What is teaching?

is a small kitchen gadget designed to remove the cork from the wine bottle. The most basic model of teaching consists of a metal tip in the shape of an open spiral (helix) connected to a wooden handle. The user concentrates the Helix point on the top of the cork and vomits until the wire becomes safely rooted into the cork body. Securing the bottle with one hand the user then pulls the handle until the cork is released. The cork can then be removed from the teaching and examined or discarded. For this reason, many mechanical improvements of traditional corkscrew design have been made. Some provide a more lever effect for pulling cork, while others emphasize more torque during twisting. The worm (spiral -shaped surgery) is twisted into the cork as before, but the waiter uses the lever mounted on the side lever to lift the cork by one liquid movement. Another improvement leads to a corkscrew with a double lever event. Two "wings" are mechanically pulled up on the gear when the worm drill dabout the cork. The user puts the bottle on the table and presses down on both wings. The cork is pulled by a straight assembly of the central device.

An even newer ejector design called a "rabbit" uses both increased torque and vertical lever to pull on the cork. The winery began to replace bottles with a cork for investing in a complicated corkscrew system may not be necessary.

by using the corkscrew can prevent some of the most common risks to open the wine. The lower corridor with a fixed snail instead of an open spiral can dig too much from the cork, which could lead to the contamination of the bottle. Complete drilling through the soft center of the older bottle of wine can also lead to problems with pieces of cork and damage when pulling. Those who are uncomfortable with the use of a traditional corkscrew can find a double lever system or rabbit corkscrew as the best investment.
