Harvest Party at Mercer Wine Estates

A Celebration of Wine, Harvest & the Horse Heaven Hills

Fall in Horse Heaven Hills is one of our favorite times of year—the vineyards are in harvest, the production team is working hard right through the glass of our tasting room, and we get to release some of our most exciting wines!

Join us at the Mercer Tasting Room in Prosser to celebrate our 2026 Fall Release and taste the newest wines from our family’s estate vineyards. We’ll have the new release wines flowing, freshly harvested carrots from Mercer Ranches to take home with you, chile, cornbread, and elotes along with live music from Sammy Steele throughout the evening.

Come raise a glass and celebrate the 2026 harvest with us!

Wine Club Members: Two complimentary tickets
Additional Guest Tickets: $30 per person

We can’t wait to welcome you!

Farming for the Next Thousand Years.
