This is a situation which might seem like an insuperable problem.
If you don’t have a corkscrew, the easiest way to open the wine bottle is to use kitchen shears or strong tongs to cut through the metal foil in two places.
Use one hand to hold the neck of the wine bottle and another to twist it in opposite directions. The foil will come off and you can pour the contents into your glass.
However, you can use more creative methods to bypass this obstacle. For example, if the cork is only slightly stuck in the bottleneck, you could try using a sturdy pair of pliers.
You can also try hitting the bottleneck against a hard surface – the cork will probably slide out after a couple of blows.
So this is how to open a wine bottle without a corkscrew.
