Tree Martini is an unusual version of Dry Martini—typically made with a 5:1 ratio of gin and dry vermouth—served in Spanish porrón, a glass pitcher with a long spout. The pitcher allows the drink to flow in a thin stream, directly into the mouth.
Tree Martini hails from a ski resort located north of the city of Taos in New Mexico. The cocktail was invented in the winter of 1958-59 by Ernie Blake, a ski instructor and the owner of the Ski Valley resort. The legend says that one of Ernie’s trainees struggled to get down the slope during a skiing lesson.
