>An acquired taste often refers to an appreciation for a food or beverage that is unlikely to be enjoyed by a person who has not had substantial exposure to it, usually because of some unfamiliar aspect of the food or beverage, including a strong or strange odor (e.g. stinky tofu, Gefilte fish, durian, hákarl, black salt, nattō, stinking toe, asafoetida, surströmming, or certain types of cheese), taste (such as alcoholic beverages, vegemite/marmite, bitter teas, salty liquorice, malt bread, unsweetened chocolate or garnatálg), or appearance.
Lots of people don't naturally like: avocados, olives, kombucha, stinky cheeses, offal, sushi, etc.
Even with coffee and tea, the acquisition works just as well if you drink decaf. (I only have one cup of caffeinated beverage a day, but I still occasionally enjoy a cup of decaf in the afternoons.)
