(Decanter) - Nine Pomerol chateaux are celebrating a victory over hugely unwelcome changes in appellation rules. Under the new rules, published in 2009 and coming into effect in 2019, all winemakers who were bottling an AOC Pomerol wine would have to produce the wine from a chai, or cellar, within the appellation. This meant that 23 chateaux which did not have winemaking facilities within Pomerol would have to construct them by the 2019 deadline, or risk no longer being able to produce a Pomerol wine. The group, the Bannis de Pomerol, consisting of nine of the excluded chateaux, appealed to the Conseil d’Etat, the highest administrative court in France, and has won a reprieve.
