How to make it
Stir the measured ingredients over ice until cold, then strain into a chilled glass.
Glass: Cocktail glass. Ice: None in serving glass. Garnish: Lemon twist.
Flavor & balance
- Boozy (Spirit-Forward) (dominant): Little nonalcoholic lengthening leaves the spirit or fortified ingredients prominent after chilling and dilution.
- Sweet (supporting): Sweeteners, fruit or sweetened modifiers round the attack and add weight; product sugar varies.
- Bitter (supporting): Cocktail bitters or coffee contribute a bitter accent; a small dose need not dominate.
- 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: premix with dilution trial.
- Measure and label the chosen product specification; chill appropriate glassware.
Finish chilling, dilution and garnish at service. Trial the actual serving method before approving a batch. Workload is an editorial assessment; no labor timing or storage validation is claimed.
