Researchers Complete Genome Sequencing Of Uruguay’s Prize Grape Variety

September 2, 2013: 12:00 AM EST
Scientists in Uruguay have sequenced the genome of the country’s Tannat grape, purported to produce the healthiest wines in the world because of their high concentrations of the antioxidant tannin and of the flavonoid procyanidin. The researchers, who say wines made with Tannat grapes have twice the tannins of Cabernet, Merlot or Pinot Noir, believe that sequencing the grape's genome will allow Uruguayan vintners to protect “a valuable niche in the world's $300 billion wine industry”. The scientists will now turn their attention to determining how soil conditions, minerals, sun, temperature, climate, altitude and other environmental factors affect the expression of genes in grapes and the chemistry of wine's aromas and color.
