20 liter fermented with my house culture, with added wild yeast cultured from raspberries and Lactobacillus Plantarum.
No hops added, this needs to get as sour as possible.
5 liter left overnight in open fermentation bucket for spontaneous fermentation (first cooled to 55C to prevent melting of ferm. bucket.).
Hope this ferments down to 1.000, then 7% ish alcohol.
Once fermentation starts will be oaked with 1 gram/liter of american oak.
The chocolate/roast tones would do well with some forest fruits i guess. Add this in a few months.
