Glass Jam Jars

There are many acceptable sizes of jam jars, so the best capacity for your product depends on your ideal portion and intended application. Small jam jars and mini jelly jars– less than 4 oz– are excellent for small serving sizes, often used with charcuterie boards, brunch items, or samples. Common store-bought capacities are 4 oz, half pint (8 oz), 12 oz, and pint (16 oz). Quart jars (32 oz) make for great large jam jars.

The best canning jars for jam have wide mouths and are made of tempered glass to withstand the high temperature of hot fill jams, jellies, and alike. Canning applications require jam jars with lids, specifically lids that create a vacuum. Lids with plastisol liners, such as our lug caps and many of our metal caps, are great for canning because they create an airtight seal.

Boiling jars is a way of sterilizing them, removing any potential bacteria and preparing them for storing food. Empty jam jars are also filled with hot, sterilized jam using the hot fill process.
