4.1 kg blackberries for 5 days (not included)

Yeast: Omega Lactobacillus Blend kettle sour followed by Omega British Ale IV
Fermentation temperature/steps: Hold fermentation at 20°C for 24 hours once signs of fermentation are visible. Allow the temperature to rise to 21°C during the remainder of fermentation, following the dry-hop schedule. After adding the vanilla and blackberries, allow the berries to ferment out at 21°C.


31g Cassia bark
7g vanilla beans(pods)
4.1kg blackberries (frozen works best)

Mash the grains at 68°C for 45 minutes. Vorlauf until your runnings are clear, then run off into the kettle. Sparge the grains to obtain 23 litres of wort (depending on your evaporation rate).
Boil for 60 minutes. For the lactose, remove the kettle from the heat, stir in the lactose, return the kettle to the heat, and bring it back to a boil for the remaining 10 minutes.

Do not introduce the whirlpool hops at the first whirlpool, as they will inhibit the Lactobacillus blend. Pre-acidify the wort to a pH of 4.5, then chill the wort to 35°C and pitch the Lactobacillus blend. There’s no need to hold the heat at 35°C, but don’t allow it to drop much below 24°C. After a pH of 3.2–3.3 is obtained, reheat the wort to 82°C and follow the hopping schedule for the second whirlpool.

After the whirlpool, rest for 15 minutes, then chill the wort to slightly below fermentation temperature, about 19°C. Aerate the wort and pitch the British Ale yeast.
