Each major Champagne house is known for its style, i.e., the recurrent characteristics that can be found in its wines, and that the result from deliberate choices made during the production process.

This can include, for example, wider use of a particular grape variety (and from certain parcels), a specific level of dosage, a greater use of reserve wines, or some unique features in the production processes like barrel aging.

The house style is particularly evident in brut non-vintage champagne, which is produced to provide consumers with a similar wine, year after year.
