Vintage Notes

In 1987, the Oltranti family purchased the Mazzoni Home Ranch vineyard. They began selling grapes from their nineteenth century vines to Ridge in 1996. They planted their fallow terraces to zinfandel in 1998. The quality and complexity improved as the vines matured. We made our first Oltranti bottling in 2004. This excellent vintage produced our third, and a deliciously appealing one. It will be enjoyable now through 2026.


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.
