I have been brewing a pumpkin saison for about 10 years now. It really works. I just brew 10 gallons of pumpkin beer, split the batch in half, pitch East Coast Ale yeast in half and pitch Saison yeast in the other half. The regular pumpkin beer is for Thanksgiving and the pumpkin Saison is for Christmas.
