I have a big triple brewday planned for Thursday. I'm planning on making a Saison, a Pyment and a Lambic-style sour - all using Gerwurztraminer must from a wine kit.
Tonight I'm (hopefully) going to start the sour wort process for the sour. The plan is to reconstitute Wheat DME in a keg with hot water, drop the pH to 4.5 with lactic acid, and innoculate with some Pils malt. After I pull out the grains, I'll seal and purge the keg and throw it in a cooler with hot water bottles. I'm hoping I can keep it hot enough to get plenty sour by Thursday. Then I'll heat it to 170F or so to kill off the bugs. I'm going to primary with US-05 for a few days before pitching a big starter of Orval dregs that I've stepped up a few times.
