Abbot’s Passage Winery & Mercantile

Small lots under Katie Bundschu

Small lots set the pace for Katie Bundschu, winemaker at Abbot’s Passage Winery & Mercantile in Glen Ellen, where she works in Sonoma Valley with Rhone varietals, crisp whites, chilled reds, and the patience that small scale allows. Since 2015, Bundschu has been founder and winemaker here, holding Abbot’s Passage alongside her role leading marketing for Gundlach Bundschu Winery. The two positions ask for different muscles, but they meet at the same point: how a wine carries its authorship, and how a place teaches a guest to read it.

Bundschu’s lineage matters here because she names it plainly. She has spoken of carrying the torch for women in her family who shaped the legacy before they had the same opportunity to stand in front of it. At Abbot’s Passage, she has also said her goal is to bring a female perspective not only to the wines she produces, but to the experiences hosted on site. That is not a decorative claim. It places the wine program, the room, and the label under the same discipline of authorship.

Field-driven blends from overlooked vines

The work at Abbot’s Passage turns on field-driven blending and co-fermentation, with Bundschu drawing from overlooked vineyards and working in small lots rather than folding everything into a larger house style. The stated focus is Rhone varietals, with Zinfandel, Petite Sirah, and Viognier named among the grapes associated with the place. The wines move across still red, still white, rosé, and sparkling, but the through line is not breadth for its own sake. It is the decision to let each lot keep its edges.

The setting gives that method a visible anchor: 80-year-old Zinfandel vines, olive groves, and a historic tasting room in Sonoma Valley. The winery describes its philosophy as sustainable, and the sourcing language includes sustainable and organic. In that frame, the bench is less a fixed station than a sequence of choices, picked fruit, fermenting lots, blending trials, and the final cut.

The tasting room among the vines

The room at Abbot’s Passage stays close to the vineyard rather than separating hospitality from the work outside. Olive trees, old Zinfandel rows, shuffleboard courts, and a historic tasting room shape the pace; the atmosphere is quiet, relaxed, and communal without turning the winery into a stage set. The mercantile element gives the place a softer edge, but the center remains the wine and the hand behind it.

Library and reserve tastings belong to the experience here, which suits a producer built around small lots and field decisions. A bottle can be read beside the vines that frame the property, with the conversation moving from varietal to blend to the way Bundschu wants the guest to encounter the work. If there is a next movement to hold onto, it is the continued tightening of that authorship at Abbot’s Passage: Katie Bundschu, the 80-year-old Zinfandel vines, and the small lots that carry her name.
