Hold the door open for the person behind you. Look people in the eye when you shake their hand. Never talk politics, religion or money at a dinner party. Yes, Ketel One is the vodka that brings out your inner gentleman. We took this “gentlemanly” essence and brought it into the modern age with the launch of one of the first branded spirits apps, then hammered it home with some sharp sponsorship and retail posters. Oh, and always remember to send a thank you note to your host (especially if you spilled a dirty martini on their living room rug).
