Arroyo produces wines from Ribera del Duero, the prestigious wine region of Castilla y León in Spain. The winery focuses on Tinta del País and Tempranillo, the native and classic grapes of the region, known for their structure and depth in this continental climate. Señorío de Sotillo Reserva, made from Tinta del País, represents the winery's top expression and has been rated by Wine Enthusiast and Wine Spectator. The portfolio also includes San Jorge de Sotillo Reserva Tinto, a Tinta del País wine, and San Jorge de Sotillo Roble, a younger Tempranillo expression that shows the versatility of the estate's fruit across different aging regimens. Ribera del Duero's high altitude and diurnal temperature swings produce wines of notable concentration and acidity, characteristics evident in Arroyo's range.
