Jim,

I recommend starting with a Niagara wine made from Welches
concentrate. You appear to be located in the States, so you shouldn't
have any trouble finding the concentrate at your local grocery store.
The other ingredients are available at any homebrew shop. If you don't
have a local homebrew shop, look online.

Jack Keller's site lists several variations on this recipe. Some list
the specific quantity of sugar; others indicate that you should use
your hydrometer. Starting out I suggest that you skip the hydrometer
for now. It will be a nice wine whether it is bone dry or slightly
sweet. 1 lb of sugar is about 2 1/8 cups.

Keep everything clean. Minimize oxygen exposure after the first week
or so (use the airlock correctly). Rack every month or so (from
pitching the yeast to bottling should be 3 or 4 months). Bottle age
for a few months before tasting.

Good luck.
