BEU006 canonical ingredient identity; not a commercial SKU or recipe mandate.
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.
Graph edges
Why this ingredient connects
2 relevant foundation edges.
affected by process
Ale Fermentation
S. cerevisiae is a biological actor in many ale fermentations; organism identity remains separate from the process.
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.

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.
1876 CE
Pasteur publishes Études sur la bière
The event records publication and its beer-science context. It does not claim Pasteur discovered fermentation or single-handedly created modern brewing science.

Homebrew Systems Thinking — No Recipe Required
Trace a homebrew-scale conceptual flow across ingredients, brewing stages, fermentation, conditioning, packaging, and quality context without prescribing a recipe.

brewing process
Ale Fermentation
A biological fermentation process in which brewing yeast metabolizes wort constituents and forms ethanol, carbon dioxide, and many flavor-active metabolites.

Saccharomyces cerevisiae — affected by process → Ale Fermentation.
Process influence is contextual; this relation does not prescribe an operating parameter or outcome. S. cerevisiae is a biological actor in many ale fermentations; organism identity remains separate from the process.

historical event
Pasteur publishes Études sur la bière
Louis Pasteur published Études sur la bière in 1876, applying microbiological ideas to beer fermentation, spoilage, and brewery practice.

Historical context only; this does not by itself prove invention, descent, causation, or exclusivity. Pasteur’s beer fermentation work is historically connected to yeast biology; BEU does not imply his 1876 taxonomy matched modern species concepts.

Weizen Brewing Yeast Culture
A brewing-use culture identity for phenolic German wheat-beer yeast, distinct from the S. cerevisiae species as a whole.
