Winemaker Tasting Notes

Garnet-ruby color with nose of ripe cherries, raspberries, clove, baked dessert, and sweet toasted oak. Bramble fruit on the palate with smooth-polished tannins, lively acidity, and a long finish. EB (3/20)

Vintage Notes

Winter was dry, leaving the vines short on water. Cool summer weather slowed vine growth, but a return to warmth in September prompted harvest. The grapes were destemmed and crushed into small tanks. Pump-overs during fermentation easily extracted full color and tannin. Once malolactic finished, the wine was racked to barrel. The spice from oak aging complements the wine’s appealing fruit. Enjoyable now, it will continue to drink well over the next five years.


Niccolo and Flora Oltranti purchased the old Mazzoni Home Ranch in 1987. They set about restoring this historic property, working on the buildings (Nic was an engineer) and tending the surviving nineteenth-century vines. (Ridge has made Mazzoni Home Ranch from these old vines since 1996.) Once the old vines recovered, Nic and son Paul turned to the abandoned hillside vineyards above. Replanted to an old zinfandel field selection, these young vines have begun to produce the quality that seems inherent to this exceptional zinfandel site.
