Founded by husband-and-wife duo John House and Ksenija Kostic in 2011, Ovum is a celebration of the diverse expressions of Oregon Riesling. After years of learning the intricacies of the Willamette Valley while working together at Chehalem, John and Ksenija set off to further investigate the myriad terroirs of Oregon through the lens of Riesling, and now source fruit from through the state. They have found sites with blustery Pacific winds, extreme diurnal shifts, and rocky, well-draining soils.

To emphasize the idiosyncrasies of these vineyards, all of Ovum's wines see the same practices in the cellar: natural fermentations, no additions or subtractions except for SO2, extended lees contact of 8-9 months – all in neutral barrels of acacia and oak, as well as Nomblot concrete eggs. The resulting wines are textured and concentrated, driven by minerality, and framed by unwavering acidity. Ovum's work is among the most compelling white winemaking we have encountered in our search throughout the Pacific Northwest.

Wine & Spirits 94 "Here is a gewurztraminer that feels like a pinnacle for the variety: complex, full of grain and spice and floral scents. And yet it’s so ample, so generous, you’ll almost miss its complexity—the sunny litchi, apple and orange peel fruit character. The sensuous texture is a

Wine Enthusiast 94 Cellar Selection "This wine's initial baby powder scents give way to a bone dry palate of astonishing intensity. Fermented with native yeast in neutral wood, it has almost feral complexity. Lemon and citrus flavors abound, with grapefruit and orange liqueur accents. The length

John Gilman 93 "The bouquet wafts from the glass in lovely and utterly classic blend of lychee nut, rosewater, a touch of spices meats, a nice dollop of soil and a touch of white flowers in the upper register. On the palate the wine is deep, full-bodied, crisp and nascently complex, with an
