If, as one of the innumerable brewers of Europe, you responded to the challenge of Pilsen and to the opportunity of pure strains of yeast, you also found yourself looking at how to continue to produce your fine traditional malt beer for those customers who had not jumped on the Pilsner bandwagon.
The great tradition of brewing beers truly underwent a revolution between 1800 and 1900. The lack of a scientific analytical standard back then prevents full definition of the changes.
The opportunity to engage in more dependable brewing and thus produce more consistent beers could not be ignored - so dark lagers soon emerged, replacing many "old" or alt beers.
Using a blend of the range of consistently coloured malts then becoming available, brewers around 1900 constructed recipes and beers that remain superb to this day.
The distinct focussed maltiness of this fine micro dark lager is key to it's enjoyment; supported by the depth imparted by fine hops.
