Belgian Lambics are a unique style of beer originating from Belgium, known for their spontaneous fermentation process. Unlike most beers that use cultivated yeast, Lambics rely on wild yeasts and bacteria from the environment, giving them distinct flavors and aromas. They are often brewed with a mix of barley and wheat, and can be aged for several years. There are several subtypes of Lambics, including Gueuze, a blend of young and old Lambics that undergoes a second fermentation in the bottle, and Kriek, which is made by adding cherries. These beers are typically tart and complex, appealing to those who enjoy sour flavors.
