Champagne Yeast

Champagne yeast is a special breed of yeast that can ferment sugars up to a much higher percentage of alcohol, up to 18 percent.

It is a bit of a select strain, and you probably won't find it in most wine store, so you will have to order it online.

Haven't tried it myself yet, and while I think it might be interesting, I haven't bothered yet, as I am mostly making alcohol to convert to vinegar, and we don't need that high a percentage.
