# Limoncello Calculator

> Browser-based limoncello recipe calculator using Dario Bressanini's ratios and a local MiniZinc constraint solver.

This site helps users calculate a limoncello recipe from any partial set of known values: target batch size, base alcohol strength, target alcohol strength, alcohol volume, water volume, sugar, and lemon zest.

The calculator supports English, Swedish, Italian, French, German, Spanish, Portuguese, Dutch, and Danish. It can display metric, US customary, and UK imperial units while keeping the solver model in metric units internally.

## Recipe Model

- Lemon zest: 40 g per 100 g pure alcohol.
- Sugar: 50 g per 100 g pure alcohol.
- Maceration: 24-72 hours to reduce bitterness.
- Volume balance: alcohol volume + water volume + dissolved sugar volume contribution = total batch volume.
- ABV balance: base alcohol strength and final batch volume determine target alcohol strength.
