Not a drinker, but I can also tell when my favorite brands change their recipes, and I hate it! I used to love Pringles, but a few years ago they changed something (I think it was their cooking process) and suddenly I couldn’t stand the taste OR the texture. Same with several other foods that I just don’t bother with anymore because they’re no good now.
I consider it motivation to learn how to make my own.
I know what you mean — not about Pringles, but Hershey bars taste bad lately.
