Fred I do not mean to be difficult but:
Saaz were grown in Bohemia, modern day Czechoslovakia, and have a spicy nose and a spicy flavor.
Czechoslovakia existed from 1918 to 1993.
In 1993 It split into two republic Czech Republic and Slovak Republic.
Bohemian Pils must exhibit the spicy character of the Saaz hops to be in style.
Not necessarally. There are Czech Pilsner brewed (in Czech republic) with 100% Magnum.
The water was extremely soft.
May be in Pilsen.
Bohemian pilsner is brewed in lager geographical area then just city of Plzen / Pilzen.
Water softness vary from soft to moderate.
Pilsner Urquall is a fine example of the style but there is more to Bohemian Pilsner then just Pilsner Urquell.
If you ever travel to Czech republic try to find small independent breweries.
You will discover wide array of beers that are Bohemian Pilsners and might not fit into BJCP style guidelines.
And now carry on.
