Barbara Pleasant’s Rhubarb Wine Recipe (3 gallons)
12 pounds rhubarb, cut into one-inch pieces, frozen and thawed, placed in fermentation bag
5 pounds sugar, boiled with 2 gallons water
1 pound honey, boiled with 1 gallon water, foam skimmed
8 ounces frozen white grape concentrate
One-fourth teaspoon grape tannin
3 teaspoons yeast nutrient
One and one-half teaspoons pectic enzyme
1 packet Lalvin 71B-1122 or
Vintner's Harvest MA33 yeast
My notes indicate an unremarkable primary fermentation, with significant cloudiness persisting until the second racking, after two months. Set in the basement for four more months, the wine cleared nicely, at least to my standards. Some recipes include chalk to enhance clearing, but limiting rhubarb to no more than 4 pounds per gallon, and a prolonged secondary ferment (necessary with natural wines anyway) seems to do the trick.
