  • 8 cups concord grapes rinsed
  • 1/4 cup water
  • 6 cups granulated sugar
  • juice of half a lemon
  • 1/2 tsp unsalted butter


  • Remove the grape skins from the grape pulp. You can do this by giving a grape a squeeze between two fingers. Place the pulp in a medium saucepan and the grape skins in a large bowl.
  • Once all the grape skins and pulp have been separated, place the saucepan with the pulp over medium heat. When the pulp comes up to a boil, reduce heat to low and let the pulp simmer until it becomes a liquid. It should take about 10 minutes.
  • Place the skins into a food processor and pulse it until the skins are coarsely chopped.
  • Add the skins in a stock pot with 1/4 cup water. Heat over medium heat until the skins come up to a boil then reduce to low to simmer. Let the skins simmer about 10 minutes.
  • Put the liquified pulp in a sieve or food mill over the stock pot with the skins and push the pulp through. Discard seeds.
  • Stir to combine the pulp and skins. Add in the sugar, lemon juice, and butter. Stir to combine ingredients.
  • Let the mixture come up to a boil over medium heat. Stirring occasionally.
  • Once the jam comes up to a boil, reduce heat to low and simmer until the jam is reduced and thickened. A sure way to tell if the jam is ready is put a plate in the freezer to chill. Once chilled, pull out and dab a spoon full of jam on it. Place back in the freezer for 1 minute. Push the sides of the jam with your finger and if it doesn't move it's ready!
  • Place the hot jam into hot sterilized jars. Wipe the rim with a damp towel. Place a hot lid on and ring. Tighten the ring down. Place into the hot water canner and make sure the water covers the lids. Once the water comes up to a boil, boil for 10 minutes. Remove from water and place under a warm towel. Let it sit overnight.
