Made this last year but did not have as many currents. Am making 5 gal using 23 lb currents.
10 lb sugar brought s.g. up to 1.085
3 tsp pectic enzime
Nutrient and energizer according to their bottles.
4.5 gal water
pkg cote de blanc yeast
put currents, sugar, water, campden tabs split into 2 primaries.
added pectic 12 hrs later.
added nutrient and energizer.
24 hrs later added yeast. Made a starter with little wwarm water, some sugar and yeast. When it got going, added some must. It got to growing good and split it between the 2 primaries. Started it in the morning and pitched it in the evening about 10 hrs later.
Now stirring at least a couple of times a day, fermenting great. Temp is not real stable, have been getting it up to 72 degrees during the day, drops at night. Have had pretty good luck fermenting with the changing temps, but the wood stove goes out at night and the temp drops a little. Will keep you informed. Arne.
