Is it safe to open champagne bottle with cork screw?

No, it is not safe to open a champagne bottle with a regular corkscrew.

Here's why:

* Champagne bottles are pressurized. They have much higher pressure than wine bottles, and a regular corkscrew can't handle the force.

* The cork could break. This could send shards of cork flying towards you, causing injury.

* The bottle could shatter. The pressure could cause the bottle to explode, leading to serious injury.

Always use a champagne opener (also known as a "sabre" or "wine sabre") to open a champagne bottle safely. It's designed to handle the high pressure and to remove the cork cleanly without breaking it.
