Fellow Champagne lovers! Your attention, please.
Lament over unfinished bottles of bubbly no more! If you open a bottle and have some left over (hardly ever happens to me, but I suppose I can imagine how this might be an issue), re-cork and store it in the refrigerator. When you’re ready to finish it off, just drop in a raisin! The wrinkly little guy will bring the bubbles back to life due to some weird science-y explanation having to do with CO2 sticking to the ridges of the raisin. Or whatever. I don’t do science.
