How to make it

Pour ginger beer over ice, then float the specified Goslings rum on top.

Glass: Highball. Ice: Cubes. Garnish: a lime wedge or slice.

Flavor & balance

  • Spicy (Heat) (supporting): Ginger or pepper seasoning supplies heat distinct from ethanol warmth.
  • Earthy / Herbal (supporting): Botanicals, fresh herbs or the base spirit give aromatic plant character; this is not a basic taste.

Assess sweetness, bitterness and tactile drying separately. These flavor expectations are based on recipe structure, not measured tasting scores. Actual products, ice and dilution will change the result.

Preparation & batching

Service complexity: low. Batchability: spirit components only.

  • Measure and label the chosen product specification; chill appropriate glassware.

Add carbonated ingredients at service; do not shake or store the finished fizzy drink as a still batch. Workload is an editorial assessment; no labor timing or storage validation is claimed.
