We had the Hermes, Benoit-Serres, and Rothman & Winter liqueurs.
Boy, they are different.
The Hermes is the sweetest and most candy-like of the bunch. Apropos of jmfangio's comment above, several folks unfamiliar with this topic remarked that it tasted like violet pastilles dissolved in liquor. The initial flavor I got was similar to marshmallows, then violets.
The Benoit-Serres the next sweetest. Stronger violet taste, with some tropical flavors in the middle taste sensations.
Finally, the Rothman & Winter was the least sweet. Earthy, intense, perfume-like, violet flavor with few additional elements.
edit - Oh, yeah, being the fuddy duddy that I am, I made classic style Aviations: 1 1/2 oz 209 Gin, 3/4 oz Lemon Juice, 2 dash R&W Violet, 1 dash Maraschino. Not bad and received generally favorable comments. I thought the 209 a little lacking in gin-i-ness compared to the Plymouth I usually mix Aviations with.
