H and H Coffee

Dedicated to the history of the Hoffmann-Hayman Coffee Co. founded 1899 in San Antonio, Texas.

National canmaker, incorporated 1901; traded as Canco. Supplied coffee tins for H&H lines including Master Chef. Distinct from New Orleans Can Company (the 1923 cooperative-ad partner for tea/spice/pail lithography). American Can became Primerica in 1986 and exited the can business; by then the H&H brand had been absorbed by Continental Coffee of Chicago (1962).

Canco as both canmaker and equipment maker

American Can sold not just finished tins but also the can seamers used to seal them on the customer’s production floor. The standard product line was the Canco Model 06 (small-format) and Canco Model 08 (large-format):

Model Diameter range Capacity Type
Canco 06 202–404 (2⅛”–4¼”) — Single or multi-head
Canco 06-422 300 (3”) High-speed —
Canco 08 502–603 (5⅛”–6³⁄₁₆”) Up to 30 cans/min Atmospheric or vacuum (08C)

Can diameter uses a double-digit notation: XYY = X whole inches + YY/16ths. The 307 code (3⁷⁄₁₆”) is the classic 1-lb coffee can; 502 (5⅛”) is the standard 3-lb coffee can diameter.

H&H factory seamer requirements

H&H’s documented tin sizes (H&H Blend: ½ lb, 1 lb, 2.5 lb, 3 lb; Master Chef: 1 lb, 2 lb, 3 lb) span at least two seamer format classes:

  • 3-lb tins → Canco 08, 502 diameter tooling — the surviving eBay example (item 123924453162) is an atmospheric Model 08 with 502 tooling, seller-refurbished; illustrates what the machine class looks like.
  • 1-lb tins → Canco 06, 307 or 401 diameter tooling — the smaller-format seamer for standard 1-lb cans.
  • ½-lb tins → Canco 06, 211 or 300 diameter tooling.

A complete H&H production run at Delaware Street required at minimum two seamer models.

Vacuum vs. atmospheric

The Canco 08C is the vacuum variant. If H&H vacuum-packed their tin-line coffees (as they did their Crystalvac glass jars), the 601 Delaware plant would have housed 08C vacuum seamers rather than (or alongside) atmospheric 08s. The 601 Delaware building shows structural evidence of a heavy compressor load (45° shear cracks in RC beams, I-beam retrofits) consistent with vacuum-packing compressor weight and vibration — physical corroboration that some form of vacuum equipment was in operation. See 601 Delaware Street Plant for the structural analysis.

Melvina Can Machinery as research resource

Melvina Can Machinery (Queensbury NY, est. 1934) rebuilds Canco seamers and stocks parts. They maintain a live inventory of Canco 06 and 08 machines across the full 202–603 diameter range, with videos demonstrating operation. As a third-generation firm operating since the same era as H&H’s Delaware Street plant, they are the most practical living reference for how these machines worked and what they weighed.

Physical evidence — Canco imprints on H&H artifacts

Confirmed (2026-05-24): Canco imprints are physically present on H&H coffee can artifacts in the collection. The imprint is the manufacturer’s mark stamped into the base or lid of the can during production — direct physical evidence that American Can Company manufactured the tins, not just supplied them through a distributor.

Specific cans confirmed to carry a Canco mark and the imprint text/location have not yet been documented in the artifact records. This should be photographed and transcribed to the individual artifact pages (see below).

Priority documentation task: For each can in the collection, photograph the base and lid; transcribe any Canco mark (typically includes “CANCO”, a plant code, and a date code). Date codes would directly date when each tin was manufactured, helping to anchor label-era timelines.

Open questions

  • Which specific artifact records document the Canco base/lid mark? Physical inspection confirms the mark exists; it needs to be photographed and transcribed into the artifact pages for HH-COLL-0000-0008 (Master Chef 3 lb), HH-COLL-2008-0001 (Master Chef 1 lb), and the H&H Blend tins.
  • Did H&H run atmospheric or vacuum tin seaming (or both)? Determines whether the 08 or 08C variant was on the floor.
  • When did the American Can supply relationship begin and end? Did it displace New Orleans Can Company or serve a different format tier? Do the date codes on the Canco-marked tins help bound this?
  • Are any Canco seamers still at 601 Delaware or traceable through the 1962–1972 disposition chain?
