In 1974, the US winemaker David Adelsheim from the US state of Oregon, on a study trip to France, made the astonishing experience that the local Pinot Noir and Chardonnay vines obviously produced very different or better results (wines) than those in the USA and that they were also much less prone to disease. Three years later, such vines were exported to Oregon and the testing of the vines known as "Dijon clones" began on a larger scale. This was a lengthy process, but today, for example, almost 1,000 hectares of vineyards in Oregon are planted with Chardonnay vines from Dijon. This was followed by Australia, where they were named "Bernard clones" after the scientist, and California. This was the beginning of their triumphal procession, and Dijon vines are now in use all over the world.
