The Ohio River Valley is one of the largest AVAs in America, as it spans parts of four states. In Ohio, this AVA cuts across the southwestern reaches; Cincinnati is in the boundaries. Named for the Ohio River, the vineyards are generally close to the river, to take advantage of the moderating effects. There is a large mix of varieties, from hybrids such as Marquette and Chambourcin to international varieties such as Cabernet Sauvignon, Merlot, Riesling and Chardonnay. While these wines are not as rich or as complex as examples from California (one wouldn't expect them to be, given the climate), there has been some favorable press regarding the top examples of Cabernet Sauvignon and Cabernet Franc, while Ice Wine is starting to become a factor.
