Often dubbed as Vietnamese corn wine, rượu ngô is a unique spirit distilled from local corn varieties. The drink is traditionally produced by ethnic minorities such as Hmong and Dao people located in northern mountainous provinces.
The production starts with boiled corn kernels that are fermented with spring water and yeast, usually made with various herbs and plants. After fermentation, the mixture is distilled, and it can be left to age. The final profile of these drinks can vary, depending on the exact techniques, the choice of ingredients, and the type of yeast.
