TTB Wine Additive Approval and Winemaking Practices Under 27 CFR 24
TTB wine additive approval and winemaking practices are governed by 27 CFR Part 24 — the federal wine production framework. The regulations specify which additives and cellar treatment materials are approved for use in standard wine production, which trigger formula approval under 27 CFR 24.80–24.85, and which are prohibited. Winemaking practices such as chaptalization (sugar addition), acidification, amelioration, and blending have specific federal rules that interact with state wine production laws and appellation labeling. This guide covers the approved additive framework, formula approval for specialty wines, cellar treatment recordkeeping under 27 CFR 24, and the interaction with wine class and type on the COLA.
TTB wine production is governed by 27 CFR Part 24, which sets rules for winemaking practices, approved additives and cellar treatment materials, formula approval for specialty wines, and recordkeeping. Standard wine production uses approved cellar treatment materials — including sulfur dioxide (SO2), tartaric acid, calcium carbonate, malic acid, potassium bicarbonate, tannin, and specific fining agents — within federal parameters. Products using treatments outside standard parameters or ingredients that transform the wine’s fundamental character (added natural flavors, herbs, honey for specific styles) generally require formula approval under 27 CFR 24.80–24.85 as “special natural wines,” “agricultural wines,” or other specialty categories. Winemaking practices such as chaptalization (sugar addition), acidification, amelioration (adding water to correct high sugar/acid), and blending have specific rules — some governed by federal 27 CFR 24, others by state wine law. Cellar treatment records must be preserved under 27 CFR 24 recordkeeping requirements, supporting TTB compliance visits and appellation claim substantiation. Formula approval requirements for specialty wines run on the TTB formula queue (approximately 3 days median for wine at current queue speeds), separate from COLA queue.
The Wine Additive and Winemaking Practice Framework
Wine production compliance under 27 CFR Part 24 governs what materials winemakers can add to wine, how wine can be treated in the cellar, and what production practices are permitted for standard wine versus specialty wine categories. The framework rests on defined approved cellar treatment materials, approved winemaking practices, formula approval for specialty wines, and detailed recordkeeping requirements.
Approved cellar treatment materials include sulfur dioxide (SO2) for microbial control and oxidation prevention, tartaric acid and other acids for acidification, calcium carbonate and other bases for deacidification, tannin for structure and mouthfeel, fining agents (bentonite, egg white, isinglass, gelatin, PVPP) for clarification, and yeasts and yeast nutrients for fermentation. Each has specific federal parameters governing use levels and application in wine production.
Winemaking practices — chaptalization (sugar addition), acidification, amelioration (water addition), blending, and finishing — have specific federal rules under 27 CFR 24 and interact with state wine law. Chaptalization is prohibited in California but permitted in many cooler climate states. Acidification is generally allowed with specified materials. Amelioration has its own rules governing when water can be added to correct high sugar or acid. Practices outside the approved framework generally require formula approval.
Formula approval under 27 CFR 24.80–24.85 covers “special natural wines” produced with added natural flavoring materials or herbs, “agricultural wines” produced from fruits or agricultural products other than grapes, wines treated with materials or processes requiring prior approval, and other specialty categories. Formula filings on TTB Form 5120.29 run through Formulas Online at approximately 3 days median for wine at current TTB queue speeds. Formula approval must be resolved before the COLA is finalized on formula-required products.

The 8-Step Wine Additive and Winemaking Practice Compliance Workflow
From cellar treatment planning through TTB COLA approval, wine production compliance follows a consistent workflow anchored in federal and state framework analysis.
Identify Intended Winemaking Practices
Document the intended cellar treatment materials, adjustments (chaptalization, acidification, amelioration), blending practices, and finishing operations for the wine.
Verify Federal Framework Coverage
Confirm intended materials and practices fall within 27 CFR Part 24 approved framework. Practices outside the framework typically require formula approval under 27 CFR 24.80–24.85.
Check State Wine Production Rules
State wine laws often add to federal — California’s chaptalization prohibition is a notable example. Confirm state-specific rules for the production location.
File Formula Approval for Specialty Wines
For products requiring formula approval — special natural wines, agricultural wines, treated wines — file TTB Form 5120.29 through Formulas Online. Wine formula processing runs approximately 3 days median.
Document Cellar Operations
Cellar treatment records under 27 CFR 24 recordkeeping — materials added, quantities, dates, wine lot identification. Records support compliance visits and appellation claim substantiation.
File COLA on TTB Form 5100.31
File through COLAs Online with class/type designation reflecting the wine’s composition. Reference approved formula number for formula-required products.
Preserve Records Under 27 CFR 24
Winery records retention supports TTB compliance visits, appellation claim substantiation, and any state audit response.
Coordinate State Brand Registration
State brand registrations reference the approved COLA. States with specific wine production or additive rules may raise questions on state-side registration for specialty products.
Wine Production Compliance Layers
Wine additive and winemaking practice compliance spans multiple federal and state layers linked by production records.
27 CFR Part 24

Book a DemoWhere Wine Production Compliance Fails
Wine additive and winemaking practice failures cluster around unapproved materials, missed formula approval, and state-specific practice violations.
Unapproved Additive Use
Cellar treatment material or additive used that isn’t within the 27 CFR Part 24 approved framework. Federal compliance risk and product hold potential.
Missed Formula Approval
Specialty wine produced and labeled without formula approval on file under 27 CFR 24.80–24.85. TTB holds the COLA.
State Practice Violation
Chaptalization in a state that prohibits it (California) or specialty additive use in restrictive states. State enforcement follows.
Cellar Records Incomplete
Records don’t adequately document additive use, quantities, or dates. TTB compliance visit response weakened; appellation claims harder to substantiate.
Class/Type Mismatch
COLA class/type designation doesn’t reflect actual wine composition after treatment. Label misleading or requiring correction.
Amelioration Beyond Limits
Water addition exceeding federal amelioration limits without formula treatment. Compliance and quality risk.

Wine Additive and Winemaking Practices — Frequently Asked
27 CFR Part 24 is the federal wine production framework administered by TTB. It covers winemaking practices, approved additives and cellar treatment materials, formula approval requirements for specialty wines, recordkeeping requirements, and bonded wine cellar operations.
Chaptalization is the addition of sugar to grape must or wine to increase eventual alcohol content. It’s a common winemaking practice in cooler climates where grape sugar levels are naturally lower. Federal rules permit chaptalization within specific parameters; California state law prohibits it.
Amelioration is the addition of water (and typically sugar) to grape must or wine to correct high natural sugar or acid levels. Federal amelioration rules under 27 CFR Part 24 have specific parameters governing when and how much water can be added.
Under 27 CFR 24.80–24.85, ‘special natural wine’ is wine produced with added natural flavoring materials, herbs, or other natural botanicals outside the standard grape wine framework. Special natural wines require formula approval on TTB Form 5120.29 before COLA.
Agricultural wine is wine produced from fruits or agricultural products other than grapes — apple wine, pear wine, honey wine (mead), etc. Agricultural wines require formula approval under 27 CFR 24.80–24.85 before COLA and have specific standards of identity.
TTB-approved fining agents include bentonite, egg whites, isinglass, gelatin, PVPP, silica, and others within specified parameters. Each fining agent has specific use guidelines. Consult 27 CFR 24 and TTB Industry Circulars for current approved additive lists.
Sulfur dioxide (SO2) use is permitted within federal limits under 27 CFR 24. Total SO2 in finished wine has federal maximum limits varying by wine type. US limits generally follow international standards though specific limits should be verified against current TTB guidance.
Yes, generally. Fruit wines (apple wine, pear wine, cherry wine, etc.) qualify as ‘agricultural wines’ under 27 CFR 24.80–24.85 and require formula approval before COLA. Wine formula processing runs approximately 3 days median at current TTB queue speeds.
State wine production laws often add to federal 27 CFR 24. California prohibits chaptalization; some states have specific rules on additives or fining agents; some have designated wine production categories with their own additive frameworks. State-by-state analysis is essential for multi-state production.
Cellar treatment records — materials added, quantities, dates, wine lot identification, disposition records, and bonded wine cellar operational records. Records support TTB compliance visits, appellation claim substantiation, and state audits.
TTB Form 5120.29 is the Formula and Process for Wine application, filed through Formulas Online at ttb.gov for wines requiring formula approval under 27 CFR 24.80–24.85.
Approximately 3 days median at current TTB Formulas Online queue speeds (mid-2026). Sample analysis, when required, adds 15 days under TTB’s customer service standard.
