Gamay from Pinot noir, another Burgundian grape. It was introduced by Amity Vineyards in 1988. In 1991, Rebecca's Vineyard planted Gamay and was one few Oregon vineyards selling the grapes. LaBete winery was the first to make a vineyard designate of Gamay from Rebecca's Vineyard. Since then, Rebecca's Vineyard stopped selling Gamay to those who would only blend into their Pinot Noir for flavor and color enhancement, and to only sell to those who would produce stand alone Gamay. Younger wineries like Division Winemaking Co., who are now the largest producer of Gamay in Oregon, have helped raise awareness and availability
Petite mutation petite negative mutants. Potentially, these yeasts have a different inheritance system in place for their mitchondrial genome than "S. cerevisiae" does. The frequency at which "S. castellii" spontaneously produces petites is similar to that of "S. cerevisiae", with the mitochondrial DNA of those petites being highly altered via deletion and rearrangement. Suppressive petites of "S. cerevisiae" are the most commonly observed spontaneously created mutants, whereas in "S. castellii," the most commonly observed spontaneous mutant is the neutral petite, further leading to speculation that the transference of this mutation differs between species. Petite mutation petite (ρ–) is a mutant first discovered
