CALCULATOR FROM PRODUCT SPECIFICATION
Tarquinia
Vineyard area and production, grape-to-wine yield, release for consumption and latest marketable vintage. Numeric values use the shared structured database; quoted regulatory wording remains in the original Italian.
Calculations use only unambiguous specific or common values available in the database.
VINEYARD AREA & PRODUCTION
How much vineyard area is required, or how much can it produce?
14,286 kgtheoretical grapes required
0.95 ha · 9,524 m²theoretical minimum vineyard area
2,381theoretical minimum vines
How the result is calculatedThree steps, using the values actually applied in the calculation.

Calculation
Grapes required: 100 hl = 10,000 litres of wine. 10,000 litres ÷ 70% = about 14,286 kg of grapes.Area: 100 hl ÷ 105 hl/ha = 0.95 ha = 9,524 m².Minimum vines: 0.95 ha × 2,500 vines/ha = 2,381 vines.
Result0.95 ha = 9,524 m² · 2,381 minimum vines
