There's a can of Red Bull in my refrigerator, which I got from a company rep who was driving around in the Red Bull truck and stopped by a race I was at. That was August 7, 2002. I asked him what it tasted like, what flavor it was, and he said "Red Bull!". I still have never tried it.
It does make one wonder how many orienteers had their first taste of Red Bull in 2002. Anyway, Red Bull is one of those rare things that only improves with age, like eggs and bananas and raw hamburger. No bull.
I suppose you would always pour your Red Bull into a glass just in case there are any black spots in it.
