The Clos du Tue-Bœuf family estate was taken over at the beginning
from the 1990s by the Jean-Marie brothers (now in
retirement) and Thierry Puzelat, and it is now led by
Thierry and his daughters Zoé and Louise. With 10 hectares in the Cheverny appellation and 4 hectares in the Touraine appellation, this is undoubtedly a pioneering estate for organic and "natural" wine in the Loire Valley, following in the footsteps of Jules Chauvet and the experiments of winemakers Marcel Lapierre (Beaujolais) and Pierre Overnoy (Jura). The estate's philosophy is based on defending the true expression of the terroir against all artifice and is reflected in about ten different cuvées, each reflecting the specific geological characteristics – flinty clay or siliceous gravel – and the grape varieties associated with them. Among the white wines, notable examples include Frileuse (Sauvignon Blanc, Fié Gris, and Chardonnay), Le Brin de Chèvre (Pineau), and Le Buisson Pouilleux (Sauvignon Blanc). The reds include La Butte (Gamay), Rouillon (Gamay and Pinot Noir), La Guerrerie (Côt and Gamay), La Gravotte , and La Caillère (mostly Pinot Noir). These wines have become iconic and inspire many young winemakers seeking authenticity.
