About 50% of the grapes are ungrafted Grenache sourced from Olegario Sandoval’s vineyard in the Calafia sub-region of the Valle, planted in the 1960s on sandy loam with a little clay. The other half of the fruit is a field blend of ungrafted and dry-farmed bush vine Grenache and friends sourced from the Pro Vi.Va Vineyard in El Porvenir, planted in 1980 on sandy & silty soils.
