2013 Petrus, Pomerol, Bordeaux

The most widely planted grape in Bordeaux and a grape that has been on a relentless expansion drive throughout the world in the last decade. Merlot is adaptable to most soils and is relatively simple to cultivate. It is a vigorous naturally high yielding grape that requires savage pruning - over-cropped Merlot-based wines are dilute and bland. It is also vital to pick at optimum ripeness as Merlot can quickly lose its varietal characteristics if harvested overripe.

With 150 or so producers and roughly 740 hectares of vineyards, the smallest of Bordeaux's major appellations is home to myriad bijou domaines – many making little more than 1,000 cases per annum. If the topography and architecture of Pomerol are typical, the style of its wines is anything but. The best vineyards are planted on a seam of rich clay extending across the raised plateau of Pomerol from the boundary of St Emilion.

Petrus is a wine estate in Pomerol on the Right Bank of Bordeaux. It is among the most celebrated and recognisable wines in the world.
