I made a 10 gal batch of sour today. 2 gal was diverted and is fermenting on 3864 (Unibroue) and the Solera IIPA BRETT dregs from that "magic marker" failure that turned into something beautiful. The other 8 gal is in my demijohn with 3864 (Unibroue), Brett L, Lacto and the Mash Occur 15 sour mix. shit son!
