An older, heavy-set man has just set down my first glass of Kölsch, and I immediately do what we beer people tend to do: I stick my nose into the glass.
“It is beer; you drink it,” the man says.
“Okay,” I say, downing the beer in one gulp before handing him back the empty glass. He smiles, nods, and hands me another, ticking a second mark on my deckel. As he turns his attention to the table behind us, I furtively sneak another sniff of the beer.
