Who We Are

A corner of Wahluke Slope that tastes like home

StoneTree Vineyard sits at the intersection of two passions: the slow craft of bread-making and the joy of gathering quality provisions under one roof. We opened our doors in Prosser because this corner of Washington — sandwiched between vineyards and wheat fields — has always felt like a place worth building something real.

Our bakers arrive before dawn. Our shelves are stocked with locally sourced goods, seasonal specialties, and pantry staples that we'd be proud to keep in our own cupboards. Whether you're picking up a sourdough loaf on your way home or browsing our selection for a weekend gathering, we want every visit to feel like a small celebration.

Our Story

Born between the vineyards and the wheat

Prosser isn't the first city people think of when they imagine a bakery — and that's exactly why we chose it. The Wahluke Slope has been feeding the world with wine grapes and grain for over a century. We wanted to add our own chapter to that story.

StoneTree Vineyard started as a weekend stand at the local farmer's market, selling what we could bake from our home kitchen. The response was overwhelming — people didn't just want bread; they wanted to know where it came from, who made it, and what went into it.

Today, we operate from our shop on South Griffin Road, where our ovens fire up before sunrise and our shelves are stocked with goods from a growing network of Washington State producers. We partner with local vineyards, orchards, and farms to bring you flavors that actually reflect this place.
