Anyway, Ruby Splash. Ruby splash is a welcome change in this world of flavor blasted snacks and drinks. Modern beverages are all hyper flavored, and I'm terrified of every variation of a classic drink that I pick up, because eight times out of ten, the added flavor is overwhelming. This is not the case with Ruby Splash. The hint of grapefruit is just that: a hint. It's very faint, but it is just strong enough to change the experience and give you a unique Sierra Mist taste. It's pretty good.
