The average age of the vines is 40 years with some Syrah and Cabernet Sauvignon being in excess of 70 years old. The most recent plantings were carried out in the 1990s. There are between 3,600 and 4500 vines planted per hectare, with a space between the rows of between 2.1 to 2.5 metres. The vines themselves are either 'en gobelet' or on a trellised double cordon. Each vine is pruned to four spurs with two buds on each spur. Increasingly the emphasis has been on organic viticulture that has resulted in a steep reduction in the amount of herbicide and pesticide used, resulting in a greater emphasis on 'working the soil'.
