4 facilities, and only 1 names a figure: Ginseng UP in Worcester, from 1,000 cases. That is not a small-batch number, and the two routes that were the small-batch answer on this page — a mobile canner and a Lowell co-packer — both have websites that stopped resolving in August 2026.
Alphabetical. One of the 4 entries carries a verification caveat worth reading before you plan around it: its own domain no longer answers.
| Facility | City | Minimum run | Formats | Alcohol | Notes |
|---|---|---|---|---|---|
| Dorchester Brewing Company | Boston | Not published | Can, Glass, Keg | Yes | Verify directly before relying on this entry. Described by trade press as Boston's first contract brewery: a 25,000 sq ft facility on a 30-barrel system, producing for around fifteen regional and national brands. Our confidence here is lower than for the rest of this page. |
| Ginseng Up Corporation | Worcester | 1,000 cases | Glass, PET, Can | — | Worcester. Thirty-nine years in business and vertically integrated: its own brand, contract manufacturing, private label and concentrates, from its own bottling plant. The only facility in the state to name a figure — low MOQs, starting from as low as 1,000 cases — a floor rather than a hard threshold. Organic, non-GMO, kosher and gluten free. The co-packing offer lives on their corporate site, not the brand one — where a client puts their name to it: GuS Sodas say they have bottled there since 2003. |
| M.S. Walker | Boston | Not published | Glass, PET | Yes | Boston, with the head office in Norwood. A family-owned spirits bottler that is also a national distributor — an unusual combination. In their words they take on project small and large, ranging from private label and control brand development to large scale contract bottling, with in-house recipe development and hundreds of pre-approved formulas. Eighteen mould shapes in PET and glass, 100 ml to 1.75 L; organic, EcoCert and vegan certified. One condition worth knowing before you start: all products will say “Bottled in Boston”. No minimum published — what they publish is capacity, 59 tanks and 160 bottles a minute, which answers a different question. |
| Merrimack Beverage Copacking | Lowell | Not published | Can, Can sleek, Can 16 oz | Yes | Co-packing and contract brewing of beer and non-alcoholic sodas, serving the Northeast and Mid-Atlantic, with formulation help, sourcing and label design. Their domain returned a 404 on 30 August 2026 — the details here come from earlier records, not a page we could read that day. Confirm they are trading before you plan around them. |
Boston is the largest city in New England and the hub of one of the country's densest craft brewing scenes. It has exactly one contract brewery we could verify: Dorchester Brewing, running a 30-barrel system for around fifteen brands. Everything else in the state sits outside the city — Lowell, Worcester and, for M.S. Walker’s head office, Norwood.
The 4 split cleanly by what they actually do. Two are alcohol routes (Dorchester for beer, M.S. Walker for spirits). One is a long-established non-alcoholic bottler (Ginseng Up, 39 years). One — Merrimack, in Lowell — is the only fixed plant here positioned squarely at brands that need formulation help and label design as well as filling.
The practical read: Massachusetts is well covered for beer and spirits, thin for everything else, and silent on volume across the board.
Across the 234 facilities we track nationally, 38 publish a minimum — about one in six. Massachusetts publishes 1 of 4, close to Michigan and ahead of North Carolina, which publishes nothing at all.
The state is also served by a mobile canner based elsewhere — Anvil Craft Services covers Massachusetts from Connecticut. Black Diamond Canning, the only mobile operator based in the state, has closed. For a brand already brewing or fermenting on site, a visiting truck is still a way to get packaged without negotiating a plant minimum — but there is no longer one based here.
One of these carries a verification caveat — a domain that returned a 404 on 30 August 2026. We list it because it appears to be operating, not because we can vouch for the detail.
Dorchester Brewing is our lowest-confidence entry on this page. The trade press describes it as Boston's first contract brewery, but we could not confirm the current contract offer on their own site. If it's your first choice on geography, confirm the basics by phone before building a plan around it.
Black Diamond Canning has closed. The mobile canner based in Marblehead stopped resolving its domain in August 2026 and the closure was confirmed to us. We have removed it from the table rather than leave a route that no longer exists — a closure is a finding, not a gap.
Tell us the product and the volume. Only 1 of these publishes a minimum, and it starts at 1,000 cases — if your first run is smaller, this is the fastest way to find out who will take it, and we'll look at neighbouring states too.
