You’re having a party, but you don’t know a lot of recipes for mixed drinks. Sure, you could run to the bookstore and buy a bartender’s recipe book, but where’s the gadgety fun in that? Instead, purchase the Perfect Drink App-Controlled Smart Bartending Scale and you’ll have recipes for hundreds of drinks at your fingertips, plus you’ll have an app that can guide you as you mix. Place the included shaker, or any other glass, on the scale, select your drink, choose the serving size, and get ready to produce great drinks! The app (available for Android or iOS) will tell you what ingredient to add, and it will weigh the mixture as you add and notify you when to stop and move to the next ingredient. If you make a mistake and over-pour something, the app will automatically correct the amounts of the other ingredients to fix the drink. If you don’t have a fully stocked bar, you tell the app what you do have, and it will show you the drinks you can mix. You can even add your own recipes or variations of existing recipes to the drinks library. The Perfect Drink App-Controlled Smart Bartending Scale is available for $69.99 from Brookstone.
