The limited-release Johnnie Walker Double Black label is to expand beyond duty-free shops in March 2011, according to a September 29 announcement from Diageo, a London-based global alcoholic beverages company, via beverage industry resource Just-Drinks.

Johnnie Walker Double Black's Facebook page outlines that "[t]he whisky was created taking Black Label as a blueprint and adding heavily-peated malts and some aged in deeply charred oak casks.

"The one litre bottle of Johnnie Walker Double Black will retail at a +15-20% price premium to Johnnie Walker Black Label even though it has No Age Statement." Johnnie Walker Black is a blend of 40 12-year or older Scotch whiskies and is priced between €36-59.

The global director of Johnnie Walker, David Gates; said, "Interest in the Scotch whisky category continues to be high and we believe consumers want to explore the huge range of flavour experiences that a brand like Johnnie Walker can deliver."

Until March bottles are still available at international airports and duty-free shops in Beirut, Singapore, Bangkok, New York (JFK), and Sydney.
