Can you recommend a good sweet tasting white wine that can be purchased at...

[Daddy's Girl]

...grocery or liquor store? smooth, sparkling or non sparkling
organic is ok too

Verdello and Moscato are both really nice sweeter wines, I tend to find reisling to be too dry.
Hope you find something

Reislings are normally pretty sweet. They can also be bought in nearly any price range so it won't break the bank to try a few until you find one you like.

Reisling is a great sweet white wine. White Zin is good too.
