===Opening Champagne bottles===
To reduce the risk of spilling or spraying any Champagne, the bottle is opened by holding the cork and rotating the bottle at an angle in order to ease out the stopper. This method, as opposed to pulling the cork out, prevents the cork from flying out of the bottle at speed (the expanding gases are supersonic).<ref>{{cite journal |last1=Liger-Belair |first1=Gerard |last2=Cordier |first2=Daniel |last3=Georges |first3=Robert |title=Under-expanded supersonic CO2 freezing jets during champagne cork popping |journal=Science Advances |date=20 September 2019 |volume=5 |issue=9 |pages=eaav5528 |doi=10.1126/sciadv.aav5528 |pmid=31555725 |pmc=6754238 |bibcode=2019SciA....5.5528L |doi-access=free }}</ref> Also, holding the bottle at an angle allows air in and helps prevent the champagne from geysering out of the bottle.

A [[sabre]] can be used to open a Champagne bottle with great ceremony. This technique is called ''{{lang|fr|[[sabrage]]}}'' (the term is also used for simply breaking the head of the bottle).<ref>{{cite web|url=https://expensivechampagne.org/how-to-open-a-champagne|title=How to Open Champagne Bottles|date=18 March 2021}}</ref>
