Only the 13 Chardonnay clones were harvested, as the Pinot noir vines were too variable to include in 1998. Chardonnay clones were harvested over a 7-day period from September 7 through September 14. Juice yield (adjusted for the differing amounts of fruit) ranged from 135 gallons per ton (Clone 132) to 173 gallons (Clone 4 and Wente). Fruit yields in the difficult fruit-set year of 1998 were similar among clones, varying only from about 5.1 to 6.4 kg/vine, except for Wente which yielded only 3 kg/vine. With the exception of cluster number, Wente was the most radically different in other yield components, having the lightest cluster (75 g), 40 to 50%lighter than other clones. This resulted from having somewhat fewer berries per cluster (89) and 40%smaller berries (84 g per 100 berries). Among the remaining clones, cluster weights generally fell into two groups, one at about 150 g (4, 75, 96, 121) and another at about 130 g (76, 78, 118, 134, 130, 131, 132). Triplicate fermentations of each Chardonnay clone were made at UC Davis and will be further evaluated in 1999.
