How to open the five mountains of Mount Tai at 39 degrees?

Step 1, Step 1: First cut the unsealed bottle cap along the circular protruding part of the bottle mouth with a knife, and pay attention to changing hands. Don't turn the bottle. If it is old wine, there will be normal precipitation at the bottom of the bottle, and turning the bottle will make the precipitation float.

2, the tablecloth will remove the ash from the bottle mouth, or mold ash. It's normal to have a little mildew, and you can't say that the wine is broken.

3. Gently clamp the bayonet of the metal joint part of the cutter head on the protruding part of the bottle mouth, and firmly hold the joint between the cutter body and the bottle neck by hand, so that the joint can be firmly clamped with the protruding part of the bottle.

4. Pull up the handle hard, and the cork is slowly pulled out under the pull of the lever (two focal points, one is the clamping part between the metal head and the protrusion of the bottle body, and the other is the contact point between the spiral needle and the center of the cork).
