The term Radler was invented by the great munich gastronomer Franz Xaver Kugler when somewhen in September 1922 aproximately 13.000 cyclists visited his tavern. On this particular day his beer started to run out, so he mixed the remaining beer with lemonade and pretended he created the Radler especially for the cyclists so that they could drive home without the risk of falling off their bicycle. During the summer months, radler is still very popular in Bavaria.
