Remove the grapes from the vine in whole clusters using a scissors.
Juice the Grapes
Put the grapes in a large pot and mash them.
Add the water so the grapes are nearly covered. If your grapes are larger than Vitis riparia, or you're using a steam juicer you may not need much water, if any. Bring the pot to a simmer cook on low heat for 30 minutes.
Strain the grape juice while still warm through cheesecloth, squeezing out the excess. Save scrap for making wild grape vinegar.
Make the Jelly
Put small metal pie plate or other thin surface over a bowl of ice for a set test.
Mix the pectin and sugar. Whisk the grape juice and sugar mixture, add the butter, bring to a rolling boil on high heat and until it starts to hover around 220F, skimming off any foam. Do not turn the heat down while cooking. If the jelly threatens to overflow your pot is too small.
Set Tests
Here’s where the intuition comes in. Right after the jelly passes 220F, spoon a ½ teaspoon of jelly into the chilled metal bowl to test the set, if it holds it’s shape around the edge and doesn't run like water anymore it’s ready, if not, continue cooking a bit. Drips off of the spoon should hesitate to fall, which is known as sheeting.
I'm usually confident in the set around 223-225F, although if the grapes are cooked with their seeds to make juice (which add natural pectin) it can set around 220F. When the jelly holds it's shape dropped on a chilled plate, turn off the heat and beat in the lemon juice.
Storing
Pour the jelly into sterilized pint or half pint jars screw on the lids. Process the jars in a water bath canner for 10 minutes. Sometimes I don't waterbath can them as they're high in acid and very safe.

Notes
Jelly Didn't Set Pour the jelly back into the pot, add an additional ½ cup water and 2 additional teaspoons of powdered pectin mixed with ½ cup water. Bring it back to a rolling boil, do set tests again and repeat the process. Pectin I use Cuisine Tech brand, which is a full-strength pectin used by chefs, but your favorite, full-strength powdered fruit pectin should work. However, you'll probably need to use 6-8 teaspoons for the recipe. I don’t use pectin that contain sugar or dextrose which has a flavor I don't like and I don't use liquid pectin like Sure-Jell or Pomona's. Tartaric AcidIf you have time, allow the juice to settle overnight and pour it into a fresh jar, leaving any tartaric acid on the bottom. This is optional.
