Scaled ingredients
Formula
Scaled ingredient = per-serving mL × servings
Water to add = (spirit mL + modifier mL, scaled) × dilution %
Total volume = all scaled ingredients + water
Worked example. 20 servings, spirit 60 mL + modifier 20 mL scaled = 1600 mL alcoholic base × 20% = 320 mL water.
Questions
Shaking or stirring with ice doesn't just chill a drink, it dilutes it — typically 20–25% of the final volume. Batch it without that water and a pre-mixed cocktail served over ice or up will taste too strong and unbalanced.
Shaking incorporates more ice melt and air than stirring in the same time, so shaken drinks pick up more dilution. Both are averages — adjust to taste.
Only the alcoholic base and modifier — the water stands in for the ice melt those spirits would have picked up when mixed to order.
