Our story

In 2005, we purchased 10 acres of established wine grapes in Washington’s Rattlesnake Hills AVA, part of the renowned Yakima Valley. Bosma Estate Vineyards was born.

A decade later, we expanded three miles up the road, carving out 50 more acres framed by native sagebrush and rugged contours. That site became Diamondback Ridge Vineyard: where every vine is grown with winemakers in mind.

Our Rattlesnake Hills AVA site & layout

The Diamondback Ridge vineyard sits at 1,410 feet and features a series of east- and west-facing fingers—natural contours that let us plant varietals where they’ll get the right amount of morning or afternoon sun.

We use both traditional north–south row alignment and a 22° off true North to maximize sunlight exposure and airflow. These site-specific choices create balance and concentration in the fruit.

Our wine grape varietals

We specialize in premium wine grapes for boutique winemakers, with a focus on clonal diversity.

Take our Cabernet Sauvignon blocks—they feature six clones (4, 6, 7, 8, 15, and 33), giving you the freedom to craft distinctive blends or showcase a single clone’s character.
