From Luxist:

Diageo Global Travel and Middle East has launched a 21-year old
Johnnie Walker Scotch whisky exclusively, for now, at Indira
Gandhi International airport's newly opened Terminal 3.

Johnnie Walker XR 21 YO is an exclusive blend inspired by the handwritten
notes of Sir Alexander Walker, the grandson of founder Johnnie Walker.
Sourced from the exclusive reserve of aged casks, including those of the
now silent Brora distillery, the whisky has been allowed to age for
twenty-one years, achieving a smooth, deep blend - the depth and
intensity of aged oak, the subtle notes of vanilla, the sweet hint of golden
honey and a very smooth finish. Each bottle is uniquely numbered and sells
for $105.00 U.S.

Diageo is quiet for now about a broader release.
