At the risk of bringing back a long-dead thread, I used this last summer as the basis for my own version of Saison Dupont. I followed all the advice here, but I brewed with Yeast Bay's Saison Blend. I ended up bottling half as is, and adding brett to the other half at bottling. The plain saison was great as soon as it carbonated. I left the half bottled with brett alone until Christmas. In side-by-side tasting, there was a subtle but pleasant funk to the brett batch. I really like the depth and complexity of both--it's amazing to get such a variety of flavors from such a simple combination of ingredients.
I'm down to my last couple of bottles, so I'm going to brew up another batch at the end of the week.
