I feel like we wine drinkers already knew this. I mean it is a
well-known property of cork taint that not only do you have the wet
cardboard flavor, but the other flavors that _should_ be there aren't.

So the logical conclusion is that either TCA somehow magically
destroys other flavors, or it suppreses our ability to taste them.

Note this well-known band-aid (hah) for cork taint:

I've tried it and I swear it helps. Brought an undrinkable
Savenierres up to drinkable, if not great.

But I haven't seen any blind tests.

In any case, when you do this two things happen: the must carboard
abates some, and other flavors come back some.
