Combine wine, pectin and lemon juice in a LARGE saucepot over medium high heat. This bubbles up TREMENDOUSLY and if the pot is too small it can easily overflow.
Bring to a boil, stirring frequently until pectin dissolves.
Once boiling, add all the sugar at once stirring continually until sugar is completely dissolved.
Return to a rolling boil.
Boil vigorously for exactly 1 minute, stirring constantly. Do not be tempted to boil any longer than a minute as the pectin can break down and prevent your jelly from setting.
Remove from heat and skim off any foam.
Ladle hot wine jelly into sterilized jars*, leaving 1/2-inch space at the top.
Wipe jar rims with a clean, damp cloth to remove any residue.
Place lids on jars and screw rings on until snug.
Refrigerate 4 hours until set and use within one month or process in a boiling water bath for longer storage**.
