Hot-pack time. Raw-packed peaches need a longer tested time, so follow your recipe.

Times and pressures are restated from the National Center for Home Food Preservation and the USDA Complete Guide to Home Canning, in our own words. They are the same table Putby's app uses; a test in the app fails if the two ever disagree. Altitude schedule: Putby adds minutes to boiling-water processes in five steps up to 10,000 ft; at the higher steps that can be a few minutes longer than a food's own USDA altitude table, never shorter. If your tested recipe gives a longer time, use the recipe's time. Last reviewed 2026-10-16.
