I love a semi-sweet riesling. 2007 JJ Prum's Riesling Kabinett is my current favorite.
For local wines, I really like Michigan's Black Star winery. Their late harvest riesling and their chardonnay are excellent. Michigan's Chateau Fontaine also has a nice chardonnay.
On a personal note, by back yard is a few acres big, but narrow & deep, so not really usable..but it is full south-facing...perfect for grape growing...so I often dream of filling it full of grapevines
