Canning equipment guides

Last reviewed July 2026.

Every canner we track, plus the background guides. The canner pages answer one question each — does anything beyond the manufacturer stand behind this appliance? — with the authority record quoted and linked. The background guides cover the label claims and equipment distinctions that make the record readable.

Canning Score indexes what NCHFP, USDA and university extension programs have on record about canning equipment, with attribution — we publish no process times and no safety advice. Verdicts describe the state of the authority record for an appliance class, not a guarantee about any jar. For tested recipes and process schedules, use NCHFP (nchfp.uga.edu), the USDA Complete Guide, or your state extension office — or the Seal canning guides, which work food-by-food from the same sources. If an authority publishes new guidance, the page changes — the authority always wins.
