It’s all in the delivery, and how you carry yourself off, not what you actually say.
Stick your nose into the glass. Sniff deeply, then close your eyes as though you’re processing a lot of things simultaneously. Even if you smell nothing, act as though this drink is a cornucopia of sensations and you’re sorting through all of them. Do not speak. Scent is pretty easy to verify, so if you guess wrong then everyone will know what a yutz you are. If someone ventures their own review as to what it smells like, frown as though you’re too busy concentrating on this intense bouquet to interrupt it with stupid words. This automatically gives you the edge, since as a conneisseur you know enough not to discuss anything until the full tasting is over.
