Clusters Fully Colored, Final Ripening Begins

This September was one of the warmest Septembers in recent history with 467 heating degree days, easily surpassing 2009's 402 heating degree days, and bringing 2011 cumulative heating degree days to levels seen in all but the hottest recent years.


We've hardly had any rain since mid-July, only a quarter inch in September.

As a result, the grapes are now uniformly black, around 19-20 Brix, and 2.9-3.0 pH.  Although the berries have softened, the skins are still fairly tough, skin tannins and flavors are not yet perceptible.  We now head into the final weeks of ripening.

As of this morning, still wet from last night's rain:
