Adenosine is a chemical your body slowly builds up throughout the day that makes you feel tired as it binds to the adenosine receptors in your cells. The caffeine you consume binds to these same receptors, preventing adenosine molecules from binding to them and inducing tiredness, which makes you feel more awake. To compensate for this, your cells create more of these receptors to allow adenosine to do its thing despite the caffeine binding to some receptors. As a result, not only does caffeine become much less effective over time, but when you are not taking in caffeine, you feel more tired than you otherwise would. The good news is this process is reversible.
Other reasons to avoid caffeine:
- increases anxiety
- reduces sleep quality
- increases gut activity in some people
- browns teeth
- costs money
- deforestation and worker exploitation are common in the coffee industry
Please feel free to dispute anything I have said in the replies.

I used to roast my own beans and make my own blends back in the day (2005) when I could find the green beans for around 75 cents a pound on ebay ( good luck with that now) and it was vastly superior to any commercial or even small-scale local roasters' beans. As far as the caffeine difference in degree of roasts- a just past first-crack with a little green still inside will have you doing the Mexican hat dance in the corner after a single cup. It's kinda grassy tasting but if you are familiar with the effects of cocaine the buzz you'll get is similar. I'd say my favorite bean is Kenya AA and I don't care how it is grown or if it is sustainable. If harvested by slave-children guarded by psychopathic child-soldiers with dead eyes I could care less. I've found commercial coffee no matter who you get it from or it's provenance just ain't that great. And that includes you Starbucks.

We used to have a tabletop roaster, the i-roast. (It looked like a coffee maker) My wife wanted me to BURN the beans. To leave the roaster on high so long that the beans would turn black and all the oils would be on the outside of the bean. The roaster would spew smoke out the top. She loved it. I personally couldn't stand that stuff. I'm more of a light-medium guy. We don't roast our own anymore, but we definitely grind fresh each morning.

If you want light roast coffee beans you can just insult them based on looks like how ugly it looks. But if you want dark roast, you really need to get into their heads and mind ask it why their fathers left them. Careful not to burn them too much because if you roast them just right it really brings out the flavor. No need to thank me Adam, I am a professional after all.

Light roasts are better than dark roasts. I grew up in Boston. Now live in Seattle. And the coffee, traditionally roasted lighter in the New England Roast style than the darker West Coast style inspired by Italian coffee and used at Starbucks, is way better in the Northeast. Even artisanally roasted coffee in Seattle tastes like boiled charcoal.

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.

I never drank coffee for most of my life until I left my ex. I took the coffee maker with me and on my 1st morning in my new apt. I brewed a pot and have never looked back. I'm now one of those people who has to have a cup of coffee every morning and when I run out of the good stuff I use instant. (Don't judge)

I've been roasting on the BBQ for 5 years now. It is hard to hear beyond first crack so I do about 10 minutes at 450F (per the cheap indicator on the BBQ. I suppose I could experiment further but I'm happy with the relatively light roast.
Just did 4 x 1 liter batches this morning. Took an hour.

Hi Adam, did you know that in SE Asia (Singapore & Malaysia, coffee is roasted with sugar and margarine? It is very difficult to find roasted coffee without sugar and margarine, except the boutique stores. Just giving you a FYI. Keep up the good work, enjoy your videos.
