Formerly known as Alba Reserve, they have changed the name for transparency and simplicity of trade and consumer understanding. A certified Kosher expression it is matured exclusively in American oak ex-Bourbon casks.
The Glenrothes' normal wood policy uses a combination of Spanish and American oak, seasoned with sherry, bourbon and malt Scotch (known as refill). Of those only Bourbon is 100% Kosher.
For this expression Gordon Motion has used Glenrothes matured exclusively in American oak refill Bourbon casks. It therefore delivers coconut and vanilla in abundance, and is soft and mellow with a crème brulée flavour and feel.
Bourbon Cask Reserve was certified in March 2009-and annually thereafter-by Rabbi Padwa of the London Beth Din.
