Using Portuguese ruby Port wine casks as the main flavour, Kavalan Concertmaster single malt whisky is the first matured in specially selected American oak casks and then finished in port barriques. The marrying in the barriques mellows the flavours and adds indefinable smoothness to the whisky. It is rich bodied with natural sweetness and complexity.

Because I had already had "Kavalan Solist ex-Bourbon Single Cask Strength, I could not be satisfied with this "Concertmaster". The aroma was charming and taste was good. But ... it was not "enough" because I know "SOLIST". If you have chance to try Taiwanese whisky "Kavalan" at bars, please try "Solist ex-Bourbon CASK Strength". I am sure you will become a fun of it.
