Went out to dinner tonight with my gal. We had a few drafts before and during. The pints had no 'head' on them. We started discussing it and I told her that when I was a bartender many moons ago, we would never send a beer out like that. She said the head part was waste, I said no it wasn't. The head on a beer releases CO2 in the beer and makes it less filling so you don't bloat, plus it looks better. She was totally lost on the term 'Nickle head', meaning the height of a nickle of foam. Awh, the lost art of pouring a beer.
