What software and tools do distillers and blenders use for alcohol calculations and dilution?

Members recommend several practical tools for accurate alcohol calculations and dilution, particularly for those moving away from manual table-based methods.

**Calculation tools:** - **AloDens** (https://www.katmarsoftware.com/alcodens.htm) — strongly recommended by members for reliable alcohol calculations - **Calcohol** — available on the App Store (£0.99), praised as "class" with handy features including shrinkage calculations for dilution; the only minor limitation is it calculates to 1 decimal point only - **Distilling-spirits.com free calculator** (https://www.distilling-spirits.com/tools/calculations/diluting-alcohol/) — basic, free option that doesn't account for shrinkage but requires no investment - **Vinolab** (https://www.vinolab.hr/calculator/gravity-density-sugar-conversions-en19) — offers a suite of useful calculators for gravity, density and sugar conversions

**Key consideration:** Shrinkage calculations matter for dilution work — Calcohol includes this; the free Distilling-spirits tool does not. Choose based on whether you need shrinkage factored in.
