The grapes for Prima are sourced from vines aged 25 years from the villages of San Roman de Hornija, Villaster and Morales. The vineyards for this wine are growing in sandy-clay soils as opposed to the stonier soils of fruit sourced for San Roman and are trained both en vaso and to wire. The winter of 2007-8 was mild and quite dry. Rains through April and May supported growth through the season. Veraison took place in mid-August, about 10 days later than 2007. Weather during the growing season was mild and dry leading to healthy grapes. Harvest was started on September 19th during a period of hot days and cool nights. The slow maturation and temperature shifts of this season lead to a wine that shows deep colors and a marked minerality.
The grapes are harvested by hand with a selection of grapes in the vineyard. The wine is fermented in temperature controlled, conical, stainless steel tanks which allow for caps to naturally be broken very softly during pump overs. The wine was aged for 12 months in second and third fill French and American oak barrels, which had previously been used for the maturation of San Roman. Unfiltered.
