Château Mouton Rothschild is one of the five First Growths of Bordeaux and is arguably one of the greatest wine 'brands' in the world. They also produce a limited volume of spirits too.
In their own words: "Every year, several barrels of young wine produced from the vineyards of Chateau Mouton Rothschild are destined to become Eau-de-Vie. The traditional process of double distillation in an Alambic copper still creates a spirit with fine, rich aromas. The Eau-de-Vie is aged in oak barrels for a period of 15 to 30 years. Six months before bottling, Eaux-de-Vie of different ages are blended, with the average age being about twenty years."
