Extracting yeast from yeast balls

[vhuy]

Hey,

Where I live now getting hands on any yeast, except yeast balls is almost impossible. Not even baking yeast is easily availible. I have some 10 kilos of pineapples I want make wine of, and I don't really think the yeast balls with all its off-flavours will make my wine taste any good at all. I assume the taste the yeast balls produces is because of all the odd stuff in them (like turbo yeast), so is there some simple way to extract just the yeast out of them?

I just tested with a small sugar wash and it seems that some nasty stuff (probably from the yeast balls) has floated to the top. Should I just assume that everything on the bottom is yeast?
