Mountaineer – Rum Citrus Ginger Highball with Black Pepper

A refreshing rum highball that leans bright, fizzy, and just a little unexpected. The Mountaineer blends citrus and ginger into a clean, outdoorsy drink with a subtle peppery edge that keeps things interesting without overcomplicating the build.

Background

The Mountaineer isn’t a historical classic but follows the long tradition of highballs—simple, spirit-forward drinks lengthened with carbonation. This style gained popularity in the early 20th century for its ease and refreshment, and this version adds a modern twist with layered citrus and a hint of spice.

What You’ll Need

Ingredients

• Rum – the smooth, slightly sweet base that anchors the drink
• Orange juice – adds body and soft citrus sweetness
• Lemon juice – sharpens the profile with clean acidity
• Ginger ale – brings effervescence and gentle spice
• Black pepper – adds a dry, aromatic finish

Substitutions:

• No ginger ale? Use ginger beer for a bolder, spicier kick
• No orange juice? Try pineapple juice for a more tropical angle
• No lemon? Lime juice works as a direct substitute

Equipment

• Collins glass
• Bar spoon
• Ice

Why This Highball Stands Out

Citrus with Lift, Not Weight

The combination of orange and lemon keeps the drink bright without becoming heavy or overly sweet, giving it a clean, refreshing finish.

A Subtle Spice Edge

The ginger ale and black pepper work together to add complexity without turning the drink into a spice bomb—just enough to keep each sip interesting.

Substitutions & Variations

• Swap white rum for aged rum to add depth and warmth
• Add a dash of bitters for extra structure
• Top with soda water and a splash of ginger syrup for a lighter version
• Garnish with mint for a fresh herbal layer

Helpful Tips

• Use fresh citrus juice for the cleanest flavor
• Fill the glass fully with ice to control dilution
• Pour the ginger ale slowly to preserve carbonation
• Add the pepper right before serving for maximum aroma
