The US and Regulation 27 CFR 5

What Does US Regulation 27 CFR 5 Require?

The regulation establishes a so-called Standard of Identity for each spirits category, an official definition that precisely describes which characteristics a product must have to be sold under a given name. For vodka, it requires, among other things, a minimum strength of 80 proof, meaning 40% ABV, noticeably higher than the European 37.5% ABV.

In addition, vodka in the US may not be marketed as aged and may contain only a limited addition of sugar and citric acid without losing its category status. These limits have remained unchanged for decades.

The TTB publishes these Standards of Identity publicly, so producers can check before launching a product whether it fits the desired category. If it fails to meet the requirements, the drink must be sold under a different name, without the protected term vodka.

What Changed with the 2020 Reform?

Until then, the law required vodka to be without distinctive character, aroma, taste, or color—a phrase that pushed many new, deliberately flavor-forward products into a legal gray area. The TTB justified the removal by stating that the old wording no longer matched customer expectations, which had long since come to embrace a wide variety of vodka styles.

Since the change, producers may bring vodka with a subtly perceptible distinctive profile to market without leaving the category. For labels, this means more freedom in describing flavor and production methods.

What Is Vodka in the US Still Not Allowed to Do?

Despite the relaxation, clear limits remain: aging in barrels is still excluded, as is unlimited addition of sugar and citric acid beyond the permitted amounts. These points still clearly separate vodka in the US, legally speaking, from categories such as gin or whiskey.

Why the Change Opens Up Labels

For consumers, this mainly means that the word vodka in the US today says less about flavor neutrality than it once did. Anyone who values a particularly neutral style needs to pay closer attention to producer information and label descriptions, rather than relying solely on the category.

How This Differs from the EU Rule

While the EU only prescribes the minimum strength and production method, the US long additionally defined the flavor character of vodka. This double requirement, minimum strength plus flavor neutrality, existed in this form in no other major market.

With the 2020 reform, the American definition moves somewhat closer to the European one, since both now judge primarily by production method and minimum strength. However, this doesn't create full alignment, since the higher minimum strength of 40% ABV remains in place in the US.

What Applies to Imported Vodka in the US?

Any spirit sold in the US, whether domestically produced or imported, needs prior label approval from the TTB, the so-called Certificate of Label Approval, or COLA for short. Only with this approval may a label go to market. Among other things, the agency checks whether the alcohol strength is correctly stated and whether the designation vodka meets the requirements of 27 CFR 5.

For imports, this means: a vodka sold in Poland as Polska Wódka, or a Russian vodka made to GOST standards, often needs to be specially reformulated or at least relabeled for the American market, because the US minimum strength of 80 proof exceeds the European minimum and some Russian levels. Producers therefore frequently bottle separate batches with higher alcohol content specifically for export to the US, even though the recipe and origin otherwise remain the same.
