It's actually very simple to open a bottle of wine. The bottle with two arms (or wings) will help lever the cork out of the bottle. The important thing to be considered is not to break the cork.
Remove the top of the lead or foil capsule by cutting around the rim of the bottle with the sharp point of the corkscrew. The arms of the cork-screw will have to be raised for this step.
Stand the bottle on a flat, hard surface at mid-chest level or lower. Lower the arms of the corkscrew. Holding the corkscrew as vertically and straight as possible, place the sharp *** directly into the middle of the cork.
Securely grasp the top of the bottle and the lower *** of the corkscrew with one hand.
With the other hand, begin turning the handle of the corkscrew clock-wise, applying an even, constant downward pressure into the cork. As the corkscrew goes into the cork, its arms will begin to rise.
Apply more pressure if the corkscrew will not penetrate the cork.
Keep turning the handle until the arms of the corkscrew are completely raised and the screw is well into the cork.
With one hand on each arm of the corkscrew, press the arms down. This will lift the cork out of the bottle.
Wrap your hand around the base of the corkscrew and lift straight up.
Remove the foil, if necessary.
Twist the cork off the corkscrew.
Wipe the rim of the bottle with a clean, damp towel before serving, to remove any stray pieces of cork and, more important, any lead left by the foil.
