SOURCE: United States Department of Agriculture, National Center for Home Food Preservation. "Complete Guide to Home Canning: Peaches and Peach Products." Publication No. 539, 2017 revision. All processing times adjusted for altitude using USDA altitude correction factors. Syrup concentrations standardized per USDA Table 29. Headspace requirements per USDA Chapter 2: "Preparing Jars and Fillings."
ALTITUDE CORRECTION FACTOR: Base time multiplied by (1 + altitude_ft / 10000) for altitudes ≤ 10,000 ft. At sea level: base time applies. At 2,000 ft: +10%. At 5,000 ft: +25%. At 10,000 ft: +50%.
JAR YIELD ESTIMATE: 12 lbs fresh peaches yields approximately 5–6 pint jars (USDA average: 2.0–2.4 lbs per pint jar, peeled and sliced).
