There’s a reason wine collectors seek out big bottles: wine ages better in large bottles. Why is that?

Wine matures upon contact with oxygen, which infiltrates the bottle over time. This is highly desirable, as a constant supply of small amounts of air make wine more aromatically complex and soften its tannins. But once ageing ends, oxidation occurs, turning the wine sour. We want to delay this for as long as possible. That’s where magnum bottles come into play. Although the content of a 1.5 litre bottle is much larger than that of the 0.75 litre size, the neck of the bottle isn’t. That means the wine comes into contact with much less air in the same amount of time.

Our tip: Allow magnum bottles to age for an extra five years.
