Vineyard Establishment Flashcards
Site selection for inexpensive high volume wine
Flat, fertile
Warm, dry
Mechanization, less sprays, ability to irrigate
Site selection for premium wine
Seeks to obtain healthy grapes if optimal composition (sugar, acid, color, tannin, aroma compounds) for style desired rather than cost cutting
Site selection logistical/legal/cost factors
- price of land within desired GI
- location, layout, and topography of site may have cost implications- like a frost pocket in vineyard
- steep slopes - no mechanization and labor is $
- Irrigation needs - source and cost
- Accessibility and distance to winery
- Proximity to towns for labor, supplies, cellar door sales, retail, or distribution

Rootstock choices consider:
Pests- nematodes (vitis champini)
Water- rupestris and berlandieri drought tolerant/ riperia water logged soil tolerant/ berlandieri salt
Soil pH - rupestris tolerant of acid/ berlandieri tolerant of lime
Vigor- riperia for low vigor/ rupestris for enhanced vigor
