A good black coffee is highly dependent on the beans and your own taste buds. There's some brews that folks describe with all these flavors, and it just tastes sour to me.
Also, there's this newer trend of adding tonic water to coffee and it's an abomination I paid almost $10 just to barely finish
People who act like drinking plain black coffee is a sign of being an adult are honestly the most childish of them all. Drink what you want, however you want, it's your choice!
i only started drinking black coffee because i have a client who owns an artisanal coffee shop. he often asks me to be one of the taste-testers anytime they're cooking a new menu.
nowadays my coffee is almost always black because i'm trying to keep my blood sugar on a healthy level 😅
