Drinking is a sociable activity so bartending routinely involves making more than one drink at the same time. Fundamental as it is, the topic has received scant attention throughout the history of cocktail until now. Roundbuilding explores a wide array of bartending techniques, but specifically it considers how they combine when mixing rounds of drinks. This is the reality of professional bartending, and it deserves attention in its own right. If you’re looking for a book to beautify your coffee table, this may not be for you, but if you’re looking to better understand your methods, improve the quality of your drinks, or simply make your work-life easier, you’re in the right place. The book is the result of Daniel and Kevin’s four decades of combined bartending experience, from the Match Bar Group in the early 2000s to Satan’s Whiskers in the present day. That’s a lot of trial and error – and a lot of things they wish they’d known sooner – now available in one comprehensive guide.
