Whenever there has been a perfect grape growing period and harvest, it is almost certain that the Champagne region will declare a vintage. So what does vintage actually mean, more so it's usage within Champagne production.
Vintage simply means that the wine inside of the bottle is of one single year over a mixture of blends from different years being used. When a Champagne is a vintage, it will be clearly mentioned on the bottle label and a year will be stated. Bottles without a year are likely to be a non-vintage (NV) Champagne. Many people think of the word vintage as it is more commonly used, a word to describe the period of origin of an item, usually of several years / decades past - Examples are vintage clothing or vintage cars.
On most occasions, every Champagne producer will declare certain exceptional years a vintage, though there can be differences of opinion and certain years will see some releasing vintages and others not. There is no set rule, neither requirement, that a Champagne house should declare a vintage. It can be regarded that every year is a vintage year and each is simply graded from 0 to 5 stars with the 5 stars being the exceptional ones. Over the recent years there have been quite a few 5 star vintages including: 2022, 2018, 2012, 2008, 2002.
