Right now I’m planning on brewing two beers. An IPA in a swamp cooler and a saison at basement temp which has been holding at around 76 + - a degree for a week. Whichever one comes out better will be the one for the wedding.
My recommendation for the saison or any belgian you plan on fermenting at a warmer temp is to at least start it out in the high 60s, or very, very low 70s, and hold it for a day or two. Then feel free to let it climb to the warmer temps. At the very least cool the wort down to at least 70 before pitching. While many belgians and saisons are fermented warm (some very, very warm!) most are pitched and started off in the 60s. For more examples pick us a copy of Framhouse Ales or Brew Like a Monk. Two great books on these styles.
Be creative. Yeah, the saison yeast works well for high-temp fermentation, but just because you use a saison yeast doesn’t mean you have to attempt a traditional saison.
