"beer served in cans is not beer ."

What about beer served in aluminum kegs (he asked in good humor)?

You know it never occurred to me that beer vom Fass (from the keg) also comes from an aluminum container. I suppose originally they were made of wood. In any event, as Hunter 112 points out, the beer is poured into a glass before it is poured down the gullet.

Good point.
