Abstract or Summary
  • For this trial, established Pinot noir vines, located on the valley floor of the Umpqua Valley in Oregon were used. In 1996 and 1997 sixteen vines trained to the Scott Henry trellising system were separated into four different quadrants, determined by shoot orientation: Bottom canopy, shoots trained toward the ground; top canopy, shoots trained upwards; east orientation, shoots receiving the morning sunlight; and west orientation, shoots receiving afternoon sunlight. Yield components and fruit composition were measured for each quadrant. In 1996, wines were produced from fruit harvested by quadrant and subjected to sensory analysis. In 1996 the bottom canopy had higher yield, cluster weight, and titratable acidity than did the top canopy. In 1997 the top canopy had a higher yield than did the bottom canopy. In 1996 the east oriented canopy had a higher yield, cluster weight, and skin anthocyanins than did the west oriented canopy. Must soluble solids were not significantly different between vine canopy or orientation in 1996. In 1997 the west oriented canopy had higher brix, pH, and lower titratable acidity than the east oriented canopy. The bottom-east quadrant had a significantly higher yield than did the other three quadrants in 1996. There were no significant differences seen in quadrant yields in 1997. Significant differences were seen in wine attributes between the quadrants.
