Any drink. Any size. Perfect Drink. A revolution in home bartending, Perfect Drink's smart scale and free app let you choose from hundreds of drink recipes, follow real-time pouring instructions, and watch as a virtual glass fills on your smartphone or tablet. That way, you know exactly how much to pour and when to stop-for perfect drinks, every time. Perfect Drink lets you choose any serving size, so you can make everything from single serving to party pitcher. Place any container on the scale, and it automatically sets itself to zero so you're ready to pour. The "smart scale" automatically weighs each ingredient as you pour and alerts you when to stop As the ingredients reach the fill line, Perfect Dink alerts you to move on to the next ingredient.Perfect Drink compensates for over-pouring by re-adjusting the amount of the other ingredients automatically to fix your drink. If you didn't have time to stock the bar, just let Perfect Drink know what you've got on hand. It will generate a list of drinks you can make-and show you how. It's like having an expert bartender right in your kitchen.
