Wine Trial Introduction
• Wine A (Left)• Wine B (Right)
Please taste the wines and note:Preference is Wine APreference is Wine BNo difference between Wine A and Wine B

Topic of Discussion:High Speed Optical Sorting in the Field
– A) Contrast Traditional Processes– B) Describe Alternative Processes
• Mechanical Berry Sorting• Field Optical Berry Sorting
– C) Considerations with Alternative Processes• Viticulture• Winemaking

Cluster Thin #3
Hand Harvest #4
Field Cluster Sort #5
Winery Cluster Sort #6
Winery Destemmer

Traditional Hand• Pro
– Discrimination of Clusters– Reduced MOG– Longer Storage Time– Small Picks OK– Gentle on Vines– Etc.
• Con– Very Expensive– Crew Availability– Physical Labor Risks– Complexity of Logistics– Can Be Slow– Etc.

Traditional Mechanized
• Pro– Saves Money– Around the Clock Operations– Fewer Pieces of Equipment – Reduces Labor Input– Etc.
• Con– Indiscriminant Everything– Increased MOG– Shorter Storage– Vine Damage– Size of Pick– Second Crop– Etc.

Alternative Processes• Pro
– Saves Money vs Hand– Around the Clock Operations– Fewer Pieces of Equipment – Reduces Labor Input– Discrimination of Clusters Berries– Reduced MOG– Fast to Tank– Etc.
• Con– Indiscriminant Cluster– Increased MOG– Storage – Size of Pick– Second Crop– Varietal Differences– Etc.
