Nature and wine 

 

AREA integrated vineyard management certification, controled by "Chambre d'agriculture de la Gironde" : beyond obtaining a piece of paper, what practical measures are we implementing ?

- reducing or even eliminating vineyard inputs (chemical fertilizers, synthetic pesticides, weed-killer), preferring cover crop around the vines or just let some weed cut, amending with organic fertilizer and only ploughing occasionally (twice per year between alternate rows) to loosen and aerate the soil, without destroying our friends the earthworms. These practices may result in up to a 20% decrease in yields, depending on the year, as for example in 2016 ;

- preserving some wild areas on the estate, such as woods or copses, and natural hedges formed of old oak trees. Consequently, a wide variety of flora and fauna may be observed in our vineyards, including a local species of wild orchid. We also lose at least 5% of our harvest to game animals and birds every year, indeed, our vines are not fenced so they can pass through ;

- reducing the inputs in wine : using natural, "indigenous" yeasts, while certain treatments, such as desacidification and earth filtration are completely prohibited in our wines ;

- compliance with good agricultural practices when using pesticides : untreated areas, little or no wind when spraying, good temperature depending on the time of day so that the bees can live in peace, protecting workers : delay after spraying before working in the plot again, it would take too long to give all the details ;

- preserving water resources : equipment washing area and rainwater recovery (2010), temperature-control system in the winery (1993), 50% reduction in weed-killer in our vineyards (1995), 50% reduction in weed-killer in our vineyards again (2016), elimination of back-labels from our bottles (2015), bottle more light : less glass (2017), etc...

This all contributes to our efforts towards responsible, sustainable agriculture.
