The Mill Keeper is a California wine brand rooted in Napa Valley’s heritage, created to honor the agricultural pioneers who first planted vines in the region during the mid-1800s. The name pays tribute to the “mill keepers” of that era, hardworking individuals who operated grain mills and played a vital role in sustaining early farming communities. By drawing on this history, the brand positions itself as both a celebration of Napa’s deep-rooted traditions and a modern expression of the valley’s renowned winemaking.

Founded by the PlumpJack Collection of Wineries, The Mill Keeper focuses on producing wines that are approachable, balanced, and crafted for everyday enjoyment, while still reflecting the quality and prestige associated with Napa Valley. Grapes are sourced from a mix of sustainably farmed vineyards, and the winemaking approach emphasizes both consistency and character, making the wines versatile enough to appeal to a wide audience.

The brand’s identity blends heritage and accessibility—its storytelling connects to Napa’s past, while its wines are designed to be enjoyed in the present. With elegant packaging and a philosophy centered on authenticity and respect for the land, The Mill Keeper has quickly become recognized as a label that brings the legacy of Napa to the modern wine drinker.
