A drink mixer is a device that blends and mixes various ingredients to create delicious drinks. But if you're tired of using the same old term, consider these synonyms to add variety to your vocabulary. A cocktail shaker is ideal for shaking and mixing cocktails, while a blender is perfect for making smoothies and milkshakes. A juicer can be employed for extracting juice from fruits and vegetables. A whisk can create a frothy and airy texture in your concoctions. A stirrer or swizzle stick is used to blend drinks that do not require powerful mixing. And of course, a bartender is the human equivalent of a drink mixer.
