A strong, rich, and very malty German lager that can have both pale and dark variants. The darker versions have more richly-developed, deeper malt flavors, while the paler versions have slightly more hops and dryness.
Most versions are dark colored and may display the caramelizing and Maillard products of decoction mashing, but excellent pale versions also exist. The pale versions will not have the same richness and darker malt flavors of the dark versions, and may be a bit drier, hoppier and more bitter. While most traditional examples are in the lower end of the ranges cited, the style can be considered to have no upper limit for gravity, alcohol and bitterness (thus providing a home for very strong lagers).
