Ranked #2 in Best Pressure Cookers
All-American 921 Cast Aluminum Pressure Canner (21.5-Quart)4.7
$500The 921 is the canning workhorse American homesteaders treat as a generational tool. Its patented metal-to-metal seal eliminates the single most common failure point on pressure canners — the rubber gasket — and the heavy cast aluminum body with triple bayonet clamps maintains pressure with virtually no siphoning during long quart-jar processing. At 21.5 quarts it hits the practical sweet spot for batch canning (19 pints or 7 quarts), and All-American's lifetime warranty plus 30+ year owner reports back the heirloom-purchase framing.
Strengths
- — Patented metal-to-metal sealing system — no rubber gasket to dry out, replace, or fail in service
- — Built in Wisconsin from heavy cast aluminum with a lifetime warranty and 30+ year owner reports
- — 21.5-quart capacity processes 19 pint jars or 7 quart jars in a single load — the canning standard
Watch-outs
- — Heavy — 17.75 lb empty, well over 40 lb fully loaded with jars and water
- — Premium price puts it well above gasket-sealed canners in the same capacity class
- — Lid can be hard to remove after a long process without occasional oiling of the sealing surface
