I've got a mash soured saison bottle conditioning right now that I'm chomping at the bit to try. The gravity sample before bottling tasted amazing, the lacto tartness from the sour mash really works well with the yeast. I used WLP566 because I was nervous about the fact that even White Labs says the WLP565 has a tendency to stall. Went all the way from 1.064 to 1.004 for a 7.9% monster.
