Gueuze is a traditional Belgian beer that is a blend of young and old lambic beers. It undergoes a secondary fermentation in the bottle, which gives it a unique, effervescent quality. The result is a complex flavor profile that can include notes of fruit, funk, and tartness, making it a favorite among craft beer enthusiasts. Typically served in a flute or tulip glass, Gueuze is often enjoyed on its own or paired with food. It is a key part of Belgium's rich brewing heritage and is recognized for its distinctive sour taste, which sets it apart from other beer styles.
