You're right that beer is typically based on grains. However, it may be common practice in many places around the globe that beer (also wine, juices and other drinks) are filtered using animal based ingredients such as gelatine in order to remove any unintended substances / remnants from the beverage (e.g. tiny apple pieces in a juice). The producers are not obliged to declare this on the packaging.
