I don't really know what is happening in this context. Maybe a lot of people have not much taste, or cannot disciminate between different tastes or things?
I don't understand anything about the words that go along with wine and beer reviews. I don't understand anything about using words like chocolate or nuts in describing the taste of wine or beer.
I do know what I like in my mouth, but that is also very subjective. It also changes over time and can differ from day to day. Some days I like a bitter hoppy beer, some days a fresh pilsner. Some days I like a softer red wine, some days it may have a 'bite'.
