Concord Grape Jam

Concord Grape Jam is a low-sugar or low-honey cooked jam made with Pomona’s Pectin. Pomona’s Pectin contains no sugar or preservatives and jells reliably with low amounts of any sweetener. See below for where to buy.

Yield: 4 to 5 cups

Before You Begin:
Prepare calcium water. To do this, combine ½ teaspoon calcium powder (in the small packet in your box of Pomona’s pectin) with ½ cup water in a small, clear jar with a lid. Shake well. Extra calcium water should be stored in the refrigerator for future use.

Concord Grape Jam Ingredients

3 lbs Concord grapes (to make 4 cups prepared grapes)
2 teaspoons calcium water
½ cup up to 1 cup honey or ¾ cup up to 2 cups sugar
2 teaspoons Pomona’s Pectin powder

Concord Grape Jam Directions

1. Wash jars, lids, and bands. Place jars in canner, fill canner 2/3 full with water, bring to a boil. Turn off heat, cover, and keep jars in hot canner water until ready to use. Place lids in water in a small sauce pan; cover and heat to a low boil. Turn off heat and keep lids in hot water until ready to use.

2. Pop the skins off the grapes and set the skins aside. To separate the pulp and juice from the seeds, either put the skinless grapes through a Foley Mill or cook the skinless grapes with a little water, mash them up, and put through a Foley Mill or strainer. Collect all the juice and pulp and discard the seeds.

3. Puree the skins in a food processor or blender. Add the pureed skins to the juice and pulp and mix together well.

4. Measure 4 cups prepared grapes into sauce pan.

3. Add calcium water and mix well.

4. Measure sugar or room temperature honey into a bowl. Thoroughly mix pectin powder into sweetener. Set aside.

5. Bring fruit mixture to a full boil. Add pectin-sweetener mixture, stirring vigorously for 1 to 2 minutes to dissolve the pectin while the jam comes back up to a boil. Once the jam returns to a full boil, remove it from the heat.

6. Fill hot jars to ¼” of top. Wipe rims clean. Screw on 2-piece lids. Put filled jars in boiling water to cover. Boil 10 minutes (add 1 minute more for every 1,000 ft. above sea level). Remove from water. Let jars cool. Check seals; lids should be sucked down. Eat within 1 year. Lasts 3 weeks once opened.

  1. My first ever batch of Concord grape jam was made with your pectin. I ran the grapes twice through my Victorio strainer and got 16 cups of thick juice from about 11 lbs of grapes – homegrown. Used a cup of sugar and the taste is a little tart but very fruity. The second batch had three cups grape and a cup of pomegranate juice, a cup of honey and 1/2 cup of sugar, added just before removing from the heat because it was too tart. Great flavor and texture.

    • Hello Jeff,
      Glad your jam came out to your liking! That was smart on your part to wait until after the pectin was dissolved to taste and add more sweetener. As you probably know, Pomona’s Pectin only dissolves and jells properly in a low-sweetener environment; and 1 cup of honey is the top end of the sweetener range for 4 cups of mashed fruit or juice to be jelled. But you can always add a bit more sugar just before removing from the heat, as you did.

      Thanks for using Pomona’s Pectin — and happy jamming!

  2. I made this using seedless Concord grapes that I put through my food mill. It was super easy with the food mill. I didn’t bother with the blender. I just rinsed the grapes and stemmed them and put them straight into the food mill. Not all of the skins passed through, but most did. I got 4 cups of crushed/ground grapes, including the juice, pulp and skins from 3 lbs grapes.

    I used 1 1/4 cups organic sugar, which resulted in a wonderful, just slightly tart jam. My daughter loves it so much she just eats it out of the jar! Thank you for sharing this recipe.
