How to Find and Vet a Co-Packer

Why co-packer selection is a brand decision

Your co-packer does not just make your product. They are your production partner for the entire life of the brand.

Most founders treat co-packer selection as a logistics decision. Find a facility that can make your product at a price you can afford, sign an agreement, and start production. The founders who build durable brands treat it differently. They treat co-packer selection as a brand partnership decision that will shape their product quality, their production flexibility, their cost structure, and their ability to scale for years to come.

The co-packer relationship is one of the most intimate business relationships in the beverage industry. They know your formula. They know your costs. They have physical custody of your inventory. They control the quality of every unit that goes to market under your brand name. A co-packer who does excellent work and operates with integrity is a genuine competitive advantage. A bad one is a liability that can destroy your brand before consumers ever have a chance to judge the product.

Co-packers are not interchangeable. They have specific capabilities, specific minimum production volumes, specific category expertise, and specific quality standards. A co-packer who excels at producing craft spirits is not necessarily the right choice for a ready-to-drink cocktail. A facility that can run a 500-case minimum may not be the right fit once your brand is doing 5,000 cases a month. Finding the right match requires knowing what you need now and what you will need as you grow.

The vetting process I recommend is comprehensive but not complicated. It has four phases: finding candidates, qualifying them on the phone, visiting the facility, and checking references. Do not skip any phase. A co-packer who refuses a facility visit or cannot provide references from current clients is telling you something important about how they operate.

The non-negotiable standard

Never commit to a co-packer you have not visited in person. A facility that looks professional on a website and a facility that runs a clean, organized, compliant production operation are sometimes very different things. The visit is where you find out which one you are dealing with.

Where to find co-packers

The best co-packer leads come from people who have already worked with them. Start with your network before you start with a directory.

The most reliable co-packer leads come from founders who are already using them. If you know a brand in your category that is producing a quality product at a scale similar to yours, ask them who makes it. Most founders are willing to share a co-packer recommendation, especially if the co-packer has capacity and you are not a direct competitor. That first-hand endorsement is worth more than any directory listing.

Industry associations are a legitimate secondary source. The Brewers Association, the Wine Institute, the Distilled Spirits Council, and various state-level trade associations maintain directories of licensed production facilities that serve as co-packers. These directories do not vet quality, but they give you a starting list of facilities to research and contact.

Beverage brokers and consultants who work with your category often have established relationships with co-packers and can make qualified introductions. A good broker will know which co-packers have available capacity, which have strong QC programs, and which are difficult to work with. That intelligence can compress your search significantly.

Trade shows like the Beverage Forum, the National Restaurant Association show, and category-specific events often include co-packer exhibitors or networking opportunities where you can meet production facilities directly. Meeting a co-packer representative in person at a trade show gives you an early read on their professionalism and communication style before you get into a formal vetting process.

Warm referrals from founders. First choice. Real-world experience from someone who has worked with the facility.

Industry association directories. Good starting list. Requires additional qualification.

Brokers and consultants. Useful for qualified introductions and market intelligence on co-packer reputation.

Trade shows. Good for initial meetings and getting a sense of professionalism before formal vetting.

Vetting on the phone

The first phone call is a qualification call, not a sales call. You are evaluating them as much as they are evaluating you.

The goal of the first phone call with a co-packer is to determine whether they are worth a facility visit. You are trying to answer four questions. Do they have experience in your specific category and product type? Do they have capacity for your projected volumes, both now and 18 months from now? Do they have the quality certifications and regulatory compliance credentials your product requires? And do they communicate clearly and professionally?

Ask specifically about their experience with your category. A co-packer who has produced spirits but never produced RTDs will face a meaningful learning curve on your product. Ask how many brands they currently produce in your category, what volume ranges they handle, and whether they can provide references from current clients in your category specifically.

Ask about minimum order quantities and lead times. If their minimums are significantly above your projected first-year volumes, they are not the right fit for your launch stage. If their lead times are longer than your inventory planning can accommodate, you will run into stockout situations that can damage your distributor relationships. Get specific numbers, not ranges.

Pay attention to how they communicate. Do they return calls promptly? Are they organized in the way they answer questions? Do they ask intelligent questions about your product and your business? A co-packer who is disorganized, slow to respond, or dismissive of your questions during the sales process will be worse once you are a client and your leverage has decreased.

What the phone call is really telling you

You are not just gathering information. You are evaluating whether this is a company you can build a long-term relationship with. A co-packer who is enthusiastic, organized, and asks smart questions about your brand is signaling something about their culture. One who seems indifferent or talks only about their own capabilities without asking about your needs is signaling something else.

The facility visit and references

The visit and the references are where you confirm or contradict everything you heard on the phone.

The facility visit should be treated as a structured inspection, not a tour. Come with a checklist. Is the facility clean and organized? Is product stored properly? Are employees following safety and sanitation protocols? Are allergen controls in place if relevant to your product? Is the QC lab functional and properly equipped? Is the equipment appropriate for your product type and volume? Does the facility have current regulatory compliance certifications posted and available for review?

While you are touring, ask to see the production line for a product similar to yours if one is running. Watching a production run tells you more about a co-packer's operational quality than any conversation. Notice whether the line runs smoothly, whether the staff is trained and attentive, and whether the QC checks are actually being performed rather than just described.

Ask to meet the people who will actually work on your account. Not just the sales representative, but the production manager, the QC lead, and if possible, the floor supervisor for your product type. These are the people whose competence will determine the quality of your product every day. A strong sales team at a co-packer with weak production management is not a good partnership.

After the visit, check every reference they provided. Ask specifically about product quality consistency, communication during problems, how they handled packaging errors or quality failures, whether they hit agreed timelines, and whether the client would use them again. A reference who gives enthusiastic but vague answers is less useful than one who can speak specifically about specific situations and how the co-packer handled them.

The bottom line

Your co-packer selection will shape your brand's quality, your cost structure, and your ability to execute for years. Do the full process. Get warm referrals, qualify on the phone, visit in person, and check every reference. The extra time you spend in selection is nothing compared to the time and money you will lose working with the wrong facility.
