How much head can one beer have?

October is supposed to be cool in the North Country. Not today. It has been warm and extremely humid. Taking my dog for a walk this evening, I come back sticky and he’s panting. He heads for his water bowl, as I open the fridge and select a beer. A Starboard Stout from the Arcadia Brewing Company of Battle Creek sounds like it’ll hit the spot. So I sit a bottle on the counter, find the church key, and open it. Then the bottle erupts. This isn’t unusual, normally I take a gulp or two of foam as the beer settles down. But not this evening. The foam just keeps coming. This bottle is putting on a better display than that volcano down in El Salvador. I give up trying to drink all the foam and look for a chilled mug, but remember there all downstairs. So I sit a towel under the bottle and, with the interest of a volcanologist, watch one half of the beer foam out. I think I’m going to need another beer.
