Tempranillo takes on the flavor of the barrel. Varietal examples of Tempranillo usually exhibit flavors of plum and strawberries. Tempranillo is an early ripening variety that tends to thrive in chalky vineyard soils such as those of the Ribera del Duero region of Spain. In Portugal, where the grape is known as Tinto Roriz and Aragonez, it is blended with others to produce Port wine. For some time, Tempranillo was thought to be related to the Pinot noir grape. According to legend, Cistercian monks left Pinot noir cuttings at monasteries along their pilgrimage to Santiago de Compostela. However, ampelographic studies have
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
