On The Rocks is a premium ready to drink cocktail line that has partnered with Beam Suntory to access true quality, premium spirits that set their products apart. While most RTDs these days use whatever the cheapest rotgut available is, OTR is all about premium booze, natural ingredients, and just enough creativity in the mix to set themselves apart. Perfect for picnics, airplanes, or anywhere on the go. OTR will put a bar quality drink in the palm of your hand in no time. Just pour over ice. The Cosmo is made with Effen Vodka for exceptional smoothness. Not too sweet and not too tart with just a hint of elderberry.
