This smart glass Boston cocktail shaker has everything you need to get started when it comes to shaking up the classics. You don’t have to worry about conjuring up recipes for creative concoctions. They’re printed on the side of the Boston shaker glass. These easy-to-follow recipes even feature ‘mix-to-the-line’ markers, so all you have to do is pour in the alcohols and mixers to the line, and shake. Other than the recipes, though, this is a pro cocktail shaker, through-and-through – right down to its built-in julep strainer and drip-free stainless steel lid.
