Master The Art of Muddling Cocktails | Diageo Bar Academy

Diageo Bar Academy | A variety of muddlers

Muddling is a great technique to release flavour and aromas from your ingredients and it is a vital skill to know when creating some classic serves, such as a mojito or caipirinha. So, let’s take a look at how to ensure your ingredients are muddled to perfection.

What is a Muddler?

The integration of fresh ingredients to cocktails is made possible through a process called muddling. Using a muddler tool, ingredients can be pressed to extract juices and oils. These are added, with other ingredients, to complete a cocktail.

A well-stocked bar will usually have an assortment of muddlers which can be matched to different styles of ingredient for a variety of cocktails.

A classic muddler takes the form of a bar with a slightly flared, circular end. The very end of the bar is flattened, allowing the bartender to crush ingredients against the side of the glass, and the flared end can be used to grind ingredients in a glass.

To muddle drinks, you need to have the tools. Here’s what you need in order to perfect your muddling technique:


Wood, stainless steel or plastic, with or without teeth.

Mixing glass

A toughened glass strong enough to withstand the firm action required to crush tougher ingredients, such as fresh ginger. This glass can be a mixing glass but you can also use a Collins or rocks glass.
