I often use Belle Saison because I don't have fermentation temperature regulation, and that yeast is stable over a very wide temperature range. In addition, my beers with this yeast regularly have up to 25% table sugar, and I collect this yeast up to the 5th generation. After bottling the beer with Belle Saison yeast, I spray the plastic fermenter with Starsan ten minutes before decanting the wort and then I add US-05 yeast and it works without problems. A little Starsan that remains in the fermenter does not interfere with normal fermentation.
