Brew #2 on the Sours program and its time to brew up an Oud Bruin or Flanders Brown Ale recipe we have affectionately called the 'sour brown dog'. Another job for the
Picobrew Zymatic which is fast becoming our go to machine for sours brewing as its a handy 10L batch size that works well with 10L glass demijohns for secondary conditioning in the shed.
Style Guidance:
- A brown, balanced, medium-bodied Flanders Brown Ale/Oud Bruin.

Racking
After an extended primary fermentation of 3-4 weeks I racked the beer off into a glass demijohn 10L for secondary fermentation where it has been aging and souring for just on 6 months now and about to be bottled anytime soon.

Bottling
Finally got around to bottling after a very long conditioning in the glass demijohn on Sun 30 Oct. Bulk primed with 105g of white sugar and was tasting very complex and sour but not overpoweringly so at bottling.
