This is a review of the 3rd edition of Sauvage, one which has widely been agreed to be significantly less sound in comparison to its earlier iterations. I've never tried the first or second editions, so this is coming to me without any prior comparisons in mind. Review done at 4:1 ratio, extremely slow drip and 1/2 a teaspoon of sugar.
Appearance: Crystal clear, no haze or sediment. Color is an attractive blend of olive and peridot. I wouldn't say it's jewel-like, and perhaps just a skosh dark, but certainly very attractive.
Louche: Just as a note, coaxing a good louche out of this was difficult, hence the very slow drip. There's nothing wrong with the louche, but it is not exceptional or opalescent.
Aroma: Not at all unpleasant, and during the louche the aroma blooms out nicely, but post-louche the aroma is a touch weak, with some notes of anise and a fresh, grassy note as well, but overall not particularly strong and not as inviting as it could be.
Flavor/Mouthfeel: Rather light and refreshing, like the aroma, but perhaps too much in that direction. The anise is there but weak, some fennel, a definite undertone of bitterness, though not overpowering, and some suggestions of mint. There is a very slight "off" taste, it's not prominent, but adds a less pleasant note. I wouldn't call it highly flawed, but it is idiosyncratic. Mouthfeel is perfectly acceptable.
Finish: A slight, and pleasant, burn, some peppery notes, as well. The aftertaste lingers for awhile, but it isn't particularly pleasant. Doesn't make me want to run for a glass of water, but there is a very slightly acrid note that makes it less enjoyable for certain. Only some mild numbness,
Overall: If you're looking for an absinthe that is a bit lighter on the nose and the tongue, this could work for you, except that the aftertaste is off-putting. And it's less a "feminine" absinthe and more just plain lacking. I wouldn't call it outright bad, it's certainly drinkable. But especially for the price, you could certainly do better than this.
