Tempranillo sandy areas, as well as for vines that are less than twelve years old, as the roots are generally too superficial. Tempranillo wines are ruby red in colour, while aromas and flavours can include berries, plum, tobacco, vanilla, leather and herb. Often making up as much as 90% of a blend, Tempranillo is less frequently bottled as a single varietal. Being low in both acidity and sugar content, it is most commonly blended with Grenache (known as "Garnacha" in Spain), Carignan (known as "Mazuela" in Spain), Graciano, Merlot and Cabernet Sauvignon. Blending the grape with Carignan makes a brighter and
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
