A standard pour of whiskey typically ranges from 1.5 ounces to 2 ounces, depending on the establishment and local customs. This measurement is often referred to as a “single” and is the basis for most cocktail recipes. It’s important to note that some bars may offer different pour sizes, or “doubles,” which are typically twice the size of a single.
Understanding standard serving sizes is crucial for responsible alcohol consumption, accurate recipe following, and consistent cocktail creation. Historically, standardized measures were less common, leading to variations in drink strength and potentially contributing to overconsumption. Modern bar practices emphasize consistent pours, allowing patrons to better manage their intake and bartenders to maintain predictable drink quality. This consistency also ensures that classic cocktails maintain their intended flavor profiles.
