Also, for saissons, I settled on Wyeast 3724 for initial fermentation, then after 2 wks added Wyeast 3711. This ensures great flavor AND attenuation. 3711 is also great for strong golden ales like Duvel.
One of my original vials from last year (Wyeast Belgian Ardennes). Two step re-build, over the last week. Pitched this into a 1.062 dubbel yesterday at about three in the afternoon. It was bubbling before I went to bed, and I took this video at about 6:30 am. It is pretty vigorous.
