Whisky Johnnie Walker Blue Label Elusive Umami. Capitalizing on the reputation of the unrivaled Johnnie Walker Blue Label, Johnnie Walker Blue Label Elusive Umami is characterized by even greater complexity and rarity, as only 1 in 25,000 barrels meet the criteria of seeking this elusive flavor profile. It is a carefully balanced drink that combines sweet and salty notes, encapsulating one of the most indefinable flavors in the world. This seductive drink is ideally served straight, accompanied by caviar, which reveals the full depth of this unique experience for the senses. We recommend the sturgeon caviar because it has a strong Umami and metallic character.
