Ok I am a sort of newbie....I have made 6 different wines from scratch with fresh fruit and 2 kits...I used a Black Raspberry wine kit 6 months ago and went totally by instructions..and actually let it sit a week or 2 longer before bottling.now almost 6 months later I have had 3 bottles blow a cork...2 times the bottles were in a different area...I keep my wine in the cooler part of the basement...63 average in the corner storage....help I don't know what to do.
