Can I batch cocktails in advance?

Most spirit-forward cocktails can be pre-batched and stored in the fridge. Combine all ingredients except carbonated mixers (add these when serving). Citrus juice should be added no more than 4-6 hours before serving for best flavour. Dairy-based cocktails should be made fresh.

How much ice do I need for batch cocktails?

Budget about 150g of ice per drink for serving, plus extra for chilling. For a party of 50 with 3 drinks each, you need about 22.5kg of ice just for cocktails. Buy bags of ice cubes — most supermarkets sell 2kg bags. Store in a cool box or freezer until needed.

What is the dilution factor?

When you shake or stir a cocktail with ice, it dilutes by about 20-25%. When batching, you can add water to pre-dilute (20% of glass volume), or serve over ice and let guests stir. Pre-diluted batches are more consistent and faster to serve.

How do I adjust strength and sweetness?

Use the advanced options to adjust. Increasing strength by 10% adds 10% more spirit. Increasing sweetness by 10% adds 10% more syrup/liqueur. Start conservative — you can always add more. Taste-test a single portion before committing to the full batch.

How We Calculate This

This calculator scales single-serving cocktail recipes to your desired batch size.

How it works

Ingredients = Per-serving amount x number of servings
Bottles = Total ml / bottle size (700ml spirits, 1000ml mixers)
Ice = 150g per serving
Garnish = Servings + 10% spare
Cost = Sum of (ingredient volume x cost per ml)

The dilution factor adds water to account for ice melt during mixing. Adjust to taste.
