Twenty- to 30-year-old vines are planted to south-facing vineyards 80 meters above sea level in volcanic soil with white sand and chalk deposits. The fruit is handpicked and the skins are gently broken. Fermentation is in stainless steel tanks and lined vats with regular punching down. A first blending of lots takes place when the wine is placed in barrique; a second at the first racking. The wines are then bottled with minimum intervention.
