Wine Yield Calculator
Calculate how many bottles of wine you will get from a given weight of grapes.
Includes typical yield ratios for red and white wine production.
Estimated Wine Yield
Wine yield is the volume of finished wine extracted from a given weight of grapes or must. Understanding yield helps you plan production quantities, purchase the right amount of fruit, and estimate bottle counts before harvest.
The Formula:
Wine yield (liters) = Grape weight (kg) × Yield factor
Typical Yield Factors:
| Wine Type | Liters per kg of grapes |
|---|---|
| Red wine (free-run + press) | 0.65–0.75 |
| White wine (gentle press) | 0.60–0.70 |
| Rosé (saignée method) | 0.55–0.65 |
| Juice only (free-run) | 0.45–0.55 |
Worked Example:
You purchase 100 kg of Cabernet Sauvignon grapes:
Wine yield = 100 kg × 0.70 = 70 liters
70 liters ÷ 0.75 liters per bottle = ~93 standard 750 mL bottles
Factors That Affect Yield:
- Press type: A bladder press extracts more cleanly than a basket press
- Grape condition: Botrytis or shriveled grapes yield less juice
- Destemming: Whole-cluster fermentation retains stems, reducing effective juice volume
- Skin contact time: Longer maceration increases extraction but not volume significantly
- Pressing pressure: Higher pressure extracts more but lower-quality juice
Planning Reference:
| Grape Weight | Approximate Bottles |
|---|---|
| 10 kg | 9–10 bottles |
| 50 kg | 44–50 bottles |
| 100 kg | 88–100 bottles |
| 1,000 kg (1 tonne) | 880–1,000 bottles |
Practical Tips:
- Always account for 5–10% losses to lees, topping, and racking
- Keep a yield log across vintages — your specific press and grapes will show consistent patterns
