Hop Splash starts from water, not beer. Sierra Nevada carbon-filters their brewing water, then steeps real Citra and Amarillo hops long enough to pull out the aromatic oils without drawing bitterness. The CO2 used for carbonation comes from the brewery's own fermentation, which is a tidy piece of engineering if nothing else. What you get is sparkling water with a genuine hop character. The Citra and Amarillo lean tropical: mango, peach, grapefruit, lychee. No malt, no grain, no bitterness. Just clean carbonation carrying bright citrus-tropical hop aroma. It sits closer to sparkling water than to any kind of beer, which is worth knowing before you crack one open expecting otherwise. Zero calories, zero alcohol.
