Pre-Prohibition Lager
2015 edition of the BJCP Style Guidelines
Vital Statistics
Description
Aroma: Low to medium grainy, corn-like or sweet maltiness may be evident (although rice-based beers are more neutral). Medium to moderately high hop aroma, with a range of character from rustic to floral to herbal/spicy; a fruity or citrusy modern hop character is inappropriate. Clean lager character. Low DMS is acceptable. May show some yeast character, as with modern American lagers; allow for a range of subtle supporting yeast notes.
Appearance: Yellow to deep gold color. Substantial, long lasting white head. Bright clarity.
Flavor: Medium to medium-high maltiness with a grainy flavor, and optionally a corn-like roundness and impression of sweetness. Substantial hop bitterness stands up to the malt and lingers through the dry finish. All malt and rice-based versions are often crisper, drier, and generally lack corn-like flavors. Medium to high hop flavor, with a rustic, floral, or herbal/spicy character. Medium to high hop bitterness, which should neither be overly coarse nor have a harsh aftertaste. Allow for a range of lager yeast character, as with modern American lagers, but generally fairly neutral.
Mouthfeel: Medium body with a moderately rich, creamy mouthfeel. Smooth and well-lagered. Medium to high carbonation levels.
Impression: A clean, refreshing, but bitter pale lager, often showcasing a grainy-sweet corn flavor. All malt or rice-based versions have a crisper, more neutral character. The higher bitterness level is the largest differentiator between this style and most modern mass-market pale lagers, but the more robust flavor profile also sets it apart.
Comments: The classic American Pilsner was brewed both pre-Prohibition and post-Prohibition with some differences. OGs of 1.050–1.060 would have been appropriate for preProhibition beers while gravities dropped to 1.044–1.048 after Prohibition. Corresponding IBUs dropped from a preProhibition level of 30–40 to 25–30 after Prohibition
Ingredients: Six-row barley with 20% to 30% flaked maize (corn) or rice to dilute the excessive protein levels; modern versions may be all malt. Native American hops such as Clusters, traditional continental hops, or modern noble-type crosses are also appropriate. Modern American hops such as Cascade are inappropriate. Water with a high mineral content can lead to an unpleasant coarseness in flavor and harshness in aftertaste. A wide range of lager yeast character can be exhibited, although modern versions tend to be fairly clean.
