Racking is the process of transferring wine from one vessel to another, leaving the settled lees behind.
Why rack?
- Remove gross lees after primary fermentation to prevent off-flavours from autolysis
- Introduce controlled oxygen to soften tannins and stabilise colour
- Clarify the wine progressively
Timing
- First racking — 1–2 weeks after primary fermentation ends
- Second racking — after MLF is complete
- Subsequent rackings — every 3 months during ageing
💡 After racking, always check and adjust your free SO₂ level. Oxygen exposure during racking can reduce free SO₂ rapidly.
