• Example:
– 8X5 Spaced Vineyard
– 2 Drop Clusters x 0.26 lbs = 0.52 lbs
– 0.3~ t/a x 4.5 acres = 1.4 tons “Dropped”
– 50% “good fruit” in cluster x 1.4 tons= 0.7 tons
– 1,400 lbs “good fruit” in reject stream
– Lose 3.5 x’s more “good fruit”
@ two clusters dropped per vine
Out of site out of mind….

No labor costs in the field to drop the
fruit.
Changing thinning attitudes in vineyard.

Summary Conclusions:
Reduced capital investment for wineries (W $)
Fewer winery crush days/hours/minutes (W $)
Less money spent on labor thinning (G $)
Less “good fruit” being dropped during thinning (G $)
Increased hang time (W $)
Mechanical harvested and sorted fruit is superior to SOP hand
picked fruit* (G&W $)
Napa Wine/Vit Tech
1. Improve the quality of Napa Valley Wines
2. Provide some technical information to
members
4. Aid members in solving technical
winemaking and viticulture problems
5. Carry on enological and viticulture
research
