Anyone know of any statistics available about the risk of finding premox in e.g. Magnums in relation to normal bottles?
In other words: could it be less risky to buy white Beaune and Chablis in larger formats?
No statistics, but since premox has to be at least partially caused by cork variation, and many producers use better quality corks in their large format bottles, the incidence may be lower.
I have so little firsthand or even secondhand knowledge of large format white Burgs that I haven’t a clue. I’m not sure I can even remember reading of anyone drinking white Burgs out of magnums, though I guess it must happen some. I think the only white Burgs I remember even seeing in the store in magnums were Chablis, not any from the Cote de Beaune.
My personal guess – and it’s just a guess – is that white Burgs in the last 15 years or so are just made in a riper, more gently pressed, fruitier, less acidic style than they used to be, which is far better for early consumption, but which resists oxidation and decline less than the white Burgs from earlier times.
If my guess is correct, then it wouldn’t matter very much if the wines are in 375, 750 or 1.5. But that’s just based on my guess, and there are many different opinions and no strong consensus on what caused the spike of premox.
My BdM '02’s out of magnum have been fantastic…
Single bottles were mostly all poxed.
