looking for certain types of wine.

[mhix]

I enjoy wine, but prefer the sweeter red wines and medium to light white whites (a touch sweet as well)
my biggest problem is going to a store and finding 1000 different types without really knowing if it is stong, heavy, sweet etc..
It seems that the artfull, fancy prose on the labels is not always helpfull.
What types of wine are generally on the sweet side?
thanks
