Comparisons
Reusable keg, single-use keg, bottle: each format has its uses. Enough to compare wine-by-the-glass formats, with no value judgment.
Comparison
Bottle or draught, point by point.
The same criteria, both formats, and what each changes at service — the figures published on this site, gathered.
| Criterion | 75 cl bottle | Draught keg |
|---|---|---|
| Storage after opening | A few days | Up to 120 days |
| Glasses equivalent | 6 glasses | 160 glasses (20 L keg) |
| Serving gesture | Uncork, pour, recork | Pour by the glass at the tap |
| Packaging | Single use — 19 kg of glass for 26 bottles | Returnable, reusable keg |
| Container lifespan | One service | Estimated at 10 years (5 rotations/keg/year) |
| Manufacturing | — | 100% French |
| End of life | Recyclable glass | Keg 100% recyclable; liner recovered as RDF |
Two rows carry the essentials: keeping time after opening — a few days for an opened bottle, up to 120 days for a keg — and the glass equivalence, 6 versus 160 for a 20 L keg. The rest of the table follows the same container logic: single-use packaging versus a deposit-based keg, estimated at 10 years of use and made in France.
