Ohio River Valley Ohio River Valley AVA is the second-largest AVA covering over 16 million acres
(well over 6 million hectares) along the Ohio River in the states of Indiana, West Virginia, Kentucky and Ohio.
To its south is a humid subtropical climate; to the north a humid continental climate providing
for an interesting mix. While most of the vineyards are planted in hybrids
Chardonnay, Cabernet Sauvignon, Cabernet Franc, and Riesling also grow here.
Many critics say that the region is simply too large to be useful as an indication
of wine typicity.
