In the past, I made a blackberry wine on the whole fruit and fermented to dryness. Despite the fact that the fruit was removed after 5 days the wine had a distinct bitterness that was unleasant. A year later the wine is a bit better but still more bitter than we would prefer. This year I used steam-juiced blackberries and the final product is excellent. I have now made a steam-juiced blackberry, a cranberry and a peach. All have been outstanding. Next up a wild cherry and a pear. I am now a strong advocate of steam juicing.
Here is the recipe used for the blackberry:
Blackberry 2008
15 1/2 qt blackberries (steam juiced)
Sugar (SG 1.090)
6 1/2 t yeast nutrient
3 1/4 t pectic enzyme
3 1/4 t acid blend
6 Campden Tablets (crushed)
Water to 6 1/2 gal
Lalvin RC 212
Back-sweetened with sugar (SG 1.01)
Placed the juice, water, sugar, pectic enzyme, acid blend and Campden in primary. Pitched hydrated yeast 24 hours later (total volume approximately 7 gal). Within 12 hours fermentation produced lots of heavy, dense foam and a not so pleasant odor. Skimmed and removed dense foam twice. Heavy foasm was gone within 24 hours and replaced by "fizzing" and a light, white foam. Racked to secondary when SG was 1.054. Racked and topped up with about 3/4 bottle of banana wine. Made a mistake and added 6 more Campden. One month later racked and topped up with a couple cups water and 1/2 bottle dry blackberry wine; SG was 0.996 (ABV about 11.8%. One month later back-sweetened with sugar to SG 1.01.
