Robert Eden, "bio-dynamic wine maker" as he describes himself on their website, has been working in the Languedoc for many years now and set up Château Maris 15 years ago, backed by Kevin Parker of Green Partners. They're obviously very committed to environmentally friendly wine production - Demeter certified since 2008, Biodyvins in 2004 (both for biodynamics), Ecocert in 2002 and the National Organic Program - and there's a fair amount of detail on this on their site: click on web link under the photo (Robert with one of their vineyard horses). But to try and go 'all the way' organically, in terms of carbon emissions, water and energy sustainability etc., they also built "the world’s first hemp cellar." Before you spliff-heads out there get too excited, this means they used hemp and lime bricks, which apparently continue absorbing CO2 for many years "as the lime solidifies into limestone," and a lot of raw wood from sustainably managed forests. They claim these materials also provide excellent natural insulation, while being able "to breathe" at the same time...

2011 Maris Organic Minervois (mostly Syrah, Grenache) - lovely pure spicy violet and black cherry aromas, tasty fruit with fairly easy-going tannins, nice ripe vs peppery finish. €7.80, £59.94 for six.
2010 La Touge Minervois La Livinière (85% Syrah, Grenache, Carignan) - similar pure spicy Syrah style fruit on the nose, punchier and more structured though, attractive dry tannin vs sweet fruit texture, fresh bite and good length. €12.40, £89.94 for six.
2010 Continuité de Nature La Livinière (90% Carignan, Grenache) - jammy blue fruits lined with fresh acidity yet powerful too, concentrated and tight palate, very different from the above wine considering it's the same vintage, leaner and longer; probably more versatile with food though. €21.60, £119.94 for six.
2009 Nouvelles Fraiches Grenache - 'oily' sweet liquorice notes on the nose, ripe and rounded mouth-feel, quite punchy, fades a little in the end. €16.60
