Magnum refers to a large-format bottle containing 1.5 litres (double a standard 750ml bottle). Magnums offer several advantages: better aging due to slower oxidation (lower surface-area-to-volume ratio), improved colour and bouquet development, and distinctive presentation. Magnums are expensive and less widely produced than standard bottles. Collectors often seek magnums for important bottles, particularly Bordeaux and Burgundy. A magnum of '82 Bordeaux commands premium pricing over two standard bottles.
WHY IT MATTERS FOR COLLECTORS
Magnums age beautifully, developing superior character compared to standard bottles. Premium wines in magnum format are excellent investments and showcase bottles.
Tasting cues
- 1.5 L format — often ages more slowly and evenly than a 750 ml of the same wine.
- Service impact: theatre and fewer cork pulls for a table of six to eight.
- Not every wine is bottled in magnum; availability skews toward prestige and sparkling.
Examples
- Champagne and grower sparkling frequently offer magnums for celebrations.
- Classified Bordeaux and cult reds appear in magnum at higher premiums.
- Jeroboam and larger formats continue the same slow-ageing logic with more logistics.
Cellar actions
- Account for shelf height and weight — magnums need sturdy storage.
- Plan service: one magnum ≈ two standard bottles for pacing a meal.
- Prefer magnums for long holds when you already trust the wine in 750 ml.
