Soy milk is a plant-based alternative to dairy milk made from soybeans. In the context of alcohol and cocktails, soy milk can be used as a vegan-friendly ingredient to provide a creamy texture and a slightly nutty flavor to drinks. It is often used in vegan cocktails as a substitute for dairy cream or milk to cater to those with dietary restrictions or preferences. Soy milk can add richness and a smooth mouthfeel to cocktails without the use of animal products.
