Our wine is too sweet!

[Louey]

HELP! We are total novices and just messed up our wine!

We decided to make our own wine last fall and we recently tasted it. It is very sweet. We suspect that we let the grape juice get too cold in the early stages ( it actually turned a little slushy before we moved it to another location)and so have ended up with sweet wine. Can any corrective measures be taken or should we throw in the towel?
