i think you are bitting the dust of getting used to the taste of a drug, just like people who drink wine, beer etc. these are literally toxic & you get a natural avoidance response the 1° time you try, with very rare cases of acceptance without repulse

Coffee is one of my very favorite things in the whole world and I don't ever remember a time where I didn't like it. Right from the start I've always preferred it black - no flavors or dairy. Alcohol is a little different. Beer I loved from my first sip when I was probably 5 or 6. Whisky, gin, vodka, etc... I mostly didn't like until I learned a little bit more about the drinks and the flavors that alcohol can carry…

i remember once @ my great grandad house taking half a cup of wine around my 7 y/o; didn't tasted awful at all but i was expecting Fanta Grape Soda and i was thirsty...

but yeah, palate differs when you grow up; now if it's because social influence or effects from the substance, i dunno? but on taste & food (which for me it's different than a toxic substance); bitter/sour is rarely pleasurable for first timers and i can't deny that i'm in love with right after starting to ferment my stuff :)

Decaf that tastes like caf would be great. Unfortunately it seems to be impossible. Or at least I haven’t found it yet. The standard processes used to remove the caffeine seem to also remove enough of the other compounds to make it noticeably more watery and thin.

It’s possible, but very difficult. The problem isn’t really the removal of compounds, as far as I can tell, but moreso the change to the bean composition itself. Because the porosity increases so much roasting the decaf beans is much more difficult. Additionally, beans grind differently due to their porosity and brittleness. Basically, this means both the roaster and the grinder of the beans (and preparer of the coff…

Interesting. I do need to try some more decaf from roasters who know what they’re doing…

I roast everything myself so I can’t really comment on roasters, but I’d suggest looking for Swiss water processed decaf. Tends to cost more… but I think there’s an associated prestige that makes people care more about the bean quality if you pay for expensive processing.

More like, our own preference and enjoyment of the drugs compared to their detriments constructs our perception of these drugs.

Coffee, alcohol, pain killers, etc. These are all drugs that give the user enjoyment with very little down sides. This means that society has reserved a place for them.

Ease Up on the Espresso: If your sleep isn’t great lately, consider cutting back on the caffeine. Turns out, chugging coffee during sleep-deprived stints might shrink grey matter in parts of your brain. Not ideal if you’re trying to keep that brain in tip-top shape.

Know Your Limits: Everyone’s different when it comes to coffee tolerance. This study found that how your brain reacts to caffeine can depend on your genes—specifically, something about adenosine receptors. So, pay attention to how much caffeine you can handle, especially when you’re short on shut-eye.

Catch Those Zs: Don’t skimp on recovery sleep. After a brutal week, make sure to get some solid, uninterrupted sleep to bounce back. It helps counteract the rough effects of those sleepless nights and may even undo some of the caffeine-induced brain changes.

I agree with you about the experience, but nobody who really likes coffee goes to Starbuck for the taste:-). They are really addicted

It might be true that they're addicted to caffeine, but it's likely also true that they're addicted to Starbucks

Well with a place like Starbucks, they might be addicted to the sugar.

I believe Starbucks is selling sugar under the guise of caffeine.

This is Hackernews. Do things because you enjoy them? How can you enjoy life if you don't measure, optimize, and min-max every little thing, and write a little Rust program to track all the data you can post to Show HN? All food is fuel, nothing more, don't treat it as some experience to be savored.

If you buy caffeine pills as a stimulant, you are no better than those "addicts" at Starbucks at the airport.

I like coffee because it's a warm beverage, it tastes nice and of course there is the added benefit of the caffeine in the morning. That's about it.

There's no way I would be getting close to 400mg of caffeine and doing so by pills is something I marvel at.

I would say the majority of people drinking a normal cup of coffee (standard latte) a couple of times a day aren't getting anywhere near 400mg of caffeine. One shot of espresso is lucky to have 80mg of caffeine in it.

Well, I don’t actually like the taste of coffee and really drink it because of the caffeine effect.

I started drinking coffee at 26 because I got so tired after lunch that I almost passed out on my keyboard at work. This disappeared with the coffee intake. After years (I’m 42) I still don’t like the taste and don’t drink it at night or on weekends/holidays.
