Calcarius are based in Apricena, in the northern region of Gargano, Puglia. The vineyards are characterised by kimmeridgian calcareous soils (thus Calcarius) and are true wines of terroir – mineral, tense, and uncompromising. Valentina has been the leading exponent of biodynamics in Puglia since 2000. The grape varieties are Nero di Troia, Greco Bianco, Bombino, Negroamaro and Aleatico – largely indigenous to the local area and not widely planted outside of it.
