The Assyrtiko grapes are grown in the in semi-mountainous limestone soils of Koutsi of Nemea. The soils are rich in calcium carbonate with a relatively neutral pH, and like most limestone soils in Greece, they have low organic matter content. The 15-year-old vines are planted at 600 metres altitude with a south-westerly orientation where the Assyrtiko vines flourish in the free-draining soils. The winters are relatively cold and wet, rarely falling below 0°C. Summers are hot but without excessive temperatures; however, a few thunderstorms in June are common. A long autumn follows, and the warm days and cool nights of September, combined with typically dry conditions, form ideal conditions for the maturation of the grapes. The vineyard is carefully pruned strictly to reduce yields and produce fruit with concentrated flavours.
