Approved on 2026-08-24 as Reflux. The original compound label “Reflux and Rectification” was narrowed because the evidence directly supports reflux, while rectification is a related but not identical concept.
Definition
The return and redistillation of condensed vapor within a still, increasing repeated vapor-liquid contact and separation before product collection.
Scope
Use this tag when
- Still geometry, plates, lyne-arm angle, cooling, or condensate return changes internal redistillation.
- Evidence explains how increased or reduced reflux affects spirit separation and character.
Do not use this tag when
- “Rectification” refers broadly to progressive enrichment across a column without a specific reflux mechanism.
- The material merely identifies a pot or column still.
- The subject is selection of heads, hearts, tails, or retained product fractions.
Boundary examples
- Included: A still head causes more condensate to fall back and redistill.
- Excluded: A distiller changes the hearts cut after tasting the run.

Governance decision
No duplicate Reflux term exists. Renaming the Proposed record preserved all evidence and process/equipment relations without creating another page. Rectification was removed as an alias; create it separately only if later sources show a recurring, independently useful retrieval need.
