The vineyards are located in Zamora, Valdefinjas and Villabuena. Toro is certainly famous for having many ungrafted/original vines here that have not been affected by the grape aphid (Pre-phylloxera). The sandy soils prevented the louse from digging tunnels to reach the area. This in contrast to more than 95% of all vineyards that were lost in that time, so we are still talking about ungrafted and therefore original authentic grapes (vines).
