Wow!! Thanks for the detailed information, Brian!!!
Reading your post made me dig out my October, 2004, Wine & Spirits magazine article from Rod Smith, entitled “Raiders of the Lost Zin: Purple Treasures from Russian River’s Centennial Vineyards”.
The author interviews Greg LaFollette, then-winemaker at DeLoach, Mike Officer of Carlisle, and Hartford’s Mike Sullivan. Peter Fanucchi, Mike Feeney (the late Tom Feeney’s nephew), and Lloyd Chelli all contribute their stories in this 4-5 page survey of the vineyards that (at the time) had survived the pressure to replant to Pinot Noir and Chardonnay.
The VIE Winery website does a pretty good job of concisely explaining the arrangement of the “Tom Feeney Vineyard” complex, even if its data also is no longer 100% correct:
“…The ranch consists of five distinct vineyards within a 1 mile radius of each other in the Laguna de Santa Rosa flood plain in Russian River Valley. Tom Feeney’s ‘home block’, what is known as the ‘Piner Vineyard’, was planted in the mid-1940s with cuttings from his neighbor, Bernardo Montafi. Tom later bought his neighbor’s vineyard, commonly know as the ‘Montafi Vineyard’, along with a vineyard on River Road, and two vineyards made famous by DeLoach in the 1980s-90s called the ‘Barbieri’ and ‘Papera’ Vineyards.”
To the extent of my knowledge, the “Barbieri Vineyard” is no more and no winery, save Hook & Ladder, gets fruit from the "Gambogi Vineyard".
The Grape-Nutz archive pages include a considerable amount of TN’s & “Bloody Pulpits” discussing the RRV’s old-vine Zinfandel sites from producers like DeLoach, who produced single-vineyard bottlings from “Gambogi”, “Papera”, “Saitone”, etc.
