Ok, I tend to brew beer and only beer. My mom went to a winery and brought me back a gallon of wine grape juice and wants me to make her wine.
Uhhh. what do I do with it? No hops, no wort... I'm confused!
1) Add potassium metabisulfite to the must (grape juice).
2) Let stand for 12 hours.
3) Add yeasties. Ferment.
4) Go to The Winemaking Home Page and read about winemaking.
You might get some good tips from Yooper's Welches Grape Wine in the recipe database. Obviously, you are not using concentrate but it is a very informative thread.
Fermenting: Blackberry Wine
Aging: Mulberry Wine, Mint Mead, Dandelion Wine, Mesquite Mead
On Hand: Peach Mango Wine, Huck's Cider, Mulberry Mead, Orange Spice Mead, Cyser, Apfelwein, Maple Cinnamon Mead, Hard Cider, Brown Sugar Cider
What kind of juice? You can be crazy and not actually make wine with it, but add a little to a batch of beer and see what happens.
pyment??? That's what I would do.
