Tempranillo more acidic wine. Tempranillo is the major component of the typical Rioja blends and constitutes 90-100% of Ribera del Duero wines. In Australia, Tempranillo is blended with Grenache and Shiraz, also known as Syrah. In Portugal, where it is known as "Tinta Roriz", it is a major grape in the production of some Port wines. Tempranillo is native to northern Spain and widely cultivated as far south as La Mancha. The two major regions that grow Tempranillo are Rioja, in north central Spain, and Ribera del Duero, which lies a little farther to the south. Substantial quantities are also grown
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
