Geographical location of Maison Bollinger
At Bollinger, great importance is attached to the natural, organic character of the vines. The soil is grassed and herbicides are avoided as much as possible. These efforts have earned Bollinger the "Haute Valeur Environnementale" certification. The 172 hectares of vines are planted with Pinot Meunier and Chardonnay. The soil is composed of Campanian chalk, chalk gravel, thick hard limestone, Belemnite chalk and Sparnacian clay, all in varying proportions. When it comes to winemaking, wood is of paramount importance. Indeed, the Bollinger family employs the champenoise vinification method. Thermo-regulated stainless steel vats are used. Depending on the ability of the musts to hold wood, under-wood vinification using oak barrels is employed for all or just a portion of the cuvées. Malolactic fermentation is used for white wine cuvées. The bottles are stirred by hand on a wooden rack, 1/8 to 1⁄4 of a turn. After aging on laths, the deposit is expelled by disgorging on the fly.
