Ecological pillar
Drawing inspiration from the way ecosystems function
to preserve the environment and resources
Living soil
With common sense and pragmatism, we reason our viticulture from the soil to the plant. This means making the greatest possible effort to maintain a living soil. One cm3 of soil contains several billion living organisms. Mushrooms, bacteria, earthworms and insects all contribute to the proper functioning of our soil, which we regard as a larder. We respect it as such by never ploughing it, by covering our vine rows with plant cover which is destroyed on the surface. They structure and aerate the soil, provide organic matter (food for the inhabitants) and protect it from the wind, sun and heat.
Finally, we regularly add calcareous marl to maintain a good chemical balance.
Encouraging biodiversity
Our plant cover is rich in melliferous plants: red clover, sweet clover, buckwheat and broad bean attract insects and, by extension, birds. Similarly, small mammals and reptiles populate our vines thanks to the food available and the habitat encouraged and preserved by our practices. Beehives set up on the edge of our plots also contribute to the vigour of the environment.
This biodiversity is also stimulated by the many trees on the estate. From the practice of agroforestry to the agro-ecological park encompassing woodland, copses, meadow strips, ponds and wild open spaces, trees are at the centre of our thinking and are our major asset for regulating the environment and absorbing climatic hazards as effectively as possible.
Our aim in promoting biodiversity is to maintain a healthy, balanced and resilient growing environment. Our vines sometimes face competition, but this strengthens their defences and their ability to adapt. We seek balance for our grapes, so that they are perfectly ripe at harvest time and reflect the terroir and the vintage.
Preserving water resources
The climatic context encourages us to consider water as an essential element of our agricultural system. Too much rain all at once, not enough in winter, summer drought, wet winter, etc. The water situation is far from linear.
We collect the rainwater that falls on our winery to carry out our treatments during the growing season.
Our soils, which are covered and protected from intrusive mechanical work, are capable of absorbing water as it falls and storing it so that it can be released over time, as our vines need it.
Trees are also an invaluable tool for managing water resources. They structure the soil, allowing infiltration and capillary rise according to the needs of the crop.
Energy sobriety
Our agro-ecological practices enable us to store 240% of our carbon emissions for the production of our grapes in the soil. However, we are constantly thinking about how to optimise our energy consumption. Our agricultural work is rational and economical, in terms of the number of operations and the tools we use. Our tractors consume very little fuel, and we use horse-drawn vehicles to reduce our consumption even further.
Finally, elbow grease is a remarkable way of reducing consumption! Pickaxes, hoes, spades, rakes and backpack sprayers are our everyday tools.
Economical pillar
Reclaiming an inclusive economy serving the common good
Local employment
Our approach is global and sustainable. We give priority to human and artisanal work, which shapes the landscape and maintains our estate. We welcome many students on work placements, who are always fully involved and help us to move forward and think things through. Our team is close-knit and close-knit, always ready to meet the challenges of day-to-day work and long-term projects.
A sustainable estate
All our practices are part of a sustainable approach. And on our scale, sustainability has to be economic. Whether it’s a question of developing our business by offering high-quality products, or paying our employees as well as we can, but also of taking pleasure in giving our time and energy to tending the vines and making our wines, our aim is to build a viable estate, i.e. one that has what it takes to last.
Social pillar
Cultivating solidarity and social responsibility through an ethical and supportive approach
Small-scale farming on a human scale
Our practices are far from revolutionary, but they sometimes make our neighbours, walkers and professionals sit up and take notice. Yet we are guided by good farming sense, based on observation, consultation, listening and exchange. We take part in regular training courses, focus groups and technical bodies. We plan our plots so that they make sense: orientation, grape varieties, pruning.
Sharing skills and knowledge across the board
The whole of the estate’s team is involved on a daily basis in the issues surrounding our committed viticulture. Weed and plant cover management, the plants used in our sprays, gentle pruning, the maintenance of complants, etc. Every action must make sense to everyone. Decisions are discussed and taken with the help of everyone’s input and skills.

🇫🇷 Les vendanges 2025 battent leur plein au Domaine Les Trois Toits ! 🍇
Notre cépage fétiche, le melon de Bourgogne, est désormais entièrement récolté, pressé et déjà en pleine fermentation. Ce millésime 2025 s’annonce d’une grande richesse et promet des cuvées d’exception.
Amateurs de nos cuvées Muscadet, Phileas, La Plage ou Rooftop, préparez vos papilles… Quelque chose de beau se prépare dans nos chais !
Un grand bravo à notre équipe de vendangeurs, qui se plient en quatre (et surtout en deux 😉 ) pour ramasser chaque grappe à la main - une garantie de qualité que vous retrouverez bientôt dans vos verres.
Et ce n’est pas fini : nos raisins rouges arrivent à maturité et ne vont pas tarder à rejoindre la fête.
Restez connectés pour la suite de l’aventure !
🇺🇸 The 2025 harvest is in full swing at Domaine Les Trois Toits! 🍇
Our favorite grape variety, Melon de Bourgogne, has now been fully harvested, pressed, and is already in full fermentation. The 2025 vintage promises to be rich and exceptional.
Fans of our Muscadet, Phileas, La Plage, and Rooftop wines, get your taste buds ready... Something wonderful is coming out of our cellars!
A big congratulations to our team of harvesters, who bend over backwards (and especially double over 😉 ) to pick each bunch by hand—a guarantee of quality that you will soon find in your glasses.
And that`s not all: our red grapes are ripening and will soon be joining the party.
Stay tuned for the rest of the adventure!

🇫🇷 Nos jeunes plantations observent calmement leurs voisines plus âgées mûrir. Leur tour viendra — dans quelques années, elles aussi seront prêtes pour les vendanges !
Sur cette photo, vous découvrez notre parcelle de Villard Noir, un cépage naturellement résistant au mildiou, qui nous offrira bientôt de beaux vins rouges.
Nous, on a hâte de le goûter… et on espère que vous aussi !
🇺🇸 Our young plantations calmly watch their older neighbors mature. Their turn will come - in a few years, they too will be ready for the harvest!
In this photo, you can see our plot of Villard Noir, a grape variety naturally resistant to mildew, which will soon be producing fine red wines.
We can`t wait to taste it... and we hope you will too!

🇫🇷 Aux Trois Toits, les idées ne manquent pas — et celle-ci, on y tient tout particulièrement : faire cohabiter vigne et arbres, au plus près 🌳.
Depuis notre reprise du domaine en 2019, nous travaillons à reconnecter nos vignes avec la flore et la biodiversité qui les entourent, notamment à travers la plantation d’arbres. Sur cette parcelle, nous allons encore plus loin : nous avons planté de jeunes ceps au pied même des arbres déjà présents. C`est la vigne mariée.
Les rangs seront complétés dans les prochaines années, pour donner naissance à une parcelle atypique, chargée d’histoire et riche d’un équilibre naturel unique.
Il faudra du temps avant d’en déguster les premiers raisins… mais l’énergie et la vie qui se dégagent déjà de cet endroit nous donnent l’eau à la bouche.
🇺🇸 At Les Trois Toits, there`s no shortage of ideas - and this is one we`re particularly keen on: bringing vines and trees closer together.
Since taking over the estate in 2019, we`ve been working to reconnect our vines with the flora and biodiversity that surrounds them, notably through tree planting. On this parcel, we`re going one step further: we`ve planted young vines at the very foot of the trees already present. This is the married vine.
The rows will be completed over the next few years, giving rise to an atypical parcel, steeped in history and rich in a unique natural balance.
It will be some time before the first grapes can be tasted... but the energy and life that already emanate from this place make our mouths water.

🇫🇷 Travail des sols des nouvelles plantations 🌿.
Avant de planter une nouvelle parcelle, nous semons du sarrasin l’année précédente. Cette culture temporaire améliore la structure du sol, limite l’enherbement et favorise la biodiversité, une étape essentielle pour préparer le terrain à de nouvelles vignes.
À l`automne, nous allons amender en compost et semer de nouveaux couverts végétaux pour un apport optimal de matière organique.
Ce sont des pratiques simples, efficaces et durables, pour accompagner notre vigne dès le départ.
🇺🇸 Soil preparation for new plantings.
Before planting a new plot, we sow buckwheat the previous year. This temporary crop improves soil structure, limits weed growth and promotes biodiversity - an essential step in preparing the ground for new vines.
In autumn, we`ll apply compost and sow new plant cover crops for an optimal supply of organic matter.
These are simple, effective and sustainable practices to support our vines right from the start.

🇫🇷 Les Trois Toits vu de derrière 😉.
Sur cette nouvelle parcelle, nos jeunes plants sont soigneusement attachés à leurs tuteurs. Un geste important pour les aider à bien grandir, droits et solides.
Et pendant ce temps-là… nos vignerons se plient en quatre (et en deux !) pour que tout soit bien fait. Oui, le dos en prend un coup, mais c’est pour la bonne cause !
🇺🇸 Les Trois Toits seen from behind.
On this new plot, our young plants are carefully tied to their stakes. An important gesture to help them grow straight and strong.
And all the while... our winemakers are bending over backwards (and forwards!) to get everything right. Yes, it`s hard on the back, but it`s all for a good cause!
