The name is the best entry point. Alt is German for old, and on a beer label it describes a method rather than a recipe or an era. When bottom-fermenting lager spread across Germany through the nineteenth century and replaced most of what came before it, Dusseldorf kept brewing the older way, with a top-fermenting yeast. The beer that resulted took its name from the fact that it had not changed.
Guggman Haus has one on for Oktoberfest, at 5.5 percent, and describes it as a copper-colored hybrid ale. The hybrid part is accurate and worth spelling out. Altbier is fermented warm with an ale yeast, then conditioned cold for an extended stretch the way a lager would be. The warm ferment gives it the character an ale yeast provides, and the cold conditioning strips out the rougher edges and leaves the beer clean. It sits in neither camp, which is the whole idea.
The brewery's stated notes are toasted bread crust balanced by a firm, snappy bitterness on the finish. That bitterness is a real marker of the style rather than a flourish. Altbier is noticeably more bitter than most German beers of similar strength, and it needs a malt bill with enough toasted depth to meet it, which is where the copper color and the bread-crust character come in.
Guggman Haus sums it up as an amber-hued relative of Kolsch. The comparison holds up: Kolsch is Cologne's pale version of much the same approach, warm-fermented and then lagered cold. The two beers are built on similar logic and differ mostly in color and in how hard the bitterness lands.
The Altbier is pouring now as part of the Oktoberfest celebration.
