As one of the few vineyards to be planted for sparkling and the only vineyard in the state to be planted exclusively for sparkling, Dan and Jeanne will use the extensive knowledge they have acquired over the past five years to experiment with rootstocks, clones and rows. guidance as they work to find the best ways to farm to sparkle in the valley.

Dan and Jeanne’s path to winemaking began over a decade ago when they immersed themselves in their love of sparkling wine through tastings, visits to their favorite champagne growers-producers, and extensive reading. By spending time in Oregon’s Willamette Valley near Jeanne’s hometown of Beaverton, they realized the potential of Oregon’s geography and climate and saw an opportunity to continue the conversation around bubbles through the exploration of different sites and styles. They currently produce about 1100 cases per year.

“We believe the Willamette Valley is one of the best places on the planet to produce world-class sparkling wine,” says Jeanne Feldkamp of Corollary Wines. “The early years of Corollary were spent exploring, understanding, in broad strokes, the relationships between site selection, agricultural choices, winemaking practices and finished wines. Now, with our very own vineyard, we’re excited to take the next step in our journey: creating an integrated, regenerative farming system that’s all about bubble farming. »

Jessica Cortell, owner of a vineyard management company Vitis Terra wine services, helped them find the site and will guide the management of the vineyard. Since 2017, she has helped Corollary source grapes from many talented growers and farmers who are committed to growing sustainably, whether organic, biodynamic or LIVE certified.

“There’s so much we don’t yet know about farming specifically for sparkling wine,” says Jessica Cortell. “Through thoughtful design, choice of plant material and methodical experimentation, Corollary’s new vineyard will help the entire industry better understand the connections between how we grow and what we produce.”
