Contract brewing

Brewing your recipe at someone else's brewery. What it costs, why brands do it, and the quality realities.

Contract brewing — paying another brewery to produce your recipes under your brand — is more common than the craft beer industry openly discusses. By some industry estimates, 25-40% of "craft" brand SKUs sold in retail are produced under contract at a different brewery than the brand name suggests.

It's not inherently bad. It's a different business model with different economics, different quality controls, and different risks. Knowing whether to contract-brew is one of the key decisions a beer entrepreneur makes — sometimes before they even consider opening their own brewery.

Who contracts

• Brand-first companies: entrepreneurs who want to launch a beer brand without the $2-10M capital cost of a brewery. The brand owner handles marketing, sales, distribution; the contract brewer handles production.
• Capacity overflow: existing breweries that are running at production capacity and contract their overflow to another brewery. Common during seasonal peaks.
• Geographic expansion: a brewery selling in a new region contracts production there to avoid shipping costs from their home brewery. Sierra Nevada at Mills River (NC), Stone at Berlin, New Belgium at Asheville — versions of this pattern.
• Specialized capacity: a brewery without can lines that contracts the canning portion. A brewery without lager tanks that contracts a pilsner.
• Pivoting brands: a brewery that's closing or scaling down but still has a brand worth keeping in market — contract the production, keep the brand.

The economics

Contract brewing rates vary by region, scale, and specifics, but rough numbers:

Plus you provide:

• Raw ingredients (malt, hops, yeast) — typically $30-60/bbl in cost
• Packaging materials (cans, labels, cartons) — typically $30-50/bbl equivalent
• Federal/state excise tax — you owe this even though they brewed it

Total all-in cost: $140-290/bbl in your hands at the contract brewery. By comparison, brewing in-house with your own facility once paid off runs $40-80/bbl. The contract premium is the price of not owning the brewery.

The legal structure

Contract brewing creates a TTB-registered relationship. The contract brewer holds the federal Brewer's Notice and is responsible for compliance and tax payment. You hold a "Distilled Spirits Plant / Brewery Operations" license as a "non-bonded brand owner" or similar designation depending on state.

Required elements typically:

• Written agreement defining recipes, quality standards, payment terms, exclusivity, brand ownership.
• Recipe ownership clause: who owns the recipe? Critical. If you write a recipe and the contract brewer uses it for other clients later, that's a problem.
• Production minimums and commitments: typical contracts specify minimum monthly or annual production volumes.
• Quality specifications: dissolved oxygen targets, ABV tolerances, color/clarity standards, microbiological standards.
• Termination clauses: what happens when you want out? Cleaner exit clauses than franchise-law distribution agreements.

Most contract brewing arrangements are 1-3 year contracts with renewal options. Some are project-based (single batch agreements). Some are evergreen with notice provisions.

Quality control challenges

The single biggest risk in contract brewing is loss of control over the production process. Your beer is made by someone else, in their facility, on their schedule, by their staff.

The realities:

• You're rarely on-site during brewing. Most contract brewers don't allow client presence during normal production runs.
• You're working with their water profile. Adjustments are possible but require coordination.
• You're working with their yeast house strains or your provided strain — but their fermentation tanks.
• Quality differences batch-to-batch are common even with the same recipe and the same brewer. Recipes that taste great on your homebrew system can taste different at 60 bbl scale.
• You can't make on-the-fly adjustments. If a batch fermentation goes sideways, the response is in the contract brewer's hands, not yours.

Mitigation strategies that work:

• Visit the contract brewery during your first 2-3 batches. Pay extra if necessary.
• Specify quality standards in measurable terms in the contract: ABV ±0.3%, DO < 50 ppb, color in SRM range, hop additions documented per batch.
• Require sensory panel approval before shipping. You taste the batch; if it's not acceptable, you don't pay or you dump.
• Build a "brewing handbook" — your recipe + your process notes + your acceptable variance — that the contract brewer's staff actually reads.
• Send batch samples to an independent lab. Get baseline measurements you can use over time.

The brand-quality perception

Industry attitudes toward contract brewing have softened since 2010 but the perception risk is still real:

• Some retailers / accounts will not carry "gypsy brands" (brands without their own facility). Less common than it was a decade ago, but exists.
• Beer media coverage often includes the contract brewer information. Some publications treat it neutrally; some treat "contract brewed at X for Y" as a downgrade story.
• Consumer attitudes vary widely. Beer geeks often check sources via Untappd or BeerAdvocate. Casual drinkers don't care.
• Some markets (especially the Northeast) are more sensitive. California, Florida, Texas generally less.

Brewers Association (BA) defines "craft brewery" by ownership and production threshold rules. Contract brewers and contract-brewed brands sometimes fall outside BA's craft brewery list, which affects industry-level marketing.

Finding a contract brewer

The market is fragmented. Major contract production facilities:

• Sleeping Giant Brewing (Denver, CO): dedicated contract operation. ~200,000 bbl capacity.
• Brew Hub (Lakeland, FL): ~75,000 bbl. Big enough for distribution-scale brands.
• Stevens Point Brewery (WI): long-running contract operation.
• Two Roads Brewing (CT): contracts a portion of their capacity.
• Numerous regional breweries: any brewery with excess capacity may contract. The "side hustle" contract is more common than the dedicated facility.

Smaller contracts (under 1,000 bbl/year) often happen at local breweries with available tank time. Asking directly is the typical entry point — there's no central marketplace.

Cost considerations beyond per-bbl rate

• Setup costs: recipe development, trial batches, label and TTB approval, COLA registrations.
• Inventory carrying costs: minimum runs of 20-100 bbl means you may sit on inventory longer than you'd like.
• Freight from contract brewer to your distributor/customers: can add $5-15/bbl in shipping costs.
• Premium ingredients: hops markup if contract brewer sources them, or your hops shipping cost if you provide.
• Quality testing: external lab fees for batch verification.

True cost per bbl, all-in, often runs $200-350 for contract-brewed beer in your hands. The math is competitive with running an under-utilized own brewery, but expensive vs a well-run own facility at scale.

Hybrid: contract first, then build

A common pattern: contract brew to validate the brand and build cashflow, then use that cashflow to build an own facility once volume justifies.

• Year 1-2: contract production at 500-2,000 bbl. Focus on brand, sales, market fit.
• Year 3-4: if volume hits 5,000+ bbl with stable demand, consider own brewery.
• Year 5+: own facility, contract brewer becomes overflow capacity only.

This pattern reduces upfront capital and validates the brand before committing $2-5M to a build-out. The risk is brand association with contract production once you transition.

Common mistakes

No quality specifications in the contract. "The beer should be good" is unenforceable. ABV, DO, color, IBU, taste panel results — all measurable, all should be specified.

Single contract brewer dependency. If your contract brewer has equipment failure or quality issues, you're out of beer. Most successful contract brands have a relationship with a backup option.

Underestimating ingredient supply. The contract brewer's hop allocations and malt contracts may not match your needs. Provide your own ingredients or accept their substitutions.

Recipe scale-up problems. A recipe that tastes great on a 5-gallon homebrew system may taste different at 60 bbl scale. Trial batches are essential.

Hiding the contract relationship. The information is publicly available on TTB records. Trying to hide it backfires when it comes out.

Next steps

Contract brewing connects directly to distribution — most contract brands don't self-distribute. See distribution models.

If you're considering your own facility after a contract period, see packaging options — the format you contract-package in often dictates what your own facility needs.
