The Vitamix Aer Disc Container is a versatile blender attachment designed to master culinary techniques such as whipping, muddling, foaming, and emulsifying. It acts as both a muddler and a cocktail shaker, extracting essential oils and juice while chilling drinks without crushing the ice. The container excels at producing consistently creamy emulsions, light culinary foams, and stiff whipped creams. It is made of BPA-free Eastman Tritan and is dishwasher-safe. The container is compatible with all full-size Vitamix blenders, except for space-saving models.
