Historical Beer: Piwo Grodziskie

BJCP 27

Overall Impression
A low-gravity, highly-carbonated, light-bodied ale combining an oak-smoked flavor with a clean hop bitterness. Highly sessionable.
Comments

Pronounced in English as “pivo grow-JEES-kee-uh” (meaning: Grodzisk beer). Known as Grätzer (pronounced “GRATE-sir”) in German-speaking countries, and in some beer literature. Traditionally made using a multi-step mash, a long boil (~2 hours), and multiple strains of ale yeast. The beer is never filtered but Isinglass is used to clarify before bottle conditioning. Traditionally served in tall conical glassware to accommodate the vigorous foam stand.

History
Developed as a unique style centuries ago in the Polish city of Grodzisk (known as Grätz when ruled by Prussia and Germany). Its fame and popularity rapidly extended to other parts of the world in the late 19th and early 20th century. Regular commercial production declined after WWII and ceased altogether in the early-mid 1990s. This style description describes the traditional version during its period of greatest popularity.
Ingredients
Grain bill usually consists entirely of oak-smoked wheat malt. Oak-smoked wheat malt has a different (and less intense) smoke character than German beechwood-smoked barley malt; it has a drier, crisper, leaner quality – a bacon/ham smoke flavor is inappropriate. Saazer-type hops (Polish, Czech or German), moderate hardness sulfate water, and a relatively clean and attenuative continental ale yeast fermented at moderate ale temperatures are traditional. German hefeweizen yeast or other strains with a phenol or strong ester character are inappropriate.
