Being Canadian I am fairly resourceful, in spite of this I can’t wrestle a bear, start a fire by rubbing sticks together or read a compass, but I can get a cork out of a wine bottle without a corkscrew. I’m sure this doesn’t surprise any of you. So, if you ever find yourself in this situation try one of these.
2.) Remove the plastic bit that covers the cork, wrap the end of the bottle in a towel and bang it ‘gently’ against a tree, fence or something similar (avoid concrete for obvious reasons). It will gradually make its way out. When enough is protruding grab the cork with your fingers and gently twist and pull.
3.) Push the cork into the bottle. You can use just about any kitchen utensil. My favourites are butter knives or the handle of a wooden spoon. Be careful as some may spray out but this is better than no wine at all.
4.) If you’re a bit of a DIYer you can drive a screw into the top of it and use a pair of pliers to pull it out.
