Tempranillo blanco or uproot a previous planting of another variety. Wineries are able to use Tempranillo blanco in blends or as a varietal bottling. Tempranillo blanco produces medium-sized clusters with loose, average size berries that are yellow-green in color. The variety buds late but goes through veraison and ripens early. At harvest the grapes usually have a high malic acid and high levels of aromatic phenolic compounds such as terpenes that contribute floral, tropical and citrus notes to the wine. As a new variety, growers and winemakers are still learning about Tempranillo blanco and the types of wines it can produce. Winemaker
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
