How long do you process peaches when canning?

When canning peaches, the processing time typically depends on the type of jar used. For quart jars, the recommended processing time is about 20-25 minutes in a boiling water bath, while pint jars usually require 15-20 minutes. It's essential to adjust for altitude if you're at a higher elevation, as processing times may need to be increased. Always ensure that the jars are filled properly and that the seals are secure for safe preservation.
