After all the picking, and picking over, and pressing, and settling, and filtering was done, I had 1.35 liters of very strong, very dark, very bitter wild grape juice. Cobbling together a recipe from various sources, but relying heavily on the information here and here, and the wine-making section of my copy of The Complete Guide to Self Sufficiency by John Seymour, I decided to add enough water to bring the volume up to 4.5 liters, enough sugar to (hopefully) achieve a sweet dessert wine, and to make a trip to a local home-brew supply shop for a packet of real wine yeast. If, John Seymour, the Grandfather of self-sufficiency thinks it’s worth the $2.30 for a packet of wine yeast, then I believe him!

So I added 2.65 liters of water to my grape juice, and stirred in a half a Campden tablet (to “sterilize” the grape juice, or kill the wild and rogue non-wine yeast that are likely to be in it) because my kitchen is full of bread yeast, which apparently makes poor wine. Then floated my hydrometer in a liter jar of juice. I got a beer and wine-making kit for my birthday with included this neat gadget that measures the specific gravity of a liquid via Archimedes’ principal, and thus tells you how much sugar (and therefore potential alcohol) is in your grape juice. As it turned out, not very much, which was no surprise at all. Eastern Ontario is not known as a grape-growing area, and despite the blistering heat we had his summer, my wild grapes were still far from sweet.

I added 1 kg of sugar, aiming for a quite sweet, fruity dessert wine, (which I figure I have a better chance of hitting than I do a “nice dry Chablis,” for instance) which gave my grape juice a specific gravity of 1.12, and a potential alcohol content of 16.5% I’m aiming high rather than low because all the sugar might not convert, and you need enough alcohol for the wine to preserve itself once it’s bottled, otherwise it will go off instead of maturing.

Then I added the yeast. And absolutely nothing happened. Now, this is my first attempt at wine, and I don’t know what is supposed to happen. My first batch of mead bubbled and frothed nicely when I added the (instant bread) yeast. The grape juice just sat there. I covered it over and left it overnight. In the morning I looked in the bucket, and still nothing, or not much of anything, anyway.

Time for intervention. I brought the temperature of the grape juice (which I should probably start calling “must,” to use the technical term) up to 75°F (my wine-making instructions are all in either American or 1950s British, which is OK, because my canning thermometer is in 1905 British units) by sitting a tall glass jug of hot water in the bucket, in case the problem was that the yeast was too cold. And I added a quarter teaspoon of “yeast accelerant” (those of you keeping score will have noticed that my home-brew shop purchases went slightly beyond a single packet of wine yeast).

Then I covered it up again, and sat it in a sunny corner of the kitchen, and tried hard not to check on it every 10 minutes. 12 or so hours later, it is definitely doing something that is starting to look like fermenting. Pinky-purple-y foam is forming on the surface of the grape juice must. Now all I need to do is figure out how to keep it warm for a week. Right now the bucket is sitting in the corner of the kitchen by the stove, because I just took two loaves of bread out of the oven. I’m hoping it doesn’t get too cold overnight, but I’m not turning the heating on just for the wine, that’s for sure. Maybe I’ll drape a blanket or something over it.
