Jam is used slowly, so smaller jars are better: a half-pint or 4oz jar is finished before it can spoil. Regular-mouth jars pour jam neatly and cost less, and tempered glass with a two-piece lid is essential for a safe seal. Attractive shapes make jars nice for gifting.

Frequently asked questions
What size jar is best for jam?
Half-pint (8oz) or smaller, so each jar is finished before it can spoil once opened. Larger jars work if you use jam quickly or are canning in volume.
Can I water-bath can jam in these jars?
Yes. Jam is high-acid and safe for water-bath canning in tempered mason jars with new two-piece lids, following a tested recipe and correct headspace.
