Alcohol Content
Alcohol content is the measured percentage of alcohol by volume (ABV) in a beverage, which must be declared on the label and accurately stated on the COLA application as required by TTB regulations.
In Plain English
Alcohol content is simply how strong a drink is, expressed as a percentage. A 40% ABV whiskey means that 40% of the liquid in the bottle is pure alcohol. This number must appear on every wine and spirits label, and it must be accurate within the tolerances allowed by law. For spirits, the alcohol content is typically also expressed in proof (which is just double the ABV percentage, so 40% ABV equals 80 proof). For malt beverages like beer, the ABV declaration is optional under federal law, though many states require it. The alcohol content is verified during the COLA review and must match the product's actual formulation.
Technical Detail
Alcohol content declaration requirements vary by product type. Distilled spirits (27 CFR 5.37) must state alcohol content as a percentage of ABV and optionally as proof, with allowed tolerances of plus or minus 0.3 percent for spirits. Wine (27 CFR 4.36) must declare ABV with tolerances that depend on the wine type: table wines labeled "table wine" or "light wine" need not state a specific percentage if the alcohol is between 7 and 14 percent. Malt beverages (27 CFR 7.71) are not required to state ABV under federal law unless state law mandates it, but if voluntarily stated, it must be accurate within 0.3 percent. ABV testing follows TTB-approved analytical methods, and the declared value must be based on the actual product, not the target formulation.
Why It Matters
Alcohol content is one of the primary product attributes that consumers, retailers, and distributors evaluate. Trends in alcohol content, like the growing popularity of lower-ABV products or the premium craft spirits segment pushing higher proof offerings, are visible in COLA filing data. For producers, staying within the allowed tolerances is important since a label declaring 80 proof but testing at 82 proof would violate federal regulations. For excise tax purposes, distilled spirits are taxed per proof gallon, making alcohol content a direct driver of tax liability.

Frequently Asked Questions
What is the difference between ABV and proof?
ABV (alcohol by volume) is the percentage of the liquid that is pure alcohol. Proof is simply ABV multiplied by two. So 40% ABV equals 80 proof. The proof system originated from an old British method of testing alcohol strength with gunpowder.
How accurate does the ABV on a label need to be?
Federal tolerances allow plus or minus 0.3 percent for distilled spirits and malt beverages. Wine tolerances vary by type and range from 1 to 1.5 percent. The declared ABV must be based on actual product testing, not just the target formulation.
Why do some beers not show ABV on the label?
Federal regulations do not require ABV disclosure on malt beverage labels. However, most states have their own laws requiring ABV disclosure, and many brewers voluntarily include it regardless. If ABV is stated, it must be accurate.
