It’s a week night. You need a drink. Not a scotch neat, rather a sophisticated blur sans the hangover and chagrin. Your answer: Fernet Branca, a liquid masterpiece invented in 1845 in Italy containing 27 different herbs and spices originating from four continents-yes that’s a hint of Ethiopian myrrh and perhaps Persian saffron as well. If you live in San Francisco or Argentina, you already know. But if you live in New York? The mixologists at Macao Trading Co in Tribeca are respected artists of the drink. Get it on. Tell ’em supply&demand sent ‘cha.
