Maturation & Conditioning
Post-fermentation conditioning during which beer composition and sensory-active compounds can continue to change before final clarification or packaging.

- Boundary
- Represents post-primary-fermentation maturation/conditioning as a process layer; not a fixed temperature/time program.
Non-prescriptive by design
No fixed time/temperature program is asserted.
Pathway position
What tends to connect before and after
These are sourced representative pathway edges. Branching and brewery-specific variation remain possible.

Diacetyl
Diacetyl concentration can change during fermentation/maturation; no universal target or maturation program is asserted.
affected by process
Buttery
The buttery descriptor associated with diacetyl is process-sensitive and context-dependent.

Traditions that contextualize this process
Tradition inclusion is contextual, not a claim that a process belongs exclusively to one place or culture.
No BEU010 Atlas relationship is asserted for this process yet.

sensory descriptor
Buttery
A butter-like aroma/flavor descriptor often discussed in relation to diacetyl, while remaining perceptually and contextually distinct from the compound itself.

Buttery — affected by process → Maturation & Conditioning. This explanation is being viewed from the target side of the directed relationship.
Process influence is contextual; this relation does not prescribe an operating parameter or outcome. The buttery descriptor associated with diacetyl is process-sensitive and context-dependent.
