How to Batch Old Fashioned Cocktail for a Crowd

The Old Fashioned cocktail lends itself to pre-batching and makes a great choice for winter parties and social gatherings.

Batch Old Fashioned Cocktail

If you’re hosting a dinner party at home or planning a cocktail party, the Old Fashioned is one of the easiest drinks to batch, requiring a base spirit, simple syrup and bitters. Batching cocktails saves time, allowing you to mingle and for your guests to serve themselves. It’s delicious and warming on a chilly night and you can choose from a variety of dark spirits such as whisky, bourbon, rye whisky and rum.

When making an Old Fashioned, the drink is stirred with ice for chilling and dilution. Here, we’re adding water to the batched cocktail so that guests can just help themselves to a drink on the night. This method delivers consistency of flavour and saves the need for extra ice.

The following recipe uses one full 700ml bottle of dark spirit. You can learn how to make your own simple syrup. Here’s how to batch the old fashioned cocktail for a crowd.
