Sit in the cab of the Grape Harvester at Tassel Ridge Vineyard as we harvest Brianna on Tuesday, August 23. Fruit quality is outstanding this year. And, the total yield was an astounding eight tons per acre! This translates to about 26 pounds per vine or 1600 pounds per 500 foot row. This means that we could fill the three Macro-bins which are slightly less than one 500 foot row. These grapevines were planted in 2005 and are now 11 years old.
