Nectarine Butter

Recipe for nectarine butter from http://www.pickyourown.org/peachbutter.htm
Modifications include no spices, use only two cups sugar, add about 1 cup rosé wine, I used La Ferme Julien with the goat on the label.
I also only filled the crockpot 1/2 full with fruit, and used fruit that was nearly ripe--fragrant, but not soft.
