Step 4: Insert the Corkscrew Into the Cork
Hold the bottle firmly with one hand and use the other to place the tip of the
corkscrew against the center of the cork. Slowly twist the corkscrew while
applying downward pressure to get it started into the cork. Continue twisting
the corkscrew into the cork being careful to keep it travelling down the center
and not towards the sides of the bottle. If you are to push the corkscrew too
far towards the side of the bottle, you may break the cork off. Continue
twisting the corkscrew into the cork until approximately ONE (1) twist
remains. The reason for leaving one twist of the corkscrew out of the cork is
in an effort to not push the metal entirely through the cork. Doing so will
push cork residue into the wine and contaminate it.
