Château Maris considers itself to be the ‘greenest’ winery in all of France. Not only is it sustainable and biodynamic, but its cellar walls are made almost entirely of organic lime and compressed hemp blocks that naturally insulate and breath, allowing the winery to stay at the optimal temperature year round without the use of active heating and cooling systems.

I’ll try and stay far away from any poor attempts at weed puns (as hard as that may be) so as not to detract from the truly remarkable application of everyone’s favorite herb. Of coure, hemp comes from the fibrous stems and branches of the marijuana plant and not the female “cannabis sativa” we know from recreational use. Hemp has many practical applications, none more impressing then using it to create this biodynamic wall system.

After considering other organic wall materials such as stone and straw bail, hemp was picked because it is inexpensive and lightweight, making shipping and building with much easier. The Château is currently in the process of a LEED Platinum certification, and boasts other sustainable features such as using recycled bottles and paper for labeling, and donating a percentage of sales to eco-friendly organizations.
