Contract Brewing

What Is Contract Brewing

Contract brewing means hiring another brewery (the host) to produce beer under your brand using your recipes. You own the brand and handle marketing, sales, and distribution. The host brewery provides equipment, labor, and sometimes ingredients.

This model allows you to launch a beer brand without the massive capital investment of building a brewery. Several well-known craft brands started as contract brewers, including Samuel Adams and Brooklyn Brewery.

Models and Variations

Pure Contract

You provide the recipe and specifications. The host brewery produces, packages, and may warehouse the beer. You have minimal involvement in production. Lowest cost, least control.

You operate as a separate legal brewery within the host's facility, using their equipment under a shared-space agreement. You maintain your own TTB Brewer's Notice, manage your own production, and have full control of the brewing process. More complex legally but provides greater quality control and allows you to build brewing credibility.

Gypsy Brewing

A term (borrowed from European tradition) for itinerant brewers who travel between host facilities, personally brewing their recipes on different systems. More hands-on than pure contract, but without a fixed location.

Finding a Host Brewery

Capacity — the host needs unused capacity. Many breweries built for growth have excess fermentation space. Compatibility — their equipment should match your recipe requirements. A brewery with no lager fermentation cannot produce your Czech Pils. Quality standards — visit the facility. Evaluate their cleanliness, QC procedures, and the quality of their own beers. Your beer's quality ceiling is set by the host's standards. Location — proximity to your market reduces freight costs. Proximity to you enables oversight.

Quality Control Challenges

The fundamental challenge of contract brewing: maintaining quality when you do not control the production environment.

Be present — attend brew days whenever possible. Taste beer at every stage. Build a relationship with the head brewer. Written specifications — provide detailed recipe documents including mash temperatures, hop addition timing, fermentation schedule, and sensory targets. Lab analysis — request analytical data (OG, FG, pH, DO, IBU) for every batch. Establish reject criteria. Sensory approval — taste-approve every batch before release. Do not ship beer you would not serve in your own taproom.

Economics

Per-barrel cost — $60-120 per barrel for production only. Ingredients, packaging, and logistics are additional. Total landed cost: $150-250 per barrel depending on complexity. Minimum volumes — most hosts require minimum batch sizes (7-15 barrels) and minimum annual volumes. Payment terms — typically 50% deposit on order, balance on delivery. Some hosts offer net-30 terms for established relationships.

Transition Planning

If your goal is eventually owning your own brewery, use the contract phase to:

Build brand recognition and a loyal customer base. Establish distribution relationships. Validate recipes and refine production processes. Accumulate capital and track record for lender/investor conversations. The transition from contract to own-facility typically happens at 2,000-5,000 barrels annually, where the economics of ownership become favorable.
