What’s the official drink of summer? That’s up to you. We have a shortlist of summer cocktails, and you can vote for your favorite. We’ll take the top three and mix them live during CloudFest Parkside at the Cocktail Mixer, hosted by our friends at Open-Xchange. We’ll list the ingredients when we announce the winning cocktails, and you can make them along with the expert bartender at the Colosseo Bar.
