Islay single malt is the penultimate smoky Scotch in the whisky world. Intens, clashing tastes and a rough and tumble experience. Smokehead Extra Rare is such a smoky single malt, sourced from an undisclosed distillery — although there are lots of rumors doing the rounds. Smokehead Extra Rare is originally a travel retails exclusive, but now available outside of airports. It offers tons of flavor.
