Family History

Since planting the first wine grapes in the Horse Heaven Hills back in 1972, the Mercer family has prided itself on growing a solid base of the Cabernet Sauvignon varietal. Over the years, we have learned that our rich soil and desert climate are beautifully suited for producing elegant tannin structures and enticing flavor profiles. The ability to grow exceptional wine grapes eventually led to the first vintage from Mercer Estates Winery located in Prosser WA in 2005. Today, we still produce mouth-watering Cabernet Sauvignons as well as world class red blends and single varietal wines.

Our vineyards lie on some of the most rugged farm land in Washington with pockets of varied sandy soil types and canyons with differing climactic characteristics. Our vineyards also benefit from the “river effect” providing constant wind pressure which amplifies vine and berry activity.


Our state-of-the-art winery allows our winemaking team the luxury of temperature control and immaculate conditions for fermentation.  The large Prosser facility provides space and efficiencies for true craftsman-style winemaking.  And our barrel rooms allow for long and varied barrel aging programs.  It is with full artistic control that our winemaker blends and creates the new world wines that we at Mercer are so proud to share.

Our Promise

Through instinctual farming, sustainability practices and artful winemaking that Mercer continues to produce award winning wines year after year.

Enjoy Mercer Wines knowing we take the utmost pride in the process from grape to glass.
Each grape harvested specifically for its best fruit flavor. Each barrel blended for taste, mouthfeel and balance.

And each bottle presented for the sole enjoyment
of you – the drinker.
