At the upper end of the Chardonnay planting, where the quartz incidence in the soil is the greatest the fruit has extra complexity, finesse and intensity. This wine comes exclusively from this soil. This area is approximately half one hectare in size. The characteristics are similar in the Quartz Chardonnay to the Kostas Rind Chardonnay but all aspects are amplified here yet remain in complete harmony.

The winemaking is the same for both wines however the Quartz Chardonnay sometimes spends a few months longer in barrel and there is a higher percentage of new wood used, being around 35%.

Production varies from 150-250 dozen per vintage.
