Grower champagne comes from small, family-owned champagne houses that produce their champagnes from the same estate that owns the vineyards. While larger champagne houses may use grapes sourced from as many as 80 different vineyards, grower champagnes tend to be more terroir-focused, being sourced from a single, or closely located, vineyard around the same village. They can be identified by the initials RM on the label.
Every year is different so the common criticism of grower champagne is the variable quality from one year to another. Although that may be the case with some growers, some of them make consistently outstanding champagnes. On the other hand, some say that blending grapes from so many different vineyards from the same region by the large champagne houses, makes those champagnes ”underflavoured” and ”non-distinctive”.
