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 mutation petite (ρ–) is a mutant first discovered in the yeast "Saccharomyces cerevisiae". Due to the defect in the respiratory chain, 'petite' yeast are unable to grow on media containing only non-fermentable carbon sources (such as glycerol or ethanol) and form small colonies when grown in the presence of fermentable carbon sources (such as glucose). The petite phenotype can be caused by the absence of, or mutations in, mitochondrial DNA (termed "cytoplasmic Petites"), or by mutations in nuclear-encoded genes involved in oxidative phosphorylation. A neutral petite produces all wild type progeny when crossed with wild type. petite mutations can
