Dave Arnold – författare

Dave Arnold’s philosophy is simple: if you think like a scientist, you can make better drinks. Liquid Intelligence takes readers behind the bar and into the lab, where Arnold tinkers with temperature, carbonation, sugar concentration and acidity in search of new ways to enhance classic cocktails, from bubble formation to the ideal sugar compound for a daiquiri. With innovative techniques—clarifying cloudy liquids using gelatins, chilling drinks with liquid nitrogen—and practical tips for making infused liquors and homemade bitters, Liquid Intelligence is for anyone eager to learn the hows and whys of a beautifully made drink.
