Vineyard Diary (updated 9-10-06)

A steady diet of hot days and cool nights, punctuated by a welcome respite yesterday and today, have led to rapid ripening across the vineyard.  The primitivo was essentially all picked over the last 8 days, and the barbera—whose acids are usually a little more stubborn on the descent—are rapidly approaching ripeness.  Some barbera remains available for sale on a provisional wait-list basis, and the harvest would be expected between September 16 and September 23.
