Almost 30 years ago, John Caldwell wrote a legendary book called "A Guide to Grapevine Clones for Professionals." This treasure served as a compass for U.S. winemakers and growers seeking the best clones for making high-quality wine.

Decades later, Clone Book 2.0 is underway, a collaborative effort by John Caldwell (aka JFC) of Caldwell Vineyard and Deborah Passin of VinEthos. Together, they'll deliver a comprehensive review of the latest clones, strategies for resilient vineyards and invaluable insights from wine-industry luminaries.

This blog will share highlights of Deborah's journey through France, Italy, Spain, Portugal and the U.S. as she interacts with researchers, scientists, winemakers, and growers to shape the upcoming book. Join us for this exciting exploration!
