There is a myriad of devices that assist in the removal of the cork from a bottle of wine.
These are listed in order of how easy it is to remove the cork from the bottle.
The corkscrew that removes the cork with the minimum of effort is the CorkPops. This opener contains a gas cartridge that literally pops the cork out like a bottle of Champagne.
The Houdini.
The double lever corkscrew (Rialto) uses two levers to cut the force necessary to extract a cork in half.
The least expensive corkscrew that we sell is the Softouch which uses a single lever.
There are less expensive corkscrews available, but they usually do not have the comfortable handle that the Softouch has.
