You haven’t had good tea or coffee then. The quality of the tea or beans, water temp, steep time, water quality, brew method can make or ruin any cup of coffee or tea. Get yourself to a nice local roaster or tea shop and have them brew you a cup. Can’t speak thoroughly on tea but for the best coffee order a pour over (chemex or v60 if they offer options) of a single origin bean (usually on their specials menu) that has tasting notes that sound good to you. Alternatively get an espresso of a single origin bean if you’d rather get punched in the face with coffee flavor. Guaranteed it’ll be unlike any coffee you’ve had before
