23C - Oud Bruin

BJCP Style: 23C - Oud Bruin

Though the Gueuze was more of a Final Boss, this brew is truly the last on the BJCP list closing out the European Sour Ale section. 

Oud Bruin is the lesser known partner style to Flanders Red with a "deeper malt character" according to the BJCP style comparison. 

The full recipe is on BrewersFriend but here's the TL;DR

Hops: Magnum for bittering and a late addition of Styrian Goldings

Mash complete

Leftover yeast from a recent Kölsch brew. The primary yeast will be so overpowered by the lacto and other bugs something neutral like this is fine here. 

Bag out. Heating up to boil

Away we go

2022-8-12 (+22): Wild American kicked so the OB got transferred into the sour keg.

2022-10-17 (+87): 2 month check. I forgot to get a pic but it's coming along nicely. Not too tart and not too sweet. Big malty character and this should turn out to be a good one. Will probably give it another month or so but it's getting close. 

2022-11-3 (+105): Tapped yesterday and took a chilled sample after allowing it to chill and settle overnight. This dried out quite a bit and is now clocking in at just a hair under 7% ABV. Taste is tart cherries and some milk chocolate - very nice! This should be great with a month or 2 of conditioning time.
