We got lucky this week and didn't have the five days of 90+ temps that were expected. With nearly all clusters fully colored, and individual berry Brix readings in the 20's, we did our first cluster measurements today.
4 clusters per sample; 2 clusters from 2 rows,
each row sampled 1/3 in from each row end.

Compared to the past several years, this year's crop is ripening in a time frame that most closely resembles 2008's crop. 2012 is approximately one week ahead of 2008; the current forecast through mid-October is similar to slightly warmer than 2008.
