Is On The Rocks Cosmopolitan Gluten Free?
OTR™ Cosmopolitan is not gluten-free. It is crafted with EFFEN® vodka, a spirit distilled from wheat. While the distillation process typically removes gluten proteins, the presence of wheat as a base ingredient means that the final product may not be entirely free from gluten traces. Therefore, individuals with celiac disease or severe gluten sensitivities should exercise caution. Additionally, OTR™ cocktails are produced in facilities that may not be certified gluten-free, introducing a potential risk of cross-contamination.
Given these factors, the On The Rocks Cosmopolitan cannot be confidently classified as gluten-free. For those strictly avoiding gluten, it's advisable to consult with a healthcare professional before consuming this cocktail.
What Percentage of Alcohol Is in a Cosmopolitan On The Rocks?
The On The Rocks Cosmopolitan contains an alcohol by volume (ABV) of 20%, which is equivalent to 40 proof. This makes it stronger than your average pre-mixed cocktail, delivering a well-balanced blend of flavor and potency. This ready-to-serve cocktail offers a sophisticated sip with just the right amount of kick, perfect for enjoying over ice at home or on the go.
How Many Servings Are in On The Rocks Cocktails?
Most Cosmopolitan On The Rocks cocktails come in a 375ml bottle, which typically contains about 2 to 3 standard servings, depending on how generously you pour. A standard serving size for a cocktail is generally considered to be 4 to 5 ounces. Whether you're hosting a small gathering or relaxing at home, a single bottle offers a premium cocktail experience without the need to mix or measure.
