The Cortese grapes are selected from vineyards of clay marl soil rich in iron located on high hills near the town of Gavi. The sea breezes from the Ligurian Sea and cool mountain winds from the Apennine Mountains create a microclimate ideal for growing Cortese grapes to optimal ripeness. The grapes are pressed without crushing and the must is cold settled before undergoing a low-temperature fermentation using indigenous yeasts. The wine is aged for 3 to 4 months on the lees in stainless steel tanks before bottling.
