ABV & standard drinks
Add up your ingredients and get the weighted-average ABV, plus how many US standard drinks each serving really pours.
TL;DR, verified June 26, 2026
ABV is weighted by pure alcohol divided by final liquid volume. A US standard drink contains 0.6 fl oz or 14 grams of pure alcohol, according to NIAAA (NIAAA standard drink definition, accessed June 26, 2026).
Dilution lowers final ABV by increasing volume, but it does not reduce the pure alcohol already poured.
BatchPour tools produce estimates for planning purposes only. Actual dilution, ABV, and ingredient yields vary by technique, ice temperature, and produce. Always taste and adjust. Drink responsibly.
Which number should I trust?
| Output | Direct answer | Source |
|---|---|---|
| Final ABV | Pure alcohol volume divided by total final drink volume. | Recipe math; verified June 26, 2026 |
| Standard drinks | Pure alcohol ounces divided by 0.6. | NIAAA, accessed June 26, 2026 |
| Safety decision | Do not use recipe ABV as a sobriety or driving decision. | CDC alcohol use basics, accessed June 26, 2026 |
Method: BatchPour sums pure alcohol from each ingredient, divides by final volume for ABV, and divides pure alcohol by NIAAA's 0.6 fl oz standard-drink definition. It is recipe math, not health, legal, or driving advice.
Frequently asked questions
What is one US standard drink?
NIAAA defines one US standard drink as 0.6 fluid ounces, or 14 grams, of pure alcohol.
Does dilution lower the alcohol in the drink?
Dilution lowers final ABV because it adds non-alcohol volume, but it does not remove the pure alcohol already in the serving.
Can this tell me whether someone is safe to drive?
No. It estimates recipe alcohol math only. Impairment and BAC depend on body, timing, food, medication, health, and local law.
