I was reading in Phil Markowski's "Farmhouse Ales" about the strain of yeast found in Saison Dupont. This yeast is highly unusual among ale yeasts: extra-attenuative, but prone to "giving up" especially at the temperatures around or below 70* (the ideal temperature for most ales). Instead, it thrives best between 85* and 90*F, like many red wine yeasts.
For these reasons, some people apparently believe that the Dupont strain is actually a wine yeast that has adapted to brewhouse circumstances.
I'm curious whether anyone here has experimented with using wine yeast strains for brewing ales. What were your results? I am considering some experimental batches, maybe trying other red wine strains (bordeux, for instance) at high temperatures to make saison.
