The difference between vintage and non-vintage champagne is that vintage champagne is made from grapes that were all grown in the same year, while non-vintage champagne is a blend of grapes from different years. Vintage champagne is usually aged longer than non-vintage and is often considered to be of higher quality. However, non-vintage champagne can also be delicious and consistent, as it reflects the signature style of the producer.

There is no definitive answer to which one is better, as it depends on your personal preference and the occasion. However, some general differences are that vintage champagne is more unique and expressive of a single year’s harvest, while non-vintage champagne is more consistent and reflective of a producer’s signature style. Vintage champagne is also more expensive and rare than non-vintage champagne, as it represents less than 5% of all production and is only made in exceptional years.  Non-vintage champagne, on the other hand, is more affordable and widely available, as it is a blend of grapes from different years. Vintage champagne also requires longer aging than non-vintage champagne, which means it may develop more complex and mature flavors over time.
