Wash the grapes and remove all stems. Place into a large pot.
Add the honey and lemon juice and mix over medium heat.
Using an immersion blender, blend the mixture until there are no large lumps left.
Bring to a boil. Once the mixture reaches 220F, reduce to the lowest simmer.
Simmer for 25 to 35 minutes or until thickened. Remove from heat.
Once the jelly is cool enough, pour it into mason jars.
Allow it to cool completely and then store in the fridge or freeze.
