Cocktail tools are essential items used for mixing, serving, and garnishing drinks. Common tools include a shaker for blending ingredients, a jigger for measuring precise amounts of alcohol, and a muddler for crushing herbs or fruits. These tools help ensure that cocktails are made consistently and tastefully. Other important tools include a strainer to separate liquid from solids, a bar spoon for stirring, and a zester for adding citrus flavors. Having the right cocktail tools can enhance the drink-making experience and allow for creativity in crafting unique beverages.
