Canning Berries: Raspberries, Blackberries & Blueberries

QUANTITY: An average of 12 pounds is needed per canner load of 7 quarts; an average of 8
pounds is needed per canner load of 9 pints. A 24-quart crate weighs 36 pounds and yields 18 to 24 quarts – an average of 1-3/4 pounds per quart.

PREPARING BERRIES:

  1. Wash 1 or 2 quarts of berries at a time.
  2. Drain, cap, and stem if necessary.

  1. Fill jars with any of the raw berries, shaking down gently while filling.
  2. Cover with hot syrup, juice, or water, leaving 1⁄2-inch headspace.
  3. Adjust lids and process in boiling water bath. 
A table shows canning times for raw pack by jar size and altitude. For pints: 15 min (0-1,000 ft), 20 min (1,001-6,000 ft), 25 min (>6,000 ft). For quarts: 20, 25, 30, and 35 min respectively.

Expert Tips

  • Start with the Best Berries: Choose berries at their peak ripeness. Remove any overripe or damaged fruit immediately, and use within 24 hours of picking or buying for optimal freshness.
  • Rinsing Berries: Don’t wash blueberries before freezing, but otherwise wash berries carefully in cool water. Don’t leave them to soak – they’ll get waterlogged.
  • Preserving Efficiently: Keep berries refrigerated between washing and preserving, and work in small batches if needed. I like having all the equipment ready before starting, and I just do one type of preserving at a time.
