Organic Winegrowers

The Castagné brothers are winegrowers on 4ha of vines. The plots are planted on a hillside facing southwest. Our vines are certified by organic farming and are located high up in the woods, isolated.

Maison Castagné produces wine under the appellation Vins de France. No PGI is present in the territory, the closest being Cahors. It produced 24,000 bottles of wine from the 2021 harvest, in white and red.

Martel was once an important wine-growing land, which disappeared with the phylloxera around the 1870s. Wishing to revive this heritage, the Castagné brothers planted vines in Loupchat, 800m from the mill.

   What is a living wine ? 

Organic vineyards

Working in organic farming, the vines express the passion for the terroir by its winegrowers. A living wine comes from a grape that has not been in contact with any chemicals. The use of fertilizers or pesticides is strictly forbidden! We work the vineyard mechanically, with the tractor without weeding. With a view to becoming ever closer to the natural cycle of our environment, we have set up a system of green fertilizer that resows.

Neither glued nor filtered

Thats good, but what does that mean? After fermentation, gluing involves removing suspended particles from the wine by adding a gelatinous product, such as egg white, which has been used for many centuries. Filtering, on the other hand, consists in removing impurities to have a moreprettywine aesthetically speaking.

Then why stop? Because it makes it lose some natural flavors. The wine is cloudy and it disturbs, but its quality is there!

Goodbye water and sugar!

The grapes vinify themselves, like a big one, thanks to the native yeasts. Native yeast? These are microorganisms (or fungi) present on the grapes at the time of harvest and are responsible for the fermentation of the fruit. The only permitted input for natural wines is sulphur dioxide (S02), which is useful for the preservation of wine. We touch the wine as little as possible, there is only one extraction. Depending on the turbidity of the wine, we carry out a light filtration on cellulose.

Why do we do this?

Because the addition of inputs, or additives, changes the taste, character, texture or colour of the wine. In other words, they make it up! Abuse of pesticides, dyes, preservatives, acidifiers or flavour enhancers. . . Classic wines are as beautiful as a supermarket tomato but nothing will match the one from your garden, right?

So, will you be tempted by a natural wine?
