I did not expect so much to be covered in such a short amount of time. Coffee, beans, fermentation, location/altitude, roast, caffeine and chemical reactivity in the brain, brewing methods, all the way to drinks in the shop. Clearly there is a ton more detail that can be explored, but what a great introduction!

[@TDubsKid]

the keurig brewing method adds a nice rounded plastic taste to the coffee.

[@ainmhiwitch7494]

TDubsKid for real. I cry when I have to drink Keurig coffee lol

[@samueltheriault4790]

Always a good Idea tout heat a plastic cup with 3 hundred degrees feary water!

[@milktea4270]

I dunno, my Keurig doesn’t give my coffee a plastic taste, and I’m buying coffee from restaurants every other day, so it’s not like I’ve gone taste blind. The taste of Keurig coffee, overall, isn’t bad at all, but I do prefer other brewing methods, as the Keurig produces a weaker coffee to me even when I use the “strong” brew setting. Not bad enough for me to toss my Keurig- I’d rather just add another coffeemaker to my “collection,” preferably a Vietnamese or French coffee press. I’ll have the Keurig for convenience and one of those two presses for strong, roasty perfection and the ability to pick out and grind my own coffee beans.

[@GoogleUser-ge5hi]

[@izackredmon1725]

I love to see that there are still people out there that are infatuated by coffee and what it takes to make a good cup of coffee. I love coffee. I buy my beans close to roast date from local dealers. I grind them. And I brew each individual cup for myself. I love it. Most people think that coffee is just a simple cup with milk and sugar, but it's so much more complex than that. Love this video!!!!

[@infusedwithsepticpuss]

Indeed my friend :) Some of my most memorable conversations were shared over a piping hot cup of espresso. Good people deserve good coffee!

[@micahofcaferoberto]

+2% milk wow. I hope that I can taste a good coffee someday!

[@infusedwithsepticpuss]

I hope you can too! you deserve it.

[@andrewmonfort4881]

I hope you pay attention to how the flavor changes over that first 10 days from roast date. Depending on the roast, chemical reaction continue for up to 2 weeks after roast (thus the off gassing and increase in container pressure if you keep them in a sealed jar or tupperware), with the "flavor peak" (subjective) generally 3-8 days after roast. It's fun to play with a standard cupping method each day to try and notice changes in the flavor development, and then try something different for the second cup.

[@joebobmarley2854]

Exactly. It's an art. And it's magical. Every different bean has different magical qualities.. Coffee goes stale after about 10 days after roasting it. So it's really important to grind freshly roasted beans. I was told that Starbucks actually roasts their own beans so it's always fresh..

[@padenbergdall3451]

This is amazing to see as a Roaster and Barista. I’ve recommended this video to so many customers who want to get into coffee and start exploring. This is what we need people!

Good for you Violet! It is an acquired taste, as even discussed early on here, but one you "get it", there's something warm, special, and even magical about it. And lots of variations that can be tried too, to either tweak the taste, or explore more variety.

[@milktea4270]

[@Somebody782]

1. Natural in comparison to - Washed is -> more sweet, less intense, creamier 2. High (African countries) - Low attitude (Starbucks/Indonesia)-> more fruity acidic, creamier, cancels bitterness 3. Stronger - Mild roast -> carmalized, chocolaty, bitterly but not overwhelming, savoury, but further from the bean taste 4. French press - thicker. ,texture, fullbodyness -vs. Quimex (idk) more clarity, more flavour, how the taste changes

I have tried many coffees in the US and I have tried many coffee traveling to Central, South America and Africa and all those coffee are really bitter and apparently it is because of the type of coffee they have and specially because of the process of getting the final dry coffee bean. The only coffee that was perfect in flavor, smell, bold, rich and not bitter was the Colombian Coffee and I learned why. Colombian coffee has a very precise process where they use clean water, they pick only the best red coffee beans , and most of the coffee plants are Arabica coffee plans. Really the best coffee.( I am not Colombian)

OMG ,YOU EXPLAINED EVERYTHING TO ME MAN , Because when i moved to the USA i was a kid and noticed that filtered and dark roasted coffee are weird for me back then but now i get it “The total emerging” coffee is the way we drink it back in 🇾🇪 YEMEN The production process for Yemen Coffee beans has stayed the same for over 500 years. Small family farms plant on terraced fields carved into the Yemen landscape. The coffee plants are raised in the old way, without any use of chemicals. Once the fruit, referred to as “cherries” are ripe, they are hand-picked. The beans are not removed from the fruit, but dry-processed together. The fruit goes through a special drying period in caverns, and in some cases, on rooftops .... thanks

[@windshieldlaugh7411]

This is so interesting! I like how humans grew to love coffee so much they invested so much time in it and for example found out how oxygen played a role. You don’t see that with cucumbers haha.

[@jztouch]

I’ve been lucky enough to visit several Kona coffee farms in Hawaii. One of the things that’s unique about their coffee is it’s all handpicked so they only use ripe red cherries. It’s an exceedingly high quality, smooth cup and is worth the high price. The best way to buy it is direct from the farm online so you know it’s fresh! Ka’u coffee is also excellent. I like to prepare it in a pour over.

[@teguhsuryadi5387]

it's less than 15 minutes but the amount of knowledge shared is really amazing!

[@josephsmilanick9925]

He is a good speaker and the talk is presented well. He is correct, that under anaerobic conditions, respiration ends with glycolysis, and the terminal product is lactate. However, in plants the terminal products are different. Under anaerobic conditions, respiration also ends with glycolysis, but the terminal products are not lactate but primarily acetaldehyde and ethanol, with small amounts of other compounds. Ethanol is what is measured to determine if the plant tissues are injured under low oxygen stress, among other metabolites. Another subject - it seems very unlikely that the tissues of the coffee would be oxygen deficient - plants consume oxygen but produce abundant oxygen, more than they need, within their tissues as a byproduct of the oxidation of water during the photophosphorylation step of photosynthesis. All atmospheric oxygen is likely a result of this reaction in plants. My guess is a major difference between low altitude grown and high altitude grown coffee would be the thermal environment. Plants grown at higher elevations with mild days and cold nights typically have a high content of acids and complex secondary compounds that contribute to flavor, while those grown at low altitudes, especially in the tropics, metabolize the acids during their warmer nights and don't develop complex flavors. Wine grapes are an example of this - they are sweet but don't have complex flavors when grown in warm places (especially the nights) - you need cold nights (like Napa Valley or Paso Robles) to get grapes with complex flavors and deep color for wine making. Sorry for the prior lecture - I am plant pathologist.

If you liked this video, you may also want to know that There are advantages and disadvantages to consuming coffee. One population study on 4 million international individuals found that daily, consistent coffee consumption led to 8-28% reduction in all-cause mortality (prevention of chronic disease)! On the flip side, too much coffee can result in negative side effects, such as headaches, ear ringing, nausea, vomiting, and gastric distress.

[@scd6969]

I have been a coffee brewing enthusiast for about 5 years.. dove head first into the dark arts only to be consumed by all if the technicalities of brewing methodology. And yet instill learned quite a few things in this video that I didn't know. Such as how caffeine actually works in affecting how we sleep. Or how altitude affects the coffee cherry development and thus the flavor of the cup. Or how fermentation alters the beans in a natural process (I thought it was just that more of the cherry is left behind on the bean this adding flavor but that isn't the whole story and, actually theres a process for thst specifically the honey process iirc). Anyway this was a great video. While it doesn't cover quite "everything" as the world of coffee today is largely the espresso game (most of which was ignored in this presentation, for good reason as it is a truly a rabbit hole not for the faint of heart) it really is a fantastic overview that will bootstrap a person's coffee knowledge to level of a budding connoisseur :) Great job.

[@sahajsomani9193]

Hi Chandler, Thank you so much for sharing all this knowledge about coffee, I genuinely feel much more educated now. Can you also maybe present your view on the after effect of each kind of roast.? I normally try to avoid the dark roast because it leaves my mouth dry and makes me feel really thirsty. Also, how is freshly brewed different from expresso? I find an americano much smoother than a freshly brewed coffee at Starbucks and also drinking freshly brewed gives me a rush and wears me down pretty quick, whereas, the americano has no such after effects and keep me going nice and smooth. Any thoughts on that? Thank you in advance!

[@aletemaso]

I have to admit I have never been too much of a coffee drinker but this video gives you very helpful clues in order to buy coffee. I saw myself when you were explaining the supermarket situation with tons of options to choose from and no idea about coffee. Thanks. Keep up the good work.

Fascinating about the beans grown in high altitudes undergoing aerobic respiration, leading to nice acidic tastes. Chemistry truly is a wonderful science

You taught me everything I wanted to learn about coffee. Thanks!

[@thecapone45]

Learning a lot. This is cool. I will say, one thing I don’t particularly like are snobs on certain things. I see it with cigars, liquor, cooking, and here, in coffee. Honestly, if you’re got a Keurig (which i don’t have), go for it. If that’s what you like, go for it. Same for instant coffee. Personally, one of my least favorite things about getting into something new are the snobs who insist things get done a certain way. If you like your way, do it. Some people don’t understand that.

I don’t want to come across as rude or anything like that, I just legitimately want you to know for the future; the portion where you spoke about anaerobic respiration wasn’t 100% correct. Yes, when humans and animals undergo anaerobic respiration lactic acid is a byproduct. However, when plants undergo anaerobic respiration sugars are broken down into ethanol, carbon dioxide, and ATP (energy). This is also known as fermentation, which you spoke about earlier in the video. I don’t want to be “that person” that corrects people’s KZbin videos, but if I were in your shoes I would want to know if I were accidentally misinforming all the people that I was trying to teach, especially about science (my major, which is why I’m passionate about it enough to leave a comment). I found this information in one of my bio textbooks from uni, but you could fact check it just about anywhere, in case you want to make sure. I genuinely hope this helps!

[@troywilliams8811]

you're right!

[@shanpadarath2931]

Thanks. I stopped listen to him once he started comparing anaerobic respiration in animals and plants.

Frankly I don't believe that at the altitudes where coffee is grown there would be insufficient oxygen for normal aerobic respiration. We're talking 1-2,000metres (3-6,000 feet for the metrically challenged). Most humans don't even notice any oxygen depletion until over 3,000m . Coffee grown at altitude may certainly have a different flavour but I'm sceptical about anaerobic respiration having anything to do with it.

A quick glance at the oxy-hemaglobin disassociation curve will reveal just how wrong you are. What you "believe" and what is true are quite different, it seems. Feelings are best left out of science.

[@ildisiri]

Are u paranoid enough to think he's actually deliberately trying to misinform people in a video about coffee, or did you type that to have an excuse to be "that" guy?

[@CamilaElla-c1b]

This is a fantastic video. It's clear and easy to understand your explanations. Thank you for providing this information.
