As a description of the event explains, "There are 3 types of tears; basal, reflex and psychic tears. We will aim to extract all three by various methods, from massage and menthol, in order to distil [sic] the finest bottle of bitters. Then you’ll select your aromatic herbs and spices and infuse or tincture them in high proof spirit."
To be clear, this is almost certainly not what Harry Potter was planning when he collected Severus Snape's tears in the last book. Also, just think of all the tearful takes on classic cocktails you can create for your friends and family -- things like the Sad Fashioned, the Ne-groaning, the Pisco Sour Sour, and the Sad-zerac. Sound delicious, right?
But regardless of how you feel about drinking your own or someone else's tears, it's probably best not to knock it 'til you cry it.
