Hi Liz,
For a sweet red Port is probably your best choice. However, if you can make a trip to Chataqua County, get your hands on some Johnson Estate Delaware Ice Wine - available only at the winery (it's white).
Sweetening a wine before bottling is a bit tricky. First of all, the wine must be very clear and the SO2 level (from adding the potassium metabisulfite) should be higher than for a dry wine. Unless you have access to a sterile filtration system, you will need to add potassium sorbate to prevent any lingering yeast cells from re-starting fermentation once the sugar is added. Remove about a half gallon of the wine. Pour about a quart of the wine into a mixing bowl. Add the sugar to the bowl and stir until it is all dissolved. 1 cup of sugar in 5 gallons of wine will result in about 1% sugar. This is just above the perceptible sweetness level. About 1.5% is a good target for an off-dry, but that can depend on the acidity of the wine. Add the potassium sorbate and another dose of potassium metabisulfite to the bowl and stir it in. Stir this back into your batch of wine and top up the container with the remaining wine you removed. Then bottle the wine. If you sweeten using cane sugar (sucrose) you should wait about 2 months after bottling before drinking it. The reason for this is that sucrose is a di-saccharide (double sugar ring) and the acid in the wine will break the sucrose into two mono-saccharides (single sugars), fructose and glucose. These taste a bit different than the sucrose and will also give the wine a different mouthfeel. Also, while this transformation is taking place, the wine will exhibit an "off" flavor until it is complete.
