From the brewery:

Unique barley malt from southern Germany, spring-fresh brewing water and the famous aromatic hops from Tettnang and Hallertau characterize the full-bodied taste of our Märzen Export. The higher original gravity and the mild hopping ensure the distinctive malty note.

"With every sip, the bitterness comes through better. The finish includes biscuit notes, fresh bread crust, from which the pleasant hop bitterness flashes, and a few herbal notes."
