I first read about these on Frederic Koeppel’s “Bigger than your head” website. Metrokane, a wine accessory company has a line called Rabbit. High-tech wine toys. Great stuff. But this one every wine lover (and wine salesperson) should have a dozen of these in their drawer (or wine bag). And at $2 apiece, they are a deal. And the best thing? They need no batteries, no recharging, and no fuss. Just put them in an opened bottle of wine and let ‘em go. Jostle the bottles (not recommended) and they won’t come out. No spill. No mess. Color coded. Low tech. Just in time for the weekend.
