Calculate the final alcohol percentage of your Italian homemade liqueurs — limoncello, nocino, amaro, and infusions — using the dilution formula.
Final ABV (%) = Σ(Volume_i × ABV_i) / Total volume × 100 To reach target ABV: Diluent to add = (V_start × ABV_start / ABV_target) − V_start Limoncello example: 1000ml alcol puro (95%) + 1500ml syrup (0%) Total = 2500ml ABV = (1000 × 95) / 2500 = 38% ABV For classic 30% ABV: Syrup needed = (1000 × 95 / 30) − 1000 = 2167ml syrup
Use the dilution formula: Final ABV = (Volume of spirit × ABV of spirit) ÷ Total final volume. If you infuse 1 litre of 95% alcohol and add 1 litre of sugar syrup (0% ABV), your limoncello will be approximately 47.5% ABV — before bottling. Most traditional Amalfi limoncello targets 26–32% ABV, requiring more syrup.
Authentic Limoncello di Sorrento IGP uses pure grain alcohol (alcol puro) at 95–96% ABV for the lemon zest maceration. The infused spirit is then diluted with sugar syrup to reach 26–32% ABV for drinking strength.
Rearrange the dilution formula: Water to add = (Starting volume × Starting ABV ÷ Target ABV) − Starting volume. For example, to reduce 1 litre of 50% limoncello to 30%, add: (1 × 50 ÷ 30) − 1 = 0.667 litres of water/syrup.
Traditional nocino, made from unripe green walnuts macerated in 95% grain alcohol and then sweetened, typically ends up at 35–42% ABV. The dilution with sugar syrup brings the strength down from the 95% base.
Sugar does not contain alcohol, but it does increase the liquid volume. Adding sugar syrup dilutes the ABV. Dense syrup (2:1 sugar:water) also adds viscosity that can affect hydrometer readings — use our calculator for precise results based on volumes rather than instrument readings.
No. Italian law (D.Lgs. 504/1995 and EU regulations on spirits) prohibits unlicensed sale of homemade alcoholic beverages. Home production for personal consumption is permitted. To sell artisan liqueurs commercially, you must register as an authorised producer (deposito fiscale or regime accise).
