The egg whites you use to clarify a batch, the isinglass that drops the haze out of a beer, the casein that smooths a wine: to a producer these are routine processing tools. To a guest with a food allergy, they are eggs, fish, and milk. Federal regulators are paying closer attention to that gap, and a proposed rule would eventually require Tennessee producers to spell it out on the label.
There is no deadline bearing down here. The rule is still proposed, and even after it is finalized, producers would have years to comply. But this is exactly the kind of change worth understanding while it is calm, so the eventual label and recipe decisions are made on purpose rather than under a clock. Here is where things stand and what a brewery, distillery, winery, or cidery can do now.
Where the rule stands today
Allergen labeling on alcohol is governed federally by the Alcohol and Tobacco Tax and Trade Bureau (TTB), the agency that approves the labels on wine, distilled spirits, and malt beverages. Under the current rules, declaring major food allergens on an alcohol label is voluntary. A producer can choose to disclose them, but nothing forces it yet.
That is the part poised to change. In January 2025, TTB published a proposed rule (Notice No. 238) that would make allergen disclosure mandatory on wine, spirits, and malt beverage labels. The public comment period ran into the summer and closed on August 15, 2025. The proposal is not final, and there is no published effective date. When TTB does issue a final rule, it has proposed giving producers five years from that date to bring labels into compliance. So the runway is long, but the direction is clear.
The catch hiding in “voluntary”
Voluntary does not mean simple. Under the current framework, if a producer chooses to declare any major food allergen on a label, it has to declare all of them, including allergens introduced by fining and processing agents, not just the ones in the finished recipe. TTB reinforced this in guidance circulated in 2026: a “Contains” statement has to be complete. You cannot list the wheat and stay quiet about the isinglass.
For a producer, that is the trap worth seeing early. A well-meaning label that names one allergen but misses a processing aid is not a partial disclosure. It can be an inaccurate one. That is why the decision to label at all should be made with a full read of everything that touches the batch.
The allergens that ride in on your process
The nine major food allergens recognized under federal law are milk, eggs, fish, crustacean shellfish, tree nuts, wheat, peanuts, soybeans, and sesame. Most producers think first about ingredients. The harder ones to track are the agents used to clarify, fine, filter, or stabilize a batch, which can carry an allergen even when it is mostly removed before bottling. The usual suspects:
- Egg whites or albumen, used to fine red wine and some spirits, count as eggs.
- Isinglass, a clarifying agent derived from fish, counts as fish.
- Casein, a milk protein used to fine wine, counts as milk.
- Wheat and other grains can show up through the base recipe in beer and certain spirits.
None of these are exotic. They are standard tools in a working cellar or brewhouse, which is the point: the allergens most likely to be missed are the ones that come from how a product is made, not from what is on the recipe card.
What the proposed rule would actually require
If the proposal is finalized in something close to its current form, the voluntary choice goes away. Producers would have to disclose the major food allergens used in production, including those from fining and processing agents, on the label of every covered product. The disclosure takes the form of a “Contains” statement that names the food source, for example eggs, fish, or milk. The proposed five-year compliance window is meant to give the industry time to work through label redesigns and supplier records before the requirement takes hold.
Worth keeping in mind: a proposed rule can change before it is final, and TTB received substantial industry comment. The shape of the final requirement, and its timing, are not locked. That uncertainty is a reason to prepare flexibly, not a reason to wait until the rule is done.
Why a quiet rule is worth handling early
Five years sounds like plenty of time, and it is, until it is a label redesign across an entire portfolio with a finalized rule already in effect. A few things make the runway shorter than it looks:
Labels turn over slowly. Artwork, printing runs, and TTB label approvals all take time, and a mandatory allergen line may touch every SKU you make.
Supplier records have to back up the label. To declare allergens accurately, or to confidently say a batch is free of them, you need clean documentation on the fining and processing agents your suppliers provide.
Reformulation is on the table. Several common fining agents have non-allergenic substitutes, such as bentonite, activated carbon, or pea-based proteins. A producer who would rather keep allergens off the label entirely has time to test alternatives now, while there is no pressure.
Handled early, this is a paperwork-and-planning exercise. Handled late, it becomes a portfolio-wide scramble against a federal deadline.
A short pass to run now
For any Tennessee producer that bottles, cans, or kegs under its own label:
- Map your process. List every fining, filtering, and processing agent in use, not just the recipe ingredients, and flag anything tied to one of the nine major allergens.
- Pull your supplier records. Confirm you can document what is in the agents you buy, and what is in your finished product, in writing.
- Audit your current labels. If you already make any voluntary allergen claim, check that it accounts for processing aids too, so today’s label is accurate under today’s rules.
- Decide your direction. For each product, the choice is roughly: disclose accurately, or reformulate toward non-allergenic agents so there is nothing to disclose. Make that call deliberately.
- Build it into your label cycle. Fold allergen review into the next redesign or new-product approval rather than treating it as a one-time project later.
Where BevLaw Group fits
The label is the visible piece. The work that keeps it defensible sits behind it: reading your supplier and ingredient agreements so the documentation actually supports what you put on the bottle, reviewing label copy and TTB submissions before they go out, weighing whether a “Contains” statement or a reformulation is the smarter path for a given product, and tracking where a proposed rule like this one lands so you are not the last to know. As the ongoing hospitality attorney for breweries, distilleries, wineries, and the venues that pour them across Tennessee, BevLaw Group handles that work on a flat monthly fee, so a rule that is years from final is something you can plan around instead of react to.
If you label your own products and want to know where you stand before this rule firms up, a short conversation now is the easiest version of this problem.
