カリフォルニアの濃いピノを「シラーみたい」という人はよくいますが,実は本当にシラーとピノは遺伝子的に近かったことが判明しました。
"Grapevine geneticists José Vouillamoz and Stella Grando of the Istituto Agrario, San Michele all'Adige in Italy used a recently-developed technique for assessing probabilities that had never been applied to grape cultivars before to unravel this unexpected kinship. They analysed 89 cultivars which led them to calculate the likely genetic relationships between Pinot, Syrah, Dureza, Teroldego, Lagrein and Marzemino, the first three being associated with eastern France while the second three, all genetically related, are grown south of the Alps in northern Italy."
