re: So my friends were in awe that I drink Guinness.

But people don't know that. If you said 'final gravity' to the average beer drinker, they'd probably look at you like you were crazy It gets the heavy label because it is a stout, albeit a light one. I'm not saying it's correct, I'm just explaining that it's thought to be heavy out of sheer ignorance. I used to think drinking a Guinness would be like drinking motor oil, back before I tried anything but bud light.
