When exactly did Pilsner-style pale lagers conquer central Europe, replacing the earlier styles that had existed here for centuries? Where did they get their foothold, when, and for what reasons? I don’t have the answers yet, but I’ve recently been working in the archives of the Czech National Library, reading a bit more about eighteenth- and nineteenth-century brewing in the region. And just yesterday I found an interesting quote in Carl Balling’s Die Gährungschemie (3rd ed., 1865), regarding beers made from oats.
