The deceptively simple martini is endlessly customizable and for National Martini Day, No.3 Gin invites drinkers to discover a serve perfectly crafted to their preferences with The Martini Fitting Service. The limited-time experience at Electric Space London offers an exploration of the decisions that make a great martini, from dilution and preparation methods—shaken or stirred—to ratios and garnishes.

This experience to demystify the martini promises to provide adults with an appreciation of the history of this classic cocktail, and the exact elements to help them enjoy martinis made to their tastes. A martini can be enjoyed wet with extra vermouth, dry with just a whisper of it, perfectly balanced 50/50, and finished with a twist of lemon or a briny olive, and those who already know their go-to order can take their specifications to on-site Martini Tailors.
