TTB Standards of Identity for Distilled Spirits: Bourbon, Rye, Vodka, Gin, and Rum
TTB standards of identity for distilled spirits under 27 CFR Part 5 establish the federal class and type designations for bourbon, straight whiskey, rye, vodka, gin, rum, brandy, tequila, and other spirits categories. Each classification carries specific production requirements — mash bill, distillation proof, entry proof, aging requirements, and permitted additives. Bourbon requires production in the United States from a mash bill of at least 51% corn, distilled to no more than 160 proof, and stored in new charred oak containers. This guide covers the standards of identity framework, category-specific requirements, distinctive product designations recognized in trade agreements, and the interaction with COLA on TTB Form 5100.31 and formula approval under 27 CFR 5.71.
TTB standards of identity for distilled spirits are codified in 27 CFR Part 5, establishing federal class and type designations that govern how spirits are produced, labeled, marketed, and taxed. Class designations include whisky (with subcategories bourbon whisky, rye whisky, corn whisky, straight whisky, blended whisky, and light whisky), vodka, gin, rum (with subcategories including light rum and dark rum), brandy, tequila (also a certification mark of Mexico), liqueurs and cordials, and specialty spirits. Each class has specific production requirements: bourbon requires production in the US from a mash bill of at least 51% corn, distilled to no more than 160 proof, entered into new charred oak containers at no more than 125 proof, and bottled at no less than 80 proof. Straight bourbon adds a minimum 2-year aging requirement. Similar requirements apply to rye whiskey (51% rye minimum), corn whiskey (80% corn minimum), and other categories. Bourbon and Tennessee whiskey are recognized as distinctive products of the United States in trade agreements. Products outside standard classes (flavored spirits, cordials, RTDs) trigger formula approval under 27 CFR 5.71. Class designation is filed with COLA on TTB Form 5100.31 and referenced by state brand registrations.
The TTB Distilled Spirits Standards of Identity Framework
TTB standards of identity under 27 CFR Part 5 provide the federal framework for classifying and labeling distilled spirits. The classification system operates through class designations (broad categories) and type designations (subcategories within a class). Each class and type has specific production requirements — mash bill, distillation proof, entry proof for aging containers, aging requirements, and permitted additives. Class and type designations flow through to Certificate of Label Approval, tax treatment, and marketing.
Whisky is the broadest class encompassing multiple subcategories. Bourbon whisky requires production in the United States from a mash bill of at least 51% corn, distilled to no more than 160 proof, entered into new charred oak containers at no more than 125 proof, and bottled at no less than 80 proof. Straight bourbon adds a minimum 2-year aging requirement in new charred oak containers. Rye whisky follows analogous rules with 51% rye minimum. Corn whisky requires 80% corn minimum. Straight whisky (any grain) requires 2-year aging in new charred oak. Blended whisky combines straight whisky with grain neutral spirits or other whiskies within specified limits.
Vodka is defined as neutral spirits distilled or treated after distillation to produce a spirit without distinctive character, aroma, taste, or color. Vodka has specific production and treatment requirements but no aging requirement. Gin is defined by production from neutral spirits with juniper berries and other flavor materials, with defined subcategories including distilled gin, London dry gin, and compound gin. Rum requires production from sugar cane products (cane juice, molasses, cane syrup) with specific proof limits. Brandy is defined as spirits distilled from wine or fruit, with fruit brandy and grape brandy subcategories. Tequila is a distinctive product of Mexico produced under Mexican regulatory framework (NOM) and imported to the US under labeling rules.
Products outside these standard classes — flavored whiskey, flavored vodka, cordials, liqueurs, RTDs (ready-to-drink cocktails), and specialty spirits — generally require formula approval under 27 CFR 5.71 before COLA. Bourbon and Tennessee whiskey are recognized as distinctive products of the United States in trade agreements with the EU, Canada, Mexico, and other trading partners, supporting export protection of these categories. Class and type flow through to state brand registration and federal excise tax treatment under 26 U.S.C. 5001.

The 8-Step Distilled Spirits Classification and Labeling Workflow
From production planning through TTB COLA approval, distilled spirits classification follows a consistent workflow anchored in production parameters and standards of identity.
Identify Intended Class and Type
Determine the intended class (whisky, vodka, gin, rum, brandy, etc.) and type (bourbon, straight bourbon, London dry gin, etc.) based on production plan. Class/type flows through the entire compliance chain.
Confirm Production Requirements
Verify mash bill, distillation proof, entry proof, aging container, aging duration, and permitted additives align with the class and type requirements under 27 CFR Part 5.
Assess Formula Approval Requirement
Standard bourbon, rye, straight whisky, vodka, and gin typically don’t need formula approval. Flavored spirits, cordials, liqueurs, RTDs, and specialty products trigger formula approval under 27 CFR 5.71.
File Formula Approval First If Required
File TTB Form 5110.38 through Formulas Online for formula-required products. Spirits formula processing runs approximately 2 days median at current TTB queue speeds. Sample analysis adds 15 days if required.
Establish DSP Production Records
Under 27 CFR 19, DSP records document production — mash composition, distillation, aging, and blending. Records support class/type substantiation.
Draft Label with Compliant Class and Type Designation
Class and type on the label per 27 CFR Part 5, mandatory statements, health warning per 27 CFR 16, alcohol content, and no prohibited claims. Age statements when applicable.
File TTB COLA on Form 5100.31
File through COLAs Online with front, back, wrap, and neck label images. Reference approved formula number if applicable. Distilled spirits COLAs run 6–8 days median at current TTB queue speeds.
File State Brand Registrations
Each state of sale requires state-level registration referencing the approved COLA. Control states operate separate listing processes for distilled spirits (17 US jurisdictions).
Distilled Spirits Standards Compliance Layers

Book a DemoWhere Distilled Spirits Standards Compliance Fails
Distilled spirits standards failures cluster around class designation errors, aging claim mismatches, and RTD classification.
Class Designation Error
Label claims a class the production doesn’t support — “straight bourbon” without 2-year aging, or bourbon produced outside the US.
Aging Claim Mismatch
Age statement doesn’t match actual aging duration. Age statements are among the most closely scrutinized areas of spirits labeling.
Missed Formula Approval
COLA filed for flavored, cordial, or RTD product before formula on file under 27 CFR 5.71. TTB holds the COLA.
RTD Classification Errors
Ready-to-drink cocktail classification as spirit vs. malt beverage affects taxation and requirements. Misclassification creates federal exposure.
DSP Record Gaps
DSP records under 27 CFR Part 19 don’t substantiate class/type claims. TTB compliance visits surface the gaps.
Distinctive Product Misuse
“Tennessee whiskey” or “bourbon” claims not meeting distinctive product requirements. Federal and trade partner enforcement risk.

Distilled Spirits Standards of Identity — Frequently Asked
Under 27 CFR Part 5, bourbon requires production in the United States from a mash bill of at least 51% corn, distilled to no more than 160 proof, entered into new charred oak containers at no more than 125 proof, and bottled at no less than 80 proof. No additives or coloring permitted (except water for dilution). Bourbon is recognized as a distinctive product of the United States in trade agreements.
Straight bourbon adds a minimum 2-year aging requirement in new charred oak containers. Straight bourbon aged less than 4 years also requires an age statement on the label. Bourbon aged less than 2 years cannot be labeled ‘straight.’
Rye whisky requires a mash bill of at least 51% rye, following analogous distillation and entry proof rules as bourbon. Straight rye adds a 2-year aging requirement in new charred oak. Some traditional Canadian whiskies labeled ‘rye’ don’t meet the US 51% rye requirement — those imports follow separate labeling rules.
Vodka is neutral spirits distilled or treated after distillation to produce a spirit without distinctive character, aroma, taste, or color. Federal rules under 27 CFR 5 permit certain flavor and color additions within specified parameters. Flavored vodka triggers formula approval under 27 CFR 5.71.
Gin is defined by production from neutral spirits with juniper berries and other flavor materials. Subcategories include distilled gin (redistilled with botanicals), London dry gin (with specific additional requirements), and compound gin (flavored without redistillation).
Rum requires production from sugar cane products — cane juice, molasses, or cane syrup — distilled at less than 190 proof. Subcategories include light rum, dark rum, spiced rum (formula required), and aged rum with age statements when applicable.
Bourbon can be produced anywhere in the US. ‘Tennessee whiskey’ as a distinctive product designation requires production in Tennessee under Tennessee state law. Both categories are recognized as distinctive products of the United States in trade agreements.
Standard bourbon typically doesn’t need formula approval. Flavored bourbon (bourbon with added flavor beyond permitted parameters), cordials, and RTDs using bourbon as a base do require formula approval under 27 CFR 5.71.
Spirit-based ready-to-drink cocktails typically require formula approval under 27 CFR 5.71 because they combine a base spirit with flavoring, sweeteners, acids, and other materials outside standard spirit classes. Classification affects both labeling and federal excise tax.
‘Light whisky’ under 27 CFR Part 5 is whisky produced at more than 160 proof but less than 190 proof and stored in used or uncharred new oak containers. Distinct from straight whisky and blended whisky.
Age statements identify the youngest whisky in the bottle. A bourbon labeled ’10 Years Old’ contains bourbon at least 10 years aged. Age statements are required on straight whisky aged less than 4 years. Voluntary age statements on older whiskies must accurately reflect the youngest component.
TTB Form 5110.38 is the Formula and Process for Distilled Spirits Products application, filed through Formulas Online at ttb.gov for spirits requiring formula approval under 27 CFR 5.71.
