new wine drinker looking for something sweet

[Brom]

You will find very few wines similar at all to the wines you have note.

Both the M & the MD are made from Concord grapes which are substantially sweeter than the grapes normally used for table wines.

If you are from an area where they make wine locally (they make wine in 49 states but you may not be close to the wine region) visit local wineries and ask for wines made from native American grapes, vitis labrusca.

Try New York wines such as Bully Hill which have national or near national distribution.

Even those American Rieslings called dry Riesling are generally not dry, but they will be dissimilar to Manischewitz or Mogen David.

Another dissimilar wine, but easy to find and inexpensive would be white zinfandels. Most are sweet but ask your merchant for one that is sweet anyway.
