Dry White Wines, Spumante, Sauvignon Blanc, Semillon, Pinot Blanc, Gewurtztraminer. Temperature Range: 55-75 F. Alcohol Tolerance: 17%.
the tolerance of this yeast is around 17% and it will get there if the sugars exist.
I made a batch of mead using it, and tastes exactly like a dry white wine, there does not appear to be a thing as unfermentables for this yeast.
on a technical note, it has a very low amount of foam when fermenting, but if allowed to bottle condition gives a nice "champange fizz" when opened.
over all I'd give it 4-5 stars, its good but you need to know what you want to get out of it to begin with.
The yeast worked very well and produced a nice wine.
I used this yeast to ferment a Grand Cru International Sauvignon Blanc kit wine. The wine was very good but, to be honest, I didn't detect much difference compared to the Red Star dried yeast I would normally use.
The yeast took off super fast
