William's California Wine Concentrates are made from 100% Central Valley varietal wine grapes, picked at their peak and gently concentrated with minimum heat (never exceeding 180 degrees F.) under vacuum to 68 Brix. Sugar has not been added, nor is sugar needed to make 5 gallons of full-bodied varietal wine.
The 192 ounces of concentrate included in each pack is enough to make 5 gallons of wine with an alcohol content of 12 to 13%. Contains sulfiltes, so you do not need to add them before fermentation. Our California Wine Concentrates are also acid balanced, so you do not need to add acid or do an acid titration test (unless you want to).
What is Old Vine Zinfandel? It is Zinfandel Wine made by grapes produced by Zinfandel Vines that are 50 years old or older. Older vines, although they produce less fruit per acre, have deeper roots (down to 40') and tend to produce fruit with a more intense flavor and higher mineral content. Zinfandel is a grape that originated in California, and makes a red with a fruity softness that is quite pleasing even after a relatively short aging period.
Note: This includes concentrate only, and does not include yeast, oak, or other additives that may be needed to ferment 5 gallons of wine. For complete wine kits, see our William's California Wine Kits.
NOTE: This concentrate is unpasteurized, and should be refrigerated upon arrival. Refrigerated shelf life is 8 weeks from date of receipt.
