Erdinger Alkoholfrei is an alcohol-free wheat beer from Bavaria, brewed with top-fermenting yeast in line with the Bavarian Purity Law. Since 2015, the brand has positioned it as a post-activity drink, and its isotonic profile makes that fit: isotonic means it matches the natural concentration of the body's fluids, supporting rehydration after exercise. The beer also contains vitamins B9 (folic acid) and B12. The malt character is aromatic, with a subtle hop presence and a brioche quality.
