Find the alcohol by volume of a mixed drink from each spirit's volume and ABV plus any mixer volume.
One spirit per line: "<volume in mL> <ABV%> <name>".

What this means
Multiply each spirit's volume by its ABV to get its pure-alcohol contribution, add them up, then divide by the total volume of spirits plus mixer. The result is the cocktail's ABV as a percentage. Common spirits: vodka/gin/whisky ≈ 40%, Aperol/Campari ≈ 20–25%, vermouth ≈ 15–20%.
ABV stands for alcohol by volume — the share of a drink that is pure alcohol. For a cocktail with several spirits and a mixer, the finished ABV is the weighted average of the alcohol in each ingredient divided by the total drink volume.
Formula
ABV = Σ(ingredient volume × ingredient ABV) ÷ total drink volume

FAQ
How is this different from the Cocktail Calculator?
The Cocktail Calculator focuses on servings, calories, and unit counts. This tool is centered on ABV and finished strength from your ingredient volumes.
Do syrups and juices count as mixers?
Yes — any non-alcoholic volume dilutes the drink. Enter their total volume as the mixer so the finished ABV is accurate.
