I see there's a German-style bakery, but is "Peter" a fictitious character, an ideal that any such German style bakery would hope to project? We may be ready to pay Peterchen a visit in the coming days...and are looking forward to it.
The bread-as-heavy-as-a-brick notions partly describes certain varieties of bread in German-speaking countries. Baguettes are of course light in France and its former colonies that adopted the bread. It's a bit airy with a brilliant light crisp crust that snaps with a little pressure, and is never thick and chewy. Freshness is counted in hours, if not minutes, and never in days.
The notion that heavy sells the concept of German bread, is correct, but does not capture what it is, fully.
