Today’s Drink of the Week needs no introduction. The timeless Italian classic that’s inspired countless riffs, the Negroni (click here for the recipe) inspired us at Imbibe to launch a full celebratory week in its honor, encouraging bars around the country to donate at least $1 of every Negroni (or Negroni riff) sold over the course of the week to the charity of their choice, giving cocktail enthusiasts the perfect opportunity to give back. Now in its third year, Negroni Week 2015 kicks off this coming Monday, June 1, and runs through Sunday, June 7, and so far more than 3,000 bars in countries across the globe have signed up. Maybe you’re a bartender who wants to get in on the giving? Or an enthusiastic imbiber who’s excited to drink for a good cause? Head to NegroniWeek.com to register your bar (submissions end tonight at midnight PST) and to get a full list of participating locales, so you know exactly which spots in your city to visit throughout the week. And be sure to follow our Twitter and Instagram feeds and the #NegroniWeek hashtag to find out how we’re celebrating throughout the week.
