330 ml bottle from Bottle Shop, Salzburg. The only bottle they had, which wasn’t intended to be sold, but they kindly sold it to me nonetheless. Thanks a lot!
Bottle has no infos unfortunately, only a label with the name and a picture of hops and grapes.

Dark amber, bit brownish, murky body, with a medium, unstable, frothy, beige head.
Fresh aroma of grapes, wine, sweet barrel notes, barnyard, sour apples, some sweet malts.
Taste is sour, with dry wooden barrel notes, white wine, grapes, sour fruits, some berries, subtle wheat and banana notes.
Medium to light, slick mouthfeel, with an average carbonation.
Finishes sour, dry, wine like, a bit alcohol warming and with long-lasting wooden barrel notes.

Tasty, refreshing and quite easy to drink. Flavour isn’t as complex as the really lovely nose, but also has pleasant wine and barrel notes, with notes from the base beer (a Weizenbock) coming a bit from the background. Very nice to see a brewery, that only brews traditional wheat styles mostly, do such a beer.
