The new facilities at Clerc Milon are based on a green philosophy. Energy is produced due to the 300 square meters of photovoltaic cells on the roof top. Chateau Clerc Milon lays claim to being the first vat house with HQE (High Environmental Quality) certification in the Bordeaux wine making region. The estate added a new barrel cellar which was built inside a small hill placing half the cellars underground. This keeps the cellar cold while taking advantage of the environment. Work continues on replanting the vineyards. Optical sorting is also used. All of these improvements in the facilities have clearly helped create a better wine at Clerc Milon.
