Fermented with whole packet of 2 year expired Fermentis WB-06. Added QA-23 packet for a few days (didn't seem to do anything). Pitched Wyeast 3278 Lambic Blend (28 May, 15 mfg date), and White Labs WLP655 Belgian Sour Mix 1 after crashing, racking, then bringing back to 64 F.

Tried this after two years in the basement. Still had some nasty pellicle on top. Didn't suck much of that through. Served at my buddy Jon's 30'th birthday party and it was a hit, with everyone really. It was only mildly sour and wasn't that funky. Definitely a crowd pleasing sour beer. I would make it again, but next time split the batch into one that was only fermented with sour culture and one that had sour culture pitched after a primary fermentation with regular yeast.
