September 4, 2013 – Tzabaco Rancho red grape sugar sampling results:

Merlot – 23.4 B (update: 24.2 B on Saturday – winery test)
Malbec – 19.5 B
Cabernet (winery test) – 20.0 B

We have finished our white grapes…nicely complete before this current heat wave. We are going to see a sugar bump from the heat in our red varieties but I am hoping that we can keep the later varieties Cabernet, Malbec and Petit Verdot on the vine for about another two weeks. The Merlot though is quite close with phenologically ready shoots and seeds…so it will probably be ready sometime this coming week.
