LOUIS XIII Rare Cask 42.6 signalled its distinction with an alcohol degree beyond the expected 40 percent, 42.6 degrees. But the level of alcohol is merely a signal. What sets a Rare Cask apart is the quite astonishing richness and intensity of its flavours. At the heart of the composition are those prized autumn flavours of nuts and dried fruits – the long-aged flavours for which LOUIS XIII is renowned - no surprise since this cask is by its nature born to the LOUIS XIII tradition.
