H. Ehrmann knows his cocktails. He has a deep knowledge of not only ingredients and the process of making fantastic cocktails, but the history and lore that add great context to the art of mixology. Plus he has a wicked sense of humor and really seems to be able to connect with his class in a way that makes really fun and non-stressful. One of the best aspects of the class is watching the other participants get friendlier and louder with each drink made ;) It is a really good idea to plan for a pre-class meal, as the drinks will begin to creep up on you! Thanks for the killer experience, H.!
