@Julie545 Gee, you're going to get so many different preferences- some people like a light roast, some like dark, some like super strong, some like flavored coffees and others think they're an abomination, some only drink decaf, some swear by drip coffee, some french press, we coffee drinkers are particular and fussy. Then there's a whole thing around what you add to it- some only drink it black, some with cream, some with milk, some with a non-dairy milk, some like evaporated milk, some use chemical "creamers". Sugar? White or brown, honey, artificial sweeter. See what a can of worms you opened?
Personally I go for dark, strong coffee. With cream, at least 15% BF. No sweetener. French press. Same brands are not necessarily available in all countries, but cheap coffee tastes cheap, I can tell you that. The higher quality the coffee is, the less acidic. And I consider flavored coffee to be an abomination 🙂 It's the wine cooler of coffee- something for teenagers.
