Updated June 2026.
The bottles on a US liquor shelf are metric. The everyday sizes are a 50 mL mini, a 375 mL “pint,” a 750 mL fifth, a 1 L liter, and a 1.75 L handle. Those fills are authorized distilled-spirits standards under TTB 27 CFR 5.203. A fifth is 25.36 US fluid ounces — about 17 shots of 1.5 ounces. A handle is 59.2 ounces, about 39.5 shots.
Slang is leftover English measure. The glass has been metric since 1980. TTB’s January 2025 final rule (T.D. TTB-200) expanded the legal list to 25 distilled-spirits sizes, including 700 mL and several can fills. The fifth and handle still dominate the American shelf.
Common US bottle sizes
| What people say | Volume | US fl oz | 1.5 oz shots | Notes |
|---|---|---|---|---|
| Mini / airplane / nip | 50 mL | 1.7 | 1.1 | Legal fill |
| Half-pint (metric) | 200 mL | 6.8 | 4.5 | Legal fill |
| Pint (metric) | 375 mL | 12.7 | 8.5 | Not a 16 oz beer pint |
| Fifth | 750 mL | 25.4 | 17 | Default wine and spirits bottle |
| Liter | 1.00 L | 33.8 | 22.5 | Duty-free favorite |
| Handle / half-gallon (metric) | 1.75 L | 59.2 | 39.5 | The big plastic-handled bottle |
Exact math uses 1 US fl oz = 29.5735 mL. 750 ÷ 44.36 ≈ 16.9 shots, which everyone rounds to 17. See shots in a 750 mL bottle and what a fifth is.
What TTB added in 2025
27 CFR 5.203 now authorizes 25 metric fills for distilled spirits, cans included. New sizes of note: 187 mL, 250 mL, 355 mL (a 12-ounce can), 500 mL, 700 mL (the common European spirit bottle), 710 mL, 945 mL, 1.5 L, 2 L, 3 L, and 3.75 L. TTB also dropped the old cans-versus-bottles split, which is why RTD cocktails can legally sit in 355 mL cans.
That is permission, not a merchandising order. Most US liquor stores still set 750 mL and 1.75 L as the two prices that matter. A 700 mL import is 23.7 ounces — about 15.8 US shots — not a fifth. Do not cost a bar as if it were.
Wine uses 750 mL too, with a different drink count
Wine’s everyday bottle is also 750 mL (27 CFR 4.72). It is not 17 drinks. A 5-ounce pour of 12% wine is one US standard drink, so a wine fifth is about five drinks. Magnums (1.5 L), splits (187 mL), and 3 L boxes are wine fills, not whiskey handles. A “case” of wine is a trade unit of twelve 750 mL bottles — see how many bottles in a case of wine.
Beer is a different universe: 12-ounce cans, 16-ounce pints, and kegs measured off the 31-gallon US beer barrel. For those ounces see how many ounces in a keg.
Standard drinks hide in the same glass
Seventeen shots is a volume count. It equals 17 standard drinks only at 40% ABV. A 750 mL of 21% coconut rum is about nine drinks. A 1.75 L handle of 80-proof vodka is about 39.5 drinks — inventory, not a weekend. Count (mL × ABV) against NIAAA’s 14 grams / 0.6 fl oz of pure alcohol, not the nickname on the bag.
