Forty years after its official inception, the Ribera del Duero DO is experiencing a period of change, with a wide range of new wines and styles that run the gamut from traditional to strikingly forward-thinking. Whether its producers are focused on expressing the identity of a region or looking to push the boundaries of what can be done with premium red wines in the higher areas of Castilla y León, the DO offers a diverse range of reds along with a handful of whites whose character is defining the area’s transition from the past into the present.
