According to the Bible, wine is the fruit of grapevine and human labour, but the reality seems to be more intricate. To make wine and serve it optimally, you need to create the perfect balance between aromas and flavours. It will depend on three essential criteria: grape variety, soil and climate - which in combination gives quality to the wine.
The character of some varieties like Sauvignon, Gamay, Pinot grigio, Dolcetto is revealed early on. What is mostly sought after is their easy fruity and tasty character. Varieties like Cabernet-Sauvignon, Merlot (Bordeaux, California), Sangiovese or Nebiollo (Italy), Syrah and Grenache (South of France and Australia) have pottential for producing great wines for storage.
Ideal soil doesn't exist. Granite fits to Syrah and Gaay, chalky soil suits to Chardonnay and Pinot Menuier as we can see in Champagne. Schist gives spicy red wines and if clay soil reduces the bouquet, it contributes to build the wine.
Hot weather gives a deep rich flavour lacking in acidity or bright fruit. The hotter the region the more flabby (less acidic) the wines tend to be. Cool weather
Long cool growing condition pronounces the fruit and the acidity. Tannins and colour are low. Temperate weather. If it is not too hot nor cold, the ideal grape variety are those with long growing seasons, but thick skins to protect the fruit. Tannin and colour are products of the grape skin.
