Wine Batch Size Calculator

Plan a nominal bottling volume from the number of 750 mL bottles and a percentage allowance for transfer and lees losses.

Enter your measurements

Estimate the finished wine volume needed to fill a chosen number of bottles.

Good to know

Is 750 mL the only bottle size?

This estimate uses standard 750 mL bottles. Convert your actual package volume to liters when planning a different format.

How much loss should I allow?

It depends on racking, sediment, filtration, and packaging. Use your own batch records for a better estimate.
