We do not have a description for Heidelberger Naturtrüb yet.
Three related, minor, lager styles most common in Franconia. Essentially, these are hoppier versions of a helles, served with natural carbonation and unfiltered - they are the lager worlds answer to real ale. Kellerbier will on average be hoppier than zwickelbier. There is also Landbier, which is more malt-accented, may be filtered, but is similarly lacking in carbonation. Gravity is standard, hop rates ranging from 22-40 IBUs, the colour from pale to reddish-amber and the palate should be balanced with a hop accent.
