We do not have a description for Hasen-Bräu Extra yet.
These two styles are closely related, the former hailing from Dortmund and the latter from Bavaria. Both are slightly strong (5.0-5.6%), malt-accented pale lagers. The cookie-like or bready maltiness should be very much in evidence in a traditional example. These beers are clean and easy to drink in quantity. Some Dortmunders made in Denmark and the Netherlands are stronger.
