Well, like you, no offense intended, but just because you don’t understand something doesn’t mean it’s not legit. Folks in the wine industry or who are avid consumers know what these terms mean. I may not understand what a lot of terms used, say, in tree pruning or book binding or basket weaving mean, but that doesn’t mean the terms are meaningless to those who need to use them.
And second, there are plenty of times red wine is great with fish. Depends on the wine, the fish and how its prepared. You decide what you like, there are no rules that must be followed or else. And that’s probably a reason the guy was still a bus boy and not waiter.
Your point is well taken but as one who believes that words have or sure should have meaning, if they are to convey a thought to another human, concocting meanings to impress the inner circle does nothing to help those of us outside that circle.
And yes, I admit to not understanding the subtleties of Wine, it would be helpful to skip the fru-fru esoteric language and help more people understand assuming the point is to inform rather than impress.
