Gamay the more "elegant" Pinot Noir. Sixty years later Philippe the Good issued another edict against Gamay in which he stated the reasoning for the ban is that ""The Dukes of Burgundy are known as the lords of the best wines in Christendom. We will maintain our reputation"". Gamay is a very vigorous vine which tends not to root very deeply on alkaline soils resulting in pronounced hydrological stress on the vines over the growing season with a correspondingly high level of acidity in the grapes. The acidity is softened through carbonic maceration, a process that also allows the vibrant youthful
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
