Souring is done off unpasturized grain in a sealed water bath instead of the modern "kettle sour" way. Still using a lacto+brett containing yeast, but that doesn't really matter as the main sour profile comes from the soured grain, with brett flavours coming with bottle conditioning.
Tips:
-pasteurize wort before souring. This set of grains carry more than just lacto.
-source at 115 deg F for at least 24 hours. Longer generally makes more a sourer beer.
-be patient after bottling. Aging is important. The beer is perfectly good after initial bottle carb, but the aging brings out a lot of goodness. Even after 5 weeks aging, the beer is fantastic.
