The Helix.

My previous post, Four-Buck Chuck, made mention of an "innovative closure."  Meet the Helix.  The brainchild of Amorim (one of the planet's biggest cork producers) and O-I (a rather large bottle manufacturer), the Helix closure combines a grooved cork with a correspondingly threaded bottleneck.  Bronco Wine Company was an early adopter of the Helix cork stopper for several of their value-priced wines.
With the Helix there is no need to look around for a corkscrew, there is also no need to feel like one is slumming it by buying a screw cap closed wine.  Additionally, in some small way, the Helix manages to preserve the romance of opening a bottle of wine and the pleasant pop that a real cork delivers when it is coaxed out of a bottle.
I for one found the Helix to be a little hard to twist in and out (despite multiple printed exhortations suggesting otherwise), but I did find it rather interesting.  And innovative.
