Ummm, because of the bubbles, the dissolved CO2 and acid?
Nothing wrong with decanting Champagne if you prefer the effects of oxygenation, but the effects on the mousse and the acid are pretty obviously different than decanting still wines.
I’ll give it a shot, never even considered doing a decant. I will limit the decant to a younger champagne though and continue slow o with my older ones.
I agree. There’s a plus and a minus, unlike a still wine where there’s less/no minus. In the case of champagne, I feel like when I’ve tried a decanter the first glass can be good after a short decant, but if the rest isn’t consumed for 20 minutes I’ve had it degrade. I wouldn’t decant anything but an infant. If I think something will be tight I typically chill it a tad extra then pour the glasses and let them sit for a five minutes. That doesn’t allow for a dramatic change but it works for me, and the balance then has the additional time with increased head space.
To each their own, but there’s a reason that they bother to carbonate (which you’re paying for), and there’s a reason the great producers don’ t even turn out great chardonnays. There might be a few but they sure aren’t prolific. I remember having a good still wine over a dinner at one of the chateau but I don’t know that it is a release.
There’s some beneficial science behind the bubbles. They definitely change the sensation and delivery of the volatiles, though that doesn’t mean that you/some aren’t fine without the effects. There’s a Frecnh scientist named Ligier-Belaire (or thereabouts) that has some cool studies and writings on champagne.
