Organic production methods on the increase in the Medoc

Thursday 22nd February 2018

A recent study of levels of residues from chemicals used in the vineyards in 38 classed growths of the Médoc has highlighted the growing trend towards organic and bio-dynamic wine production in the region. Although most of the wines tested still had some residues from the fertilisers and pesticides used in growing the grapes, a comparison with four years ago showed that the numbers of different elements found and their levels of concentration in the wine are both around a third of what they used to be.

While Ch Pontet-Canet is still the only Médoc classified growth to be certified as 'Biologique', many chateaux are moving in that direction. Enthusiastic growers of organic wines will tell you that their wines have a much cleaner, fresher taste in the mouth. Many will disagree, but this survey shows that, quietly, most chateaux are reducing their use of chemicals and it is anticipated that several more classed growths will 'come out' as organic in the not-too-distant future.

Mouton Cadet, one of the biggest selling brands of Bordeaux wine, which uses grapes from all over the region in its blend, and may therefore be thought to be fairly representative of the region, was found to contain 3 different residues, compared to 14 when it was last analyzed.

In the meantime, Ch Durfort-Vivens in Margaux, and Ch Pontet-Canet in Pauillac, can rest on their laurels as the only completely residue-free Medoc classed growths!
