Wine ullage: make fill-level records you can compare

Tue, 20 Oct 2026 00:00:00 +0000

Record ullage with a dated photograph, a clear reference point and the bottle’s identity. Compare like bottle shapes, and keep the visible observation separate from a judgement about quality. A low fill can be a reason to ask questions; a high fill cannot certify authenticity, storage or how the wine will taste.

Ullage describes the space left above the wine, commonly discussed through the fill level. The wine glossary gives the short definition. For a buyer or collector, the practical task is to document the particular bottle well enough that another person can understand the observation.
