Peaches Ready to Can? Check the Acid Level First
Kitchen and home life · PROBLEM-FIRST
Niagara is Ontario's tender-fruit belt, growing the large majority of the province's peaches, pears, and other tender fruit, and August into September is peak harvest, with field tomatoes running the same window. That harvest is why home canning gear sells this time of year, but not everything from that harvest can go into the same equipment safely. Water bath canning works only for high-acid foods: jams and jellies, most whole fruits including peaches and pears, pickles, and tomatoes with added acid per a tested recipe. Low-acid foods such as plain vegetables, meats, and soups need a pressure canner instead, a genuinely different piece of equipment covered separately on this site, because water bath canning alone does not reach a high enough temperature to make those foods safe. Checking which category a given harvest item falls into, before buying either canner, is the real first step. This section explains that distinction before naming any product.

Who this isn't for
This is not for canning low-acid foods like plain vegetables, meats, or soups; a water bath canner does not reach a high enough temperature to make those foods safe, and using one for them anyway is a genuine food-safety risk, not just a texture or taste issue. That job needs a pressure canner instead, compared separately on this site. It is also not for anyone improvising processing times; always follow a current tested recipe from a reputable canning authority rather than guessing at how long to process a jar.
