Abbot’s Passage, a project from sixth-generation vintner Katie Bundschu, is a collection of small-lot field blends sourced from storied vineyards within Sonoma and beyond. We are thrilled to announce plans for expansion this summer into a new historic property in Sonoma Valley. Stay tuned.


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 and beyond to discover its most distinctive vineyard sites from which to make inimitable, character-rich field blends.


Our collection includes distinctive field blends from singular vineyards, each highlighting a unique dirt and climate story. Each wine bears a unique name reflective of its style, origins and provenance. Visit our historic red barn just off the Sonoma Square to experience our wine tasting salon, shop unique retail items or partake in a maker workshop.


Sixth generation vintner, Katie Bundschu (and her canine side-kick Bacchus), has always chartered her own path in life. After college, she pursued a decade-long career in higher education before returning to the family business in 2012. Given her adventurous spirit and driving quest for discovery, Katie was keen to start a new project that branched out from the family vineyard and showcased her family’s longstanding knowledge of unique vineyard sites. Such was born Abbot’s Passage in 2016, with the vision to highlight notable but often-overlooked vineyards across Sonoma and beyond.
