🍇🫙 Concord Grape Jelly 🍞✨

Prep Time: 20 minutes
Cook Time: 15 minutes
Inactive / Drip Time: 4 hours (or overnight)
Water Bath Processing Time: 10 minutes
Total Time: ~4 hours 45 minutes
Yield: About 6 to 8 half-pint (250 ml) jars
Flavor Intensity: Bold, sweet-tart fruit profile
Skill Level: Intermediate (involves fruit extraction and water-bath canning)

Fresh Concord Grapes: 3.5 to 4 pounds (fully ripe, stems removed)
Water: 1/2 cup (for initial fruit simmering)
Powdered Fruit Pectin: 1 package (1.75 oz / 49 g)
Granulated Sugar: 5 to 7 cups (depending on your specific pectin brand directions; traditional recipes generally use an equal ratio to extracted juice)
Butter or Margarine: 1/2 teaspoon (optional, added during boiling to reduce foaming)

Wash and Stem: Thoroughly rinse the Concord grapes, discarding any bruised fruit or stems.
Simmer: Transfer the cleaned grapes to a large, heavy-bottomed stockpot and add the 1/2 cup of water. Crush the grapes slightly with a potato masher to release their juices.
Boil and Soften: Bring the mixture to a boil over medium-high heat, then reduce the heat to low, cover, and let simmer for 10 minutes, stirring occasionally until the grapes are completely soft and liberated from their skins.
Drip Strain: Pour the cooked fruit mixture into a jelly bag or a large strainer lined with several layers of damp cheesecloth set over a deep bowl. Allow the juice to drip completely undisturbed for at least 2 hours (or overnight for maximum extraction). Do not squeeze the bag, as this forces pulp through and results in cloudy jelly.
Crystal Prevention (Optional Tip): For an ultra-clear jelly free of natural tartaric acid crystals, let the strained juice sit in the refrigerator overnight, then decant or strain it one final time to leave any sediment behind.

Prepare Canner and Jars: Sterilize your half-pint mason jars and wash your lids according to standard canning protocols. Keep jars hot until ready to fill.
Measure Juice: Measure exactly 4 cups of prepared Concord grape juice into a large, deep stainless steel saucepan.
Incorporate Pectin: Sprinkle the powdered fruit pectin evenly over the grape juice and whisk vigorously until fully dissolved. Stir in the 1/2 teaspoon of butter if desired to minimize foaming.
Bring to a Boil: Place the saucepan over high heat and bring the mixture to a full rolling boil that cannot be stirred down, stirring constantly.
Add Sugar: Add the measured granulated sugar all at once. Stir well and return the mixture to a full rolling boil. Boil hard for exactly 1 minute, continuing to stir constantly.
Skim and Bottle: Remove the pot from the heat source. Quickly skim off any remaining foam from the surface with a metal spoon. Immediately ladle the hot jelly into your hot, sterilized jars, leaving 1/4-inch (0.5 cm) of headspace. Wipe the rims clean, center the lids, and screw on the bands to fingertip-tight.

Water Bath Process: Place the filled jars into a boiling water canner, ensuring they are covered by at least 1 to 2 inches of water. Bring to a rolling boil and process for 10 minutes (adjusting time upward if you are at a higher elevation).
Cooling: Turn off the heat, remove the canner lid, and let the jars rest in the water for 5 minutes. Transfer the jars upright onto a protected counter space, leaving them completely undisturbed for 24 hours.
Inspect and Store: Check the seals (lids should curve downward and not flex when pressed). Store your sealed jars of Concord Grape Jelly in a cool, dark pantry for up to 12 to 18 months.
