Blueberry and Sparkling Red Moscato Jelly

I love the use of wine in this recipe, it is the first time I have added it to a jam and it gives it such a wonderful unique taste.  From Food and Drink Spring 2016.

4 cups blueberries, fresh or frozen
1 cup sparkling red Moscato wine
6 cups sugar
Juice of 1 large lemon, about 1/3 cup
1 pouch (85ml) liquid pectin

•  Before you start cooking, pop a plate into the freezer; you’ll use that in a little bit to test the readiness of the jam.
• Into a large, heavy-bottom saucepan over medium-high heat, add the blueberries, wine, sugar and lemon juice. Bring up to a good boil, stirring constantly and watching closely, in case it starts to foam and boil over.
• When it comes to a boil, add the whole pouch of liquid pectin—try to squeeze out every drop; you need it!—stir in and bring back up to the boil. Boil for about 1 minute stirring constantly.
• Spoon a drop of hot jam onto that chilled plate and pop it back into the freezer; if it begins to gel or set within 30 seconds or so, it’s time to bottle. If not, boil for another minute, then retest.
• To bottle, transfer the still-hot jam into warm, sterilized jars. Don’t overfill; about ¼ inch (5 mm) from the top is perfect.
• Pop on the lids, tighten, and finish canning by submerging the filled, tightly sealed jars into a very large pot of boiling water for about 20 minutes. Remove from the water bath and allow to cool on the counter. You should hear a chorus of metallic clinks and clunks coming from the kitchen, as the seals set tight!
