What a co-packer actually is
A co-packer is a manufacturing facility that produces your product for you. The terms co-packer, co-manufacturer, and contract manufacturer all mean the same thing in beverage: a third-party plant that owns the equipment, the certifications, and the labor, and runs your formula on your behalf. You own the brand and the recipe; they own the line.
For almost every new beverage brand, co-packing is how you get made. Building your own facility costs millions and takes years. A co-packer lets you launch with a fraction of the capital, which is exactly why choosing the right one matters so much. You are handing the physical reality of your product to someone else.
Depending on your category, you'll hear the same model called beverage co-packing, contract bottling, contract manufacturing, or small-batch beverage co-packing. The terminology shifts by product type, but the core relationship is the same: you own the brand and the specifications; the production partner owns the facility, the labor, and the equipment.
A note from Jamie
Early founders often walk into the first co-packer call assuming the facility is trying to win their business. At small launch volumes, the dynamic is more balanced: you're evaluating the co-packer, but the co-packer is also deciding whether your run fits their line, schedule, documentation standard, and economics. Founders who understand that come prepared, and tend to get better answers.
The six-criteria evaluation framework
Score every co-packer on the same six dimensions. The point isn't to find a perfect facility. It's to know exactly where each candidate is strong and where you're accepting a trade-off. Our downloadable scorecard turns this into a weighted number you can compare across candidates.
| Criterion | The question it answers |
|---|---|
| Capability | Do they know how to make your kind of product? (expertise + track record) |
| Capacity | Can they run your volume now, and as you grow? |
| Certifications | Do they hold the food-safety and program certifications your retailers require? |
| Equipment | Do the specific machines on their floor physically run your format and process? |
| Geography | Where are they, and what does that do to your freight and oversight? |
| Performance | Do they deliver on time, in spec, with clean documentation? |
Capability vs. Equipment: the distinction that trips founders up
These two get confused constantly, so be precise. Capability is whether the co-packer knows how to make your kind of product: the expertise, the process know-how, and the track record. Equipment is whether the specific machines on their floor can physically run your format and process. A facility can have deep capability in your category and still lack the exact filler or container line you need. The reverse happens too: the right machines, but no experience with your process. In practice, experienced operators usually evaluate the two together, since a co-packer with real capability in your category almost always has the equipment to match. Keeping them distinct on paper just helps you spot exactly where a gap is.
1. Capability
What it means: whether the co-packer has the expertise and process know-how to make your category of beverage, and whether they have actually done it before. Capability is about knowledge and track record, not the machines themselves (that is Equipment, next). A carbonated functional soda, a cold-pressed juice, a dairy or plant-protein shake, a live-culture probiotic, a botanical tonic, and a CBD or functional beverage each demand different process competence even when the filling machine looks the same.
What to ask: What beverage categories have you actually produced? Have you made a product with my process and ingredient complexity, like live cultures, a high-protein emulsion, or functional actives dosed to a target? What is the closest product to mine you have run?
Documents to request: a list of the product categories and processes they actually produce (not a line sheet, which describes equipment), plus a reference from a comparable product.
What a good answer sounds like: "We run three SKUs almost identical to yours in process and ingredients. Here is the category, here is how we handle that process, and here is a client you can call."
The call: capability is hard to teach and slow to build. If a co-packer has never made your category or run your process, treat that as a major risk even when everything else looks great. Weight this criterion high.
Questions to ask about capability
- What beverage categories and processes have you actually produced?
- Have you produced a product with my ingredient complexity before?
- What's a product you've run that's closest to mine, and can I call that client?
- Are there formulations or processes you won't take?
2. Capacity
What it means: whether they can run your volume, both your first small run and your growth, and where your run sits in their schedule. This is where minimum order quantities (MOQs) live.
What to ask: What's your MOQ per SKU? What's your current lead time? How far out is your production calendar booked?
The numbers founders ask about: most beverage co-packers run minimums in the range of 10,000 to 50,000 units per SKU. Smaller specialty co-packers go lower; large plants go much higher. Underestimate your MOQ and you're disqualified. Overestimate and you tie up cash in inventory you can't sell fast enough.
Documents to request: current MOQ schedule, lead-time expectations, line availability, changeover or cleaning-fee policy, and any volume-based price breaks.
What a good answer sounds like: "Our MOQ is X units per SKU, we're booked about Y weeks out, and your first run would fit these windows. As you grow, we can support up to Z runs a quarter before we'd need to revisit scheduling."
The call: if the MOQ forces a run bigger than the demand you can actually prove, keep looking. A great facility you can't afford to fill is the wrong facility.
Common founder mistake
Chasing the lowest per-unit price by committing to a bigger run than your sales can absorb. A warehouse full of product with a 12-month shelf life is not an asset. It's tied-up cash with an expiration date. Match your first run to demand you can actually prove, not to the price break.
3. Certifications
What it means: the food-safety and quality programs a co-packer holds. These aren't bureaucratic box-checks. Most retailers require specific certifications before they'll put you on shelf, so your co-packer's certifications gate your distribution.
What to ask: What certifications do you hold? Are you GFSI-benchmarked (SQF, BRCGS)? When was your last third-party audit, and can I see the certificate?
Documents to request: current certification certificates, the date and scoring of the most recent audit, and their HACCP or food-safety plan summary.
What a good answer sounds like: "We're SQF certified, here's our current certificate and audit score, and here's the date of our next audit."
The call: certifications are pass/fail for the retailers you're targeting. If your target retailer requires SQF and the co-packer doesn't have it, that's disqualifying no matter how good the price is.
Documents to request before you sign
- Current food-safety certification certificate (and audit score)
- Certificate of insurance with adequate product-liability coverage
- A sample batch record and Certificate of Analysis (COA)
- A sample finished-product spec sheet
- Two or three brand references they currently run
4. Equipment
What it means: the specific machines on their floor, and whether they physically match your product's format, fill, and process. Capability is "do they know how." Equipment is "do they have the right machine." This is the criterion you confirm with your own eyes on the facility visit, because a co-packer can be capable in your category and still be missing the one machine your product actually needs.
A beverage line is a chain of machines. Walk it station by station and confirm each one fits your product. Here is the exhaustive list of what to look at and what to ask about each.
| Equipment | What it does | What to ask / criteria |
|---|---|---|
| Blending & batching tanks | Mix, dissolve, and hydrate your formula before filling. | Tank size in gallons and how it maps to your batch; jacketed for heating/cooling; high-shear capability for powders, gums, or emulsions; agitation for suspensions. Criteria: tank size suits your run and can hold your viscosity and temperature. |
| Filler (the core machine) | Meters product into the container. The single most important machine to match. | Which fill technology: gravity, counter-pressure (for carbonated), piston/volumetric (for viscous or pulpy), hot-fill, cold-fill, or aseptic. Fill accuracy and fill temperature. Criteria: the fill type matches your product and process exactly. |
| Carbonation / CO2 system | Carbonates sparkling products to a target level. | Carbonation range (volumes of CO2) and consistency run to run. Criteria: can reliably hit your target carbonation for a sparkling product. |
| Thermal processing | Makes the product safe and shelf-stable: tunnel or flash (HTST) pasteurizer, hot-fill, retort, UHT, or HPP (high-pressure processing, non-thermal). | Which process, the time and temperature, and whether it suits your ingredients' heat sensitivity. Criteria: the process matches your shelf-life target and protects your actives. (See our aseptic guide for the heat-sensitive case.) |
| Container handling | Feeds, rinses, and conveys your container through the line. | Which containers they run (aluminum can in standard, slim, or sleek; glass bottle; PET; pouch; carton; keg) and which sizes. Criteria: they run your exact format and size, or will tool up for it. |
| Seamer / capper / closure | Seals the container. Cans use a seamer; bottles use a crown, screw, or ROPP capper; pouches and cartons use heat or form-fill-seal. | The closure type for your format, plus induction sealing if your product needs a tamper-evident seal. Criteria: the closure matches your package. |
| Labeling / decoration | Applies your label or decoration. | Which label type: pressure-sensitive, shrink sleeve, wet-glue, or direct print. Application speed. Criteria: supports your label decoration without a separate vendor. |
| Coding / date marking | Prints lot and date codes for traceability and recall. | Inkjet or laser, and code placement. Criteria: meets retailer traceability and recall requirements. |
| Water treatment | Filters and treats incoming water, which is often your largest ingredient. | Source water plus treatment: carbon filtration, reverse osmosis, UV. Criteria: water quality matches your formula spec. |
| Secondary packaging | Turns filled units into retail-ready cases and pallets. | Case packer, tray or shrink wrap, multipack (rings, PakTech), palletizer. Criteria: matches your retail pack-out and case configuration. |
| CIP (clean-in-place) & changeover | Cleans lines between runs to prevent cross-contamination. | Allergen and flavor changeover protocol; dedicated vs. shared lines. Criteria: prevents cross-contact for your allergen profile. |
| Line speed / throughput | How fast the line runs your format, in units per minute. | Cans or bottles per minute on your specific format. Criteria: fast enough to make your run cost-efficient at your volume. |
What a good answer sounds like: specifics, not reassurance. Real line speeds, container specs, batch sizes, and a standing invitation to walk the floor.
The call: some equipment gaps are fixable (a co-packer may tool up for your container) and some are not (they don't run aseptic and won't buy a line for one client). Confirm your must-haves on the visit. If your product needs a process they simply don't have, that's disqualifying unless they'll invest in it.
A note from Jamie
Co-packers quote differently depending on how much of the ingredient work they take on. A run where the co-packer sources, stages, and batches a dozen raw ingredients is a different quote than one where you supply materials ready for them to run. Before you compare two quotes, make sure they assume the same scope of work. Otherwise you're comparing numbers that don't mean the same thing.
5. Geography
What it means: where the facility sits relative to your ingredients, your customers, and you. Geography drives freight cost (a real line in your COGS), product freshness, and how easily you can be on-site for a run.
What to ask: Where will my product ship from? What does inbound and outbound freight look like for my lanes?
Documents to request: estimated freight lanes, receiving requirements, storage rates if finished goods stay on-site, and any preferred freight or warehousing partners.
What a good answer sounds like: "We ship to your target region regularly, we can receive from your ingredient and packaging suppliers, and here's what inbound and outbound freight usually runs for brands with a similar footprint."
The call: geography is a trade-off, not pass/fail. A stronger co-packer farther away usually beats a weaker one nearby. Weight it low unless freight or freshness is make-or-break for your product.
6. Performance
What it means: the track record. Do they hit dates, hold spec, and document cleanly? This is the hardest criterion to assess from the outside, which is exactly why references and a test run matter.
What to ask the co-packer: What's your on-time rate? How do you handle a run that comes out of spec? Can I start with a small test run before committing to volume?
What to ask their references: Did they hit your timelines? What happened when something went wrong? Would you run with them again?
Documents to request: a sample batch record, a sample COA, a reference list, on-time production history if they track it, and their deviation or corrective-action process.
What a good answer sounds like: "Here are two current references, a sample batch record, and an example of how we handled an out-of-spec run, including who makes the final call when product is outside target."
The call: you can't fully verify performance until you've run with them, which is why a small test run and real reference calls carry the most weight here. Lukewarm references are a quiet no.
How to decide
- Sign when a co-packer scores well on capability, certifications, and performance, and the trade-offs (geography, MOQ) are ones you can live with.
- Keep looking when capability is a stretch, the MOQ forces a run bigger than your demand, or references are lukewarm.
- Walk away when you hit any of the red flags below, regardless of how good the price is.
What a co-packer quote actually includes
Co-packer quotes are hard to compare because they don't always cover the same scope of work. One facility quotes only the production run. Another bundles in batching, ingredient handling, packaging setup, storage, quality documentation, or line trials. Before you compare price, make sure you understand what each quote actually includes.
Price isn't one of the six scoring criteria, and that's deliberate. Score quality on the six, then weigh that score against the quoted price. The goal is the best quality-for-price, not the lowest number on the page. The figure that anchors most founders' budgets is the per-unit production cost the co-packer quotes against your specific product and run size. Most co-packers don't charge a separate onboarding fee; the few that do keep it modest. The downloadable Scorecard includes a commercial-terms worksheet to capture the numbers, per candidate, right next to the quality score.
Common components of a co-packer quote:
- Setup or onboarding fees (if any): some facilities charge a one-time cost to bring your product into their system, but many don't.
- Pilot or test-run fees: small-scale production before full commercial volume.
- Tolling or per-unit production cost: what the facility charges to run each unit or case.
- Ingredient and packaging responsibility: whether you buy inputs directly or the co-packer procures them.
- Changeover or cleaning fees: especially when allergens, colors, flavors, or formats change.
- Storage or warehousing: charges if raw materials or finished goods sit at the facility.
- Quality documentation: batch records, COAs, retains, and post-run reporting.
A note from Jamie
The cheapest quote is rarely the cheapest run. The right comparison isn't price per unit alone. It's price per unit, plus risk, plus how much work the co-packer is actually taking off your plate. A quote that excludes ingredient procurement and documentation can look 20% cheaper and cost you far more once you're doing that work yourself.
Red flags that should make you walk away
Some signals are bad enough to override everything else. Price never buys back any of these.
Walk away if…
- They won't let you visit the facility, or keep deferring the visit.
- They can't (or won't) produce a current certification certificate or a sample COA.
- They're vague about MOQs, lead times, or pricing structure after repeated asks.
- The contract claims any ownership of your formula, recipe, or IP.
- Communication is already slow or evasive during the sales stage. It does not improve once you've signed.
- References are unwilling to talk, or quietly hesitant when they do.
How long the evaluation takes
Expect the evaluation to take weeks, not days. A real process means building a shortlist, screening for fit, requesting documents, visiting facilities, checking references, and negotiating commercial terms. Rushing it is usually slower in the long run. Switching co-packers after launch is far more disruptive than choosing carefully up front.
As a rough planning guide, founders often spend about four weeks on evaluation, then reach a first production run roughly 8 to 12 weeks after a signed agreement and approved formula, assuming ingredients, packaging, and approvals are ready. Specialty processes like aseptic filling take longer to onboard. Confirm the real timeline with each co-packer; these ranges vary widely by category and capacity.
After you sign: onboarding to first run
Selecting the co-packer is the start, not the finish. Between signing and your first run:
- Sign the MSA: the Master Services Agreement covering pricing, MOQs, lead times, quality responsibilities, liability, and (critically) your ownership of the formula and IP.
- Create the production specification package, the documents the co-packer produces against: ingredient specs, processing targets, packaging requirements, allergen information, QC checks, batch documentation, and finished-product standards.
- Stage the supply chain: get ingredients and packaging on the floor, in spec, with documentation in order.
- Run a first-article approval: a small confirmation run before full volume, so you catch problems while they're cheap.
Common founder mistake
Assuming the formula that worked on the bench will run unchanged at scale. It often won't. Ingredient sourcing, batch behavior, and line constraints can all force adjustments. Expect a first-article step, and budget time for it. A formula that needs a tweak at the co-packer is normal; discovering it during a full production run is expensive.
When to bring in operational help
Running this evaluation yourself is absolutely doable. That's why we published the whole framework. But it's a lot to carry while you're also building a brand, raising money, and selling. Some founders want a partner to run the search, manage the relationship, and stand at the line for production. That's the operations layer JAI provides. More on that below.
