The attention given to food has increased in recent decades due to consumers' interest in the possible therapeutic and nutritional properties of foods. Eating habits are associated with the composition of the individual's gastrointestinal microbiota, so changes in the intake of macronutrients and fiber can induce changes in bacterial diversity. A healthy microbiota pattern tends to be observed when an individual includes fermented foods. However, most fermented foods are dairy products. They cannot be consumed by specific population groups, such as people who are lactose intolerant, allergic to milk protein, or for lifestyle and diet reasons, such as vegans and vegetarians. From this fact, there is a need to offer consumers an alternative non-dairy fermented product, exploring new substances to supply dietary probiotics. In this context, water kefir, a symbiotic culture of lactic acid bacteria, acetic acid, and yeast, stands out as a viable and affordable option, providing benefits similar to dairy versions without allergenic components that are undesirable for specific groups. Given the above, the objective of this work is to conduct a literature review on vegan fermented drinks, providing an overview of the fermentation process and matrices used, as well as presenting the factors that impact their adequate development, in addition to encouraging a discussion about the vegan fermented drinks market, including the issue of promoting research and development of new products from non-traditional sources, such as water-soluble vegetable extracts made from quinoa, cashew nuts, pistachios, among others.
