The Castello di Buttrio vineyard is situated on the hillside slopes at 142 metres above sea level, which ensures excellent air circulation to keep the vines healthy. The Guyot-trained Pinot Grigio vines require careful cultivation and are planted in terraces to improve vineyard management. The soils comprise layers of marl and sandstone of Eocene origin, known locally as in Friulian, which contains marine fossils from the Adriatic Sea. This soil produces textured and concentrated wines, balanced by cutting acidity, thanks to the soil's high pH and cool temperature. The vines are cultivated using pest-integrated agricultural methods, with low environmental impact to protect the land, encourage biodiversity and allow the grapes to express the terroir. The ideal diurnal temperature range at harvest time enables the grapes to reach optimal ripeness, with a lovely balance between sugar, acidity and aromatic ripeness - at which point the fruit is carefully harvested by hand.
