Poppyseed Cellars

We racked the wine off of the gross lees.

• We racked each container into the bin we used for fermenting, so that the wine would be well mixed.
• We ended up with ~240 liters of wine.
• We did a Cu fining bench trial, using a control, 0.5 ppm, and 1.0 ppm as our samples.
  • We chose to go with the 1.0 ppm for the following reasons
    •  Slight improvement of the nose of the 1.0 over the 0.5 ppm.
    • We were worse off than last year, where we ended up doing a total addition of 0.9 ppm.
    • We decided that if it is not too expensive, we will also have  residual copper test done on this wine, after it has been racked again.
  • Addition calculation:
    • 240L of wine
    • 0.389 mL/L 1% CuSO4 solution = 1.0 ppm
    • 0.389 * 240 = 93.4 mL
  • We added 93 mL of 1% CuSO4 solution to the bin, and mixed well.
• Finally, we pumped the wine back into the following, for a total of ~224 L. This means the measurement scale on the fermenting bin is off a little…
  • 110 L barrel (30 gallon)
  • 50 L barrel (13.2 gallon)
  • 57 L barrel (15 gallon)
  • 1 1 gallon jug (~3.5 L)
  • 1 3/4 gallon jug (~ 3 L)
