Mars occasionally puts out some interesting single cask releases; these are available through the distillery's online shop and at better liquor shops in Japan, as well as at Dekantā, of course! This is very rare bottle of single casks, exclusively made for retailers. We know of only two cases, but a third exclusive bottling has been available for a few months now; it was bottled for the posh supermarket chain, Seijo Ishii, from an American white oak ex-sherry butt (cask #902). Distilled in February 1990 and bottled in November 2011, it has a whopping strength of 64.7% ABV. Bottles are individually numbered, and the out turn was 425 bottles.
