How many litres of wine do 100 kg of grapes make?

As a typical estimate, 60 to 75 L depending on style: a red fermented on skins yields more (≈ 72 L) than a pressed white (≈ 65 L) or a direct-press rosé (≈ 62 L). The real figure depends on variety, ripeness, press cycle and whether you blend back the press wine — that's why the field is editable.

Why leave headspace in fermentation tanks?

During fermentation the cap and foam rise, so winemakers usually leave a free margin; in storage, vessels are kept nearly full to limit air contact. The tool's percentages are typical estimates you can adjust to your own practice.

Which barrel sizes can I add?

The common formats: 225 L (Bordeaux), 228 L (Burgundy), 300 L and 500 L. For any other size, add a tank row with its nominal volume.

Harvest yield and tank capacity planner

Estimate how many litres of wine your harvest will make (area × yield or total tonnage) and how many tanks and barrels you need, with a fill plan and an L/hL/gal and kg/q/t converter.

Default values are typical, editable estimates — not standards. Adjust them with your winery's own figures.

Suggested fill plan

The largest vessels are filled first; the remainder goes into the smallest vessel that can hold all of it, to keep ullage to a minimum.
