The St. Germain's Elderflower Liqueur is pretty much the favorite thing in my bar. It goes in almost any drink and gives it a great flavor profile.
Pincer vodka not only has that same elderflower taste but also milk thistle and is combined with grain vodka to produce, what they claim to be, an almost hangover free vodka. The healing powers of elderflower and milk thistle are two items that are supposed to help you get up a little easier in the morning.
The product is about to launch in the UK with no pricing set as of yet.
