Abbot’s Passage, a new project from the Bundschu family’s sixth generation, is a highly-allocated collection of unique field blends sourced from storied vineyard sites within Sonoma.


The name pays homage to an abbot from Mount La Salle Christian Brothers who, according to local legend, trekked weekly from Napa into Sonoma along an ancient native american footpath – a wild, heavily wooded ridgeline passing through the current Bartholomew Park Vineyard – to reach his favorite watering hole.


Leveraging 30 years of single-vineyard sourcing, this concept represents our family’s pioneering pursuit of discovery – our quest to survey the peaks and valleys of Sonoma to discover its most distinctive vineyard sites from which to make inimitable, character-rich field blends.

Our inaugural wine, 2013 Due West, is a single-vineyard Cabernet Sauvignon hailing from Nuns Canyon – a steep hillside vineyard perched atop Moon Mountain AVA, farmed organically by Phil Coturri and expertly crafted by winemaker Anne Dempsey. The two blocks of Cabernet Sauvignon were co-fermented, giving this wine depth and complexity honoring its idiosyncratic mountainside origins.

Blocks 4 and 21 of this steep and exposed hillside vineyard were hand-picked at the first light of dawn on October 8, and optically sorted at the winery. The blocks were combined in gravity-fed tanks where they were cold-soaked for 3-5 days, co-fermented including a 26-day extended maceration and then the free run drained into barrels to complete fermentation.

The wine was aged 20 months in 18 thin-stave French oak barrels. The 6 favored barrels were racked and blended in Summer 2014. Prior to bottling in June 2015, the 5 best barrels were selected for the final blend which was then aged for 1 year in bottle.
