The Balvenie DCS Compendium Chapter Two features five extremely rare single-cask single malt whiskies and highlights the complex manner in which different oak casks influence the flavour of The Balvenie during the maturation process. David Stewart MBE pioneered double cask maturation, or finishing, during his career at The Balvenie and this chapter showcases his vast knowledge and understanding of this process. The whiskies in Chapter Two, range in age from 15 years to 43 years, with each of the casks chosen by David imparting their own distinct flavour profile to the final expression.
