The appellation of Sancerre is part of the 'central vineyards' of the Loire Valley, with almost all of the appellation situated on the left bank of the Loire River, opposite Pouilly Fume. This region has a continental climate, as it is some 400 kilometres from the Atlantic Coast, with short, hot summers and long, cold winters. Early spring frosts are an annual threat in the vineyards. These vines are grown in chalky soils, providing good drainage. Domaine Gerard Millet holds the Haute Valeur Environmental (HVE) certification, which officially recognises the environmental performance of winegrowers, including biodiversity conservation, plant protection strategies, managed fertiliser use and water resource management.
