Domaine Michel Vattan 
Back to producers by region list


This family-style operation started out in 1930 with 2 hectares of vines, mixed crops and livestock but progressively grew to 9 hectares of vineyards only during the expansion of the Sancerre region’s vineyards that began in 1970 and continues today. The estate consists of 7.8 hectares of Sauvignon Blanc and 1.3 hectares of Pinot Noir divided between 2 principal types of terroir :  Caillottes and Terres Blanches, which benefit from southern and north-western exposure respectively and are typical of Maimbray’s hillsides.

Soils and Farming practice

 Michel Vattan and Pascal Joulin became partners in May 2008 in preparation for Michel’s retirement. Pascal has worked at the estate since 2002, and the objective under this new management structure is for the estate to sell primarily bottled wine. Limiting yields, growing crop cover between the rows of vines in most of the estate’s vineyards, and not using insecticides for several years now are all factors that ensure the quality of the wines which respect both the typicity of their appellation and the environment.




  • Words of the vigneron regarding the farming practice :
 "Following ten years of preparation, all of our plots have had cover crops, mainly grasses and dwarf clover, growing between the rows of vines for the last several years. For the middle-aged and older vines, we let the natural vegetation grow under our control while for the younger vines we sow seeds for selected cover crops in order to allow the root systems to develop under optimal conditions. We no longer use herbicides that prevent germination and we cut the cover crops two or three times a year depending on precipitation levels. Since the vine roots and grass roots compete aggressively for nutrients, we supplement the soil with organic matter, in proportions adapted for each plot depending on its nutritional needs to ensure optimal ripening of the grapes.

We no longer use insecticides because the fauna and flora present in our vineyards are naturally balanced and regulated. In some of our vineyards grapevine moths are managed naturally through the use of sexual confusion. Our approach to spraying is adapted according to the risk of disease and to precipitation levels which vary each year. We have found that reverting to the use of copper and sulfur-based products is sufficient, and the use of products to combat botrytis is less and less justified in our vineyards due to controlled yields."

The Terroirs

  • Terres Blanches
  • Caillotes
  • Terres Blanches
Located higher up the slope from the caillottes, the soil in these vineyards consists of Kimmeridgian marls. These formations are found at the top of some hills and on the main slopes. This type of soil is extremely rich in shellfish fossils and has the distinctive characteristic of turning white when it dries,
hence its local name, les terres blanches (white earth). The wines produced from grapes grown in this type of terroir are soft and full of aromatic finesse. They require more time to acquire all of their character. As part of a blend, they often provide the backbone of the wine due to their complexity and power.

  • Caillotes

This type of terroir consists of fragments of coarse Kimmeridgian limestone that give way in some areas to softer Oxfordian limestone that produces finer fragments known as griottes or very fine fragments called grous which are wind deposits. Oxfordian limestone from the Jurassic Period is found
in the form of a bed of white stones that are flat as they were shattered by frost. Rain washed the surface earth away, leaving the little stones or caillottes
that are so characteristic of Sancerre’s hills visible at the surface. Wines produced from grapes grown in this type of soil are nervous, fruity and pure.
They may be enjoyed immediately (between 6 months and 1 year). They lend aromatic structure and freshness when part of a blend.

About Sancerre

East of Bourges, the Sancerre appellation is located along the left bank of the Loire River, stretching across 3,000 hectares (7,413 acres). This appellation extends over the villages of Bannay, Bué, Crézancy, Menetou-Ratel, Ménétréol, Montigny, St-Satur, Ste-Gemme, Sancerre, Sury-en-vaux, Thauvenay, Veaugues, Verdigy and Vinon.
Three types of soils are characteristic of the Sancerre region:

· Clay and limestone white soils, (terres blanches) situated on the hills of the most western part of Sancerrois
· Pebbly soils, known as caillottes
· Siliceous-clayey soils found in the hills east of the vineyard
