must be..i think i tasted some while i was smoking a cigarette (didn't wash hands first..LOL)

ps- talk about strong? i worked for pepsi for 2 summers many moons ago and the concentrate for pepsi and hires root beer is so strong that it is like soft fudge. came in a 1 gallon "wine box" type thing..and you add 1 gallon of the concentrate to 10,000 gallons of water..(then 20-88 lb bags of sugar!) the concentrate is so strong that i saw a guy burn a hole in his tongue when he put a bit of the concentrate on it.

needless to say, i can't drink pepsi ever since. the smell makes me gag
