If you're just looking to soak fruit in alcohol for a few months to get some flavor in the alcohol, this is a good site: http://www.infused-vodka.com/infused...ecipebook.aspx
It's also how people make lemoncello. You'll find a ton of recipes out there; all are good.
If you're looking to start a fruit wine, and then dump in alcohol to kill off the yeast about mid-ferment to keep the residual sugar and boost the alcohol, try looking for a fortified wine recipe, or a port style recipe. Can't think of any off the top of my head, but I made a peach port style wine like this once and it's really good.
