Unculín is a Vino de Villa wine from over 80 different organically-grown, family-owned small plots in the village of Valtuille de Abajo. At 500m to 650m elevation, they are planted with 60 to 100-year-old traditional bush vines from native varieties, including mencía, alicante bouchet, merenzao, palomino, and doña blanca from various parts of Valtuille that are known for producing fresh, elegant wines, including: Cabanelas (clay soils), Mata los Pardos (sand and clay), and El Val (pebble soils), among others. Crucial to the quality and complexity of JAG’s wines is the genetic heritage of their ancient vines, planted mostly before the industrialization of Spanish wine. With some vines in Valtuille being between 100 and 200 years old, their vineyards provide an unspoiled genetic window to an era before modern clones were selected for higher yields. The viticulture is strictly organic, and the only compost used is local, organic chestnuts, which grow in the vineyards.
