A little copper here, a little copper there…

I went out to top off all the wines.

I also checked out the ’12 LH syrah. There is still a little reductive nose going on, but a lot better after the splash racking.

I did a bench trial of CuSO4: 0.0, 0.5, 1.0 ppm. There was a noticeable difference between 0.0 and 0.5 ppm, but  I could not tell any difference between the 0.5 and 1.0 ppm.

I added 0.5 ppm Cu to all the containers:

  • 60 gallon barrel: 44.7 mL of 1% CuSO4
  • 15 gallon barrel: 11.3 mL of 1% CuSO4
  • 1 gallon jug: 0.7 mL of 1% CuSO4
  • 1 gallon jug: 0.7 mL of 1% CuSO4

We will let it sit a week while in Disneyland, and rack when we get back.
