Hi Amy
If you're just getting into wine drinking and want a easy to like sweet wine to enjoy with dinner look out for Moscato.
It is a sweet fruity white wine made from the muscat grape that even tastes a bit like the grape.
You can chill it right down so it should help the transition from beer.
If you're in the US you should be able to find California's Barefoot brand Moscato in a store near you, or just look for the name Moscato.Outside the US look for Moscato in the Italian section of your supermarket.
Just remember that whereas one can gulp beer, wine should be sipped, so it a good idea to have a glass of water alongside your wine glass to use to quench your thirst.
