9/28 Pick Day: We cleaned well the primary fermentation containers (PFCs), the grape crates, and the crusher/destemmer. This plus a fair bit of time planning took roughly six hours.
3:00: We took the netting off.
3:30-4:45: We picked the grapes, which after all the preparation work was very rewarding and peaceful. We were brutal in what we decided to keep. There was some powdery mildew and some shriveled fruit, but very little in what we kept. We estimate that we picked and used roughly two thirds of the fruit.
We got four not completely full grape crates:
The harvest was much less than we had expected. We changed from our
plan of using the 30 gal. PFC to using the 10 gal. PFC.
We optimized, marking only the 30-gallon fermenter because it was so time consuming, but later wished we hadnt when we had much less must than we planned for.
We fashioned a large funnel from the heavy plastic to channel the grapes from the destemmer into the grape crate we used as a crush basin.
We picked over the grapes again. We got 7½ gallons of must.
Measurements of the must taken:
Brix = 23
° (hydrometer)Brix = 22° , 22.2° (refractometer)
We used the hydrometer reading because it was more plausible given our last refractometer reading (and because we wanted the answer to be higher).
Temperature = 25° C = 77° F
pH = 3.35
TA = .58
Painfully arrived at since we are not good at adding liquid a drop at a time.
We did not standardize the NaOH.
These are good numbers; we are pleased.
Available alcohol = (23 3) x 1.083 x .59 = 12.78%. (This is exactly what we wound up with: 12.8%, what .)
6:50: We added 20 ppm K2S2O5
(very low).
= 2 x (.08 g/gal for 10 ppm) x 7.5
= .16 g. x 7.5 = 1.2 g.
9/29 Day after Pick: Wine at 62
° at 9:00 a.m. We decided to wait until later in the day when the wine would be warmer before adding the yeast.2:30: Wine is 67° .
7.5 gallons Þ 1½ packages of Pasteur Red yeast.
1.8g./gallon of Superfood Þ 13.5 g. for 7.5 gallons
@
½ ounce = ½ package Superfood2:45: Added the yeast and Superfood.
We speculated that the lower readings with the refractometer yesterday might have been due to our not stirring the wine. We stirred the wine and took a reading with the refractometer, getting 22.8° .
We also measured with the hydrometer: 23.9° .
The color of the wine has gone from a clear light grape purple yesterday to a deeper, somewhat opaque, raspberry purple this afternoon. The wine became even more opaque when we added the Superfood.
pH = 3.5 (in contrast to yesterdays 3.35).
Wine temperature as measured with the pH meter = 22° C
9:00: Temperature of the must = 68° .
We added the 7.5 grams of vinaflora oenos malolactic bacteria (1g./gal.) and 1.5grams if Leucofood (.2g. Leucofood/gallon):

Monday 10/5: No visible change. All stoppers
comfortably on.
