How to Make a Classic Tom Collins

American Bartenders School on Instagram: "The Collins family includes several different drinks, with the most common being four main variations based on the type of alcohol used. These include the Tom Collins made with gin, the John Collins made with whiskey, the Vodka Collins, and the Rum Collins. While bartenders can create many custom versions, these four are generally recognized as the main Collins drinks because they follow the same basic recipe but use different spirits."
