The Viura and Tempranillo Blanco grapes are harvested from a single plot, slightly sloping, in a high altitude area of Haro. The soil is stony alluvial - with pebbles on the surface and limestone below. The vines are low yielding, and harvesting is by hand into 200kg crates. The grapes are hand-sorted at the winery then lightly pressed (around half the stems are included) and spontaneous fermentation occurs. Alcoholic fermentation is in stainless steel at 16ºC, then half the wine spends 5 months in French oak (not roasted, steam bending) with its lees, and half is aged with lees in concrete. The parts are then blended and bottled.
