St. Germain Elderflower Liqueur is 20% abv. / 40 proof artisinal French liqueur that is available in limited quantities. It is a very light pale gold color and a medium light body. The aroma is primarily flowers and fruit, think of pears and lychee, and is lightly sweet and tart on the nose. The taste is like the aroma, very floral plus lychee's and pears, with maybe the slightest hint of citrus. It has a refreshing tartness up front, a mild sweetness in the middle, with a long finish of the two combined. The taste and smell stays with you for quite a while, filling you mouth and nose with its luscious fruit and flowers.
St. Germain is an absolutely delightful liqueur and since it isn't too sweet I find that even people who dislike most sweet liqueurs enjoy it very much. While it is an elegant liqueur for sipping straight or on crushed ice for a post meal libation,
it also is fabulous in cocktails.
The elderflower has been used for medicinal purposes for ages and so it has also been available in syrup form for quite a long time. Many bartenders have also used it in various cocktails, but St. Germain is the first elderflower liqueur / spirit. Released in the US early last year, it is created from fresh picked elderflowers which are macerated / infused in eau de vie and/or distilled (the process is secret, of course), plus small amounts of citrus, and sweetened just a little.
