The latest Japanese/import malt whisky blend from Mars Whisky is a limited edition dubbed Mars Maltage "Cosmo" Manzanilla Cask Finish.
As the name shows, they've simply taken the standard Mars Maltage "Cosmo" and finished it in an ex-Manzanilla sherry cask. Per the tasting notes, this builds on the soft and smooth mouthfeel of standard Cosmo, adding aromas of dry fruit, brown sugar, and maple syrup from the cask, chocolate and coconut in the palate, with a slight bitterness.
At this very moment it's still in stock for 5400 yen on Amazon JP, but I don't expect the stock to last long. 42% abv, 700ml.
