The leaves of Pinot noir are generally smaller than those of Cabernet Sauvignon or Syrah and the vine is typically less vigorous than either of these varieties. The grape cluster is small and conico-cylindrical, vaguely shaped like a pine cone.
Some viticultural historians believe this shape-similarity may have given rise to the name.[2] In the vineyard Pinot noir is sensitive to wind and frost, cropping levels (it must be low yielding for production of quality wines), soil types and pruning techniques. In the winery it is sensitive to fermentation methods, yeast strains and is highly reflective of its terroir with different regions producing sometimes very different wines. (Wikipedia)
