I spotted this question on the Money Saving Expert forums earlier today:

I bought some ginger wine from sainsburys to try but it is far too sweet. I don’t want to waste it, but I can’t stand to drink it. Any ideas what else I can do with it?

Other forum posters suggested using a splash of it in brandy and hot water to make a winter cocktail, or with ice in lemonade for a summery one. Another suggestion is to use it to make a ginger-y trifle.

Any other ideas?
