There's a cranberry farmer near me in South Haven, Michigan that has also specialized in blueberries for years. (They may be on the Net. Google "DeGrandchamp's Blueberries").
I bought some, threw them into the food processor to break them down, and then put them in a bucket with an equal amount of sugar. Five pounds of berries, five pounds of sugar.
Let them sit for a week or so, and the sugar will start to draw the juice out of the berries. Stir daily, and the seeds and skins will settle to the bottom.
Add more sugar as needed, and pitch the yeast. I made some mighty tasty wine out of them!
