To scale any drink recipe up or down, multiply each ingredient by the ratio of new servings to original servings. This keeps the balance identical.
New = Base × (Want ÷ Makes)
What the terms mean
| Symbol | Meaning |
|---|---|
| New | Scaled ingredient amount |
| Base | Original ingredient amount |
| Want | Servings you want |
| Makes | Servings the recipe makes |
Worked example
A punch recipe for 8 scaled to 20: each ingredient is multiplied by 20 ÷ 8 = 2.5. A 2-cup juice becomes 5 cups.
Scale everything together. Multiply every ingredient by the same factor, including ice and garnish. Scaling only some throws off the flavor balance.
FAQ
Can I scale a recipe up by any ratio and expect it to taste the same? Mostly yes for simple ratio-based recipes, but very large scale-ups can shift extraction slightly due to longer contact or mixing time, so it’s worth tasting and fine-tuning once you’ve scaled a recipe well beyond its original batch size.
