Every so often, , we editors get together and make like it's 1999 with a box of champagne that we just happened to pick up at Costco. OK, so it hasn't happened yet (and probably never will, considering how far each of us lives from the other), but it doesn't hurt to imagine. In our optimistic minds, we would have finished off the entire case, and wake up the next morning refreshed and ready for a six-mile jog in Malibu. However, what's more likely to happen is that we'll end up finishing two and a third bottles, wake up the next morning at 2 pm with a hangover so bad that we puke all over our Bertoia diamond wool-covered chairs. But who cares? We have two-thirds of champagne leftover and that is NOT heading down the drain! Now, we've heard of that old wives' tale of sticking a silver spoon in the bottle (apparently, it doesn't work. In fact, it'll make your champagne go flatter faster), and we've tried this Concerto Wine Saver from Williams-Sonoma, but it still tastes a bit flat the next day. Anyone have any other tips or tricks to save our dwindling champagne stash?
