Terra Valentine was founded in 1996 by Angus and Margaret Wurtele when they purchased a newly producing vineyard on Spring Mountain and named it the Wurtele Vineyard. In 1999, they hired Sam Baxter and his father Phil, and began making wines at the historic Yverdon Winery on Spring Mountain. The doors of the winery opened to the public in 2002. In 2014, after 15 years of successfully developing a world-class wine business, Sam and Angela Baxter purchased the company from the Wurteles to continue the legacy of Terra Valentine wines. The Wurteles continue to farm the Wurtele Vineyard located at 1,000 feet on Spring Mountain and the Yverdon Winery was sold to Jackson Family Wines in 2013.
