Pinot Noir is a world-conquering red grape variety. Mostly found in cooler climates, the grape is chiefly associated with Burgundy in France. Pinot Noir is notably the most-planted varietal (38%) in Champagne and contributes to a large proportion of sparkling wine worldwide. Many wine regions try to replicate Pinot Noir is a difficult variety to cultivate the vines have a tendency to produce tightly packed clusters making it susceptible to several viticultural hazards involving rot that require diligent canopy management. The thin skins and low levels of phenolic compounds lends pinot to producing mostly lightly coloured, medium-bodied and low-tannin wines that can often go through phases of uneven and unpredictable aging. When young, wines made from pinot noir tend to have red fruit aromas of cherries, raspberries and strawberries which are riper in warmer climates such as the USA. As the wine ages, pinot has the potential to develop more vegetal and "barnyard" aromas that can contribute to the complexity of the wine.
