For the third time in history, in an unexpected departure from the ordinary passage of time, Cellar Master Baptiste Loiseau uncovers the third milestone in the Rare Cask legacy: Rare Cask 42.1. Inexplicable and unpredictable, a single tierçon has just unveiled its uniquely exceptional aromatic profile, giving a distinct expression of Louis XIII Cognac never encountered before, and with an unexpected 42.1% ABV. Rare Cask story begins in 2004, when Cellar Master Pierrette Trichet identified a centennial tierçon of eaux-de-vie with a richness and intensity never encountered before and an exceptional 43.8 degrees ABV. This became the first Rare Cask, so special that only 786 black crystal decanters were released. The second Rare Cask was launched in 2013 with a yet different ABV of 42.6. Today, Louis XIII unveils its third ever special edition with Rare Cask 42.1.
