BJCP 5C
A very strong and rich lager. A bigger version of either a traditional bock or a helles bock.
Most versions are dark colored and may display the caramelizing and melanoidin effect 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 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). Any fruitiness is due to Munich and other specialty malts, not yeast-derived esters developed during fermentation.
