What's interesting about beluga caviar is that it taste varies a lot. I've tried illegally caught Russian caviar and then I've tried some caviar from a sustainable farm and the former was way better for some reason.

I mean, I buy the farmed stuff because it's good enough for me, but I'm not exactly a super taster given my love for bitter stuff.
