The vineyards are situated above the dense layer of fog that creeps up the Napa Valley most evenings. Consequently the vines warm up earlier in the morning and stay warm through the night. The combination of warm temperatures, steep hillside vine rows and gravelly soils promotes more stress on the vines leading to increased intensity in the finished wine. Situated on steeply terraced rows directly beneath the winery, the three-acre block produces exceptionally rich, deeply flavored fruit. Composed of 95% Merlot from the estate Mailbox Vineyard and 5% Cabernet Franc from the estate Upper Bowl Vineyard.
Eleven acres of Merlot vines have been planted in the rocky soils surrounding the winery, and it is these vines that produce some of the finest Merlot in Napa.
