We picked the 2009 Syrah from Ken Hunt at Nolan Vineyards:

Here is some of the picking crew:

The dogs name was Syrah! Ken was really helpful. He drove his tractor with Erwins 1/2 ton bin on a trailer, so we dumped our grape tubs right into the bin. The picking was very efficient.

Here are the numbers:

• Clone: Durell
• Rootstock: 3309 or 1616 or 110R
• ~500lbs grapes picked into Erwins first half ton bin, 7:30 – 9:00 AM 11/1/2009
• Crushed at my house into Erwins second half ton bin
• Must temp 58 F.
• Sugar: 25 brix
• pH: 3.69
• TA: 5.5 g/l
• ~400 ml sample frozen for Vinquiry 3.5 analysis

Must volume calculations:

• Must volume in half ton bin: 44″x44″x6″ = 11616 in^3 = 6.72 ft^3 = 50.3 gallons must
• Wine volume estimate from grower: 7-8 gal/100 lbs grapes
  1. 7 gal/100 lbs: 500 lbs * 7 gal/100 lbs grapes =  35 gallons wine
  2. 8 gal/100 lbs: 500 lbs * 8 gal/100 lbs grapes = 40 gallons wine

SO2 calulations:

• Because pH is 3.7, add 70 ppm SO2
• From Beverage People catalog, 75 ppm SO2 = 4.9 ml/gal 10 % SO2 solution
• 4.9 ml * 70/75 = 4.6 ml for 70 ppm
• Pick 45 gallons, halfway between 50 gal measured must volume and 40 gal estimated final wine
• 45 gal * 4.9 ml/gal = 220.5 ml to get 70 ppm SO2 in 45 gal
• The fermCalc calculator comes up with 207 ml for the same conditions. Close enough.

6:30 PM: ADDED 220 ml 10% sulphite solution, and mixed it in
