Highland Park Full Volume Single Malt Scotch Whisky - 750MLFULL VOLUME was created using 100% ex bourbon casks rather than our traditional sherry seasoned ones. During 1999, a combination of 481 casks 200 litre barrels and 250 litre hogsheads were filled at strengths of between 63. 6% and 63. 7%. The whisky was filtered at just over 4oC and delivers flavours of creamy vanilla and sweet citrus fruits from the bourbon casks, balanced by Highland Parks characteristic aromatic smokiness.
