A secret distillery refers to a producer of whisky or other spirits whose exact identity is not revealed on the label. This may be done to protect the recipe, craftsmanship, or origin, or to create an aura of mystery and exclusivity. These bottlings are often made by independent bottlers, who select unique casks and emphasize the region or style rather than the distillery name. Enthusiasts can often identify the producer through aroma clues, malt typicity, and cask records. The appeal of a secret distillery lies in its rarity, originality, and sensory discovery, turning each tasting into a unique and mysterious experience.

Swell by Spirits is created in 2021 by Michael Barbaria. Its bottlings come from a meticulous selection of exceptional barrels in collaboration with each producer, to which it pays homage by succeeding in captivating the most discerning taste buds of enlightened amateurs. Its bottles, with a design just as original as the liquid they contain, make Swell de Spirits a key player on the independent scene.
