Ruby Rum Sunrise
About
The Ruby Rum Sunrise is a citrus-forward cocktail that leans into both flavor and visual appeal.
White rum forms a light, clean base that lets the other ingredients stand out without adding too much weight. Grapefruit juice brings a sharp, slightly bitter citrus edge, which gives the drink its character and keeps it from feeling overly sweet. Sour mix adds a touch of balance, softening the sharpness just enough to keep the drink approachable.
Grenadine is what transforms the drink. Beyond its gentle sweetness, it creates that signature layered “sunrise” effect, settling at the bottom and slowly blending upward. The result is a cocktail that shifts both in color and flavor as you drink it.
While its exact origin isn’t clearly documented, the Ruby Rum Sunrise follows the lineage of classic sunrise-style cocktails from the 1970s, where simple builds and visual layering defined the category.
The result is bright, slightly tart, lightly sweet, and visually striking. A drink that feels refreshing but still has structure.
Shaken or Stirred? Partially shaken, then layered. The base is shaken to combine and chill, while the grenadine is added at the end to create the layered effect.

Tasting Notes
The Barsys Edge
Layered drinks can easily lose their structure if the base isn’t balanced. Barsys keeps the foundation precise, so the visual and flavor both stay intact.
Sip Setting
This is a daytime drink. Best enjoyed in natural light, where the layered colors actually show up. Easy, refreshing, and meant for relaxed settings.
Garnish Game
A lemon wedge adds a fresh citrus aroma and keeps the garnish clean. Avoid overloading it - the visual layering is already doing the work.
