This sounds interesting – might have to give it a try! Although – hey, wait – champagne is made from grapes…..so drop in a shriveled raisin that is also from a grape and poof??!!? Bubbly champagne? Must try! From Real Simple:
Raisin as Champagne Restorer
Drop a raisin into the open bottle a few minutes before pouring and any last gasps of carbon dioxide that are left in the wine will stick to the raisin’s ridged surface, then release again as tiny bubbles. A little more sparkle to lift your spirits.
