CALCULATOR FROM PRODUCT SPECIFICATION
Castelli Romani
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?
13,699 kgtheoretical grapes required
0.83 ha · 8,302 m²theoretical minimum vineyard area
914theoretical 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 ÷ 73% = about 13,699 kg of grapes.Area: 100 hl ÷ 120.45 hl/ha = 0.83 ha = 8,302 m².Minimum vines: 0.83 ha × 1,100 vines/ha = 914 vines.
Result0.83 ha = 8,302 m² · 914 minimum vines
