Baja California wine industry Baja seems to be better suited to the production of more and better wines. About 90% of all Mexican wines are produced here and just about all the award-winning vintages do. Most of the wine grapes grown her are those grown in California, with the addition of tempranillo and Chenin Blanc, which is one of the most popular varieties. The dry and hotter climate along with tradition should dictate what is grown here but that is not really the case. Although grape varieties from warmer regions such as southern France, Spain, Italy, etc. are more favored, but about all varietals
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
