Supported style connections
Where the current style foundation connects
Absence from this list does not mean an ingredient cannot be used. Presence means BEU currently has source support for the relationship.
No BEU005 style relationship is asserted for this foundation node yet.

Why this ingredient connects
4 relevant foundation edges.
derived from
Pilsner Malt
Malting transforms barley grain into brewing malt; Pilsner is represented as a processed malt class.

Vienna Malt
Processed malt identity anchored to barley grain.

Roasted Barley
Irish stout context supports roasted barley as a processed grain ingredient.
Beer Atlas
Where this ingredient connects geographically
Origin place and brewing-tradition context are explicit. The absence of a place is not inferred as a global exclusion.
No BEU010 Atlas relationship is asserted for this ingredient yet.
Time Cellar
Historical anchors for this ingredient identity
These links contextualize documented use or historical evidence; they do not claim the ingredient was universally used from that point onward.
c. 13,700–11,700 cal BP; brewing interpretation around c. 13,000 BP
Raqefet Cave cereal-fermentation evidence
This records an archaeological interpretation of fermented cereal evidence. BEU does not convert it into an uncontested “invention of beer” date or a global first-ever claim.
ca. 1981–1975 BCE
Meketre brewery model depicts brewing work
The date belongs to the model and its archaeological context. The model is evidence of brewing representation and practice, not an origin date for Egyptian beer.
23 April 1516
Bavarian beer provision issued at Ingolstadt
BEU treats this as a specific Bavarian legal event, not as the invention of beer purity, a timeless recipe, or a rule that applied universally across all German territories and eras.
