The one I liked most was the Tempus Fugit.
The Liqueur de Violettes, from impressive newcomer Tempus Fugit Spirits, is yet another fine quality and highly individual spirit, and is busily attracting attention from serious bartenders. Less sweet than the other two (it is labeled as a ‘liqueur’, not a ‘crème’), this Violette is a pure, delicate, brightly floral liqueur without being cloying and oily on the palate. Some floral botanicals leave a soapy residue in the finish; the Tempus Fugit doesn’t; the finish is fresh and clean. At 44% alcohol, the liqueur asserts itself, lingers in an appealing way, and leaves you with a fond memory of violets rather than cheap perfume. It is ideal for an Aviation Cocktail: floral, pretty in a pink-purple hue, and delicate enough to allow the complex botanicals of the gin to shine through.
Obviously, violet liqueurs aren't a high demand/high volume kinda thing...but if you make Aviation cocktails or just like violets, this could be your thing.
