"This should be a enough for a bottle of wine. We left one bagged cluster and those we couldn't reach...Brandon and I are going to try to make a full bottle of wine."
This will be batch #2. Batch #1 was a small scale experiment with 1 cinerea cluster that went better than we expected. After a week of fermenting on the skins and stems, John hand pressed the mash with a bag.
7.88 oz of grapes with stems:
4.36 oz must 55.3% yield
2.49 oz seeds/skin 31.7 %
1.00 oz stems. 13%
We were concerned with the amount of free juice that could be squeezed from the berries when we test for Brix. I didn't think there was much we could do with the berries, but John crushed them. He stored them in a plastic juice jug and after a week, presto, it was almost all juice:
Based on these results, 100lbs of Plainview Big Leaf Cinerea (PBLC) with stems would yield 55.3lbs of must. At 8.34lbs per gallon (s.g. of water) this is 6.63 gallons. Assuming 20% loss during racking, 5.3 gallons of wine or 26 bottles. Thus, we need about 4 lbs to make a enough juice to ferment in a bottle.
