I had actually meant to drink them at the weekend, but when I pulled them from their lying down position in the fridge there was a decent-sized beach of sediment running the length of each bottle, so I've been leaving them upright for the past couple of days.
The labels stumped me once again, and I still haven't checked what the technical difference between an Ur-Weisse and a Bräu-Weisse is. As usual with German beer the important information is in small print, so I read on the neck label that the Ur is a dunkels hefe weizenbier, and the Bräu the same in helles. Hidden on the main label is their respective strengths of 5.8% and 5.1% ABV.
My extremely limited German vocabulary tells me that "ur-" has the same meaning as the prefix "proto-" in English, so perhaps I'll do this in chronological order.

The first thing that struck me about Ayinger Ur-Weisse is that it's not very dunkels at all. I had been hoping for something along the brown-red lines of good old Schneider, but instead it's really rather orange. The flavour is understated by the usual standards of the style: lots of fruit there, of course, but it doesn't linger. There's a quick hit of wheaty-graininess, a touch of bitter fruit followed swiftly by a sweet banana finish, and then it's time for the next sip. It's a very easy beer to lash through which, considering its strength, is not such a good thing.
Perhaps unsurprisingly, Ayinger Bräu-Weisse is also paler than its contemporaries: a thin-looking light yellow. The banana flavour doesn't muck about here, and arrives full on the nose as soon as the bottle is opened. It carries on through the taste, but not in any kind of heavy or cloying way. Instead, there's a very unusual dry edge to this weissbier which serves to make it extra refreshing. Like the Ur-Weisse, it's an uncomplicated beer, though it's one which I think works rather better than its darker brother. Both create a direct line in my memory back to beers I've drunk while in Germany. I love it when beers do that.I reckon I'll be returning to Ayinger Bräu-Weisse when proper summer arrives. If proper summer arrives, of course.
