University of Minnesota Extension guidance for preparing and pressure-canning beef, chicken, or turkey stock.
Source schedule (University of Minnesota Extension, reviewed 2015): dial-gauge pressure canner — pints 20 minutes at 11 PSI; quarts 25 minutes at 11 PSI. Weighted-gauge pressure canner — pints 20 minutes at 15 PSI; quarts 25 minutes at 15 PSI. The source also notes altitude affects pressure requirements. Because canning guidance can be revised, verify the current USDA/NCHFP or Extension processing schedule for your altitude and canner type before use.
