Thanks to everyone who replied to my question about where to find
yeast. I found a couple of places by looking in the local Yellow Pages
under (surprise!) "Winemaking Equipment and Supplies." Another section
with the same places was "Beer Homebrewing Equipment and Supplies." One
place was a winery's store (there are quite a few wineries in southern
Indiana), and the other also sold garden supplies. Someone also told me
he had found supplies at a hardware store.
Here is a summary of what I was told about yeast:
- Since grapes tend to have yeast on the skins, you can let the wine
ferment without adding yeast, but the results can vary greatly. One
person said such wine turns out either *good* or *bad*. Also, wine from
kits _must_ have yeast added, I assume because the fruit has been
sterilized before canning. Other types of fruit are not likely to have
the right kind of yeast already on them, so yeast is needed.
- Yeast for baking bread _can_ be used to make wine, but not at all
recommended. I tried this some time ago, and ended up with cooking
wine, but not drinking wine. This wasn't a disaster, however, since I
use lots of wine for cooking.
- The kind of yeast you add determines the *** content of the wine,
and so determines how dry it is. The higher the *** content, the
drier the wine, since there is less sugar left unfermented.
