Berliner weisse is a type of sour wheat beer that originated in Berlin, Germany. It is typically low in alcohol (3-5%) and has a tart, refreshing flavour. Berliner weisse is made with a high percentage of wheat malt, which gives it a cloudy appearance and a slightly hazy flavor. The beer is also fermented with a blend of yeast and bacteria, which gives it its characteristic tartness.
Berliner weisse is often served with a shot of fruit syrup, such as raspberry or woodruff. This helps to balance out the tartness of the beer and adds a touch of sweetness. Berliner weisse can also be enjoyed on its own, or used in cocktails.
