Quite often people do not realise why they like a certain champagne brand. Some houses focus on the pinot noir grape in their champagnes which provides big, round and powerful cuvées and some houses focus on chardonnay which provides more mineral drive, citrus and elegance. If you prefer the latter, then perhaps consider a bottle of Laurent-Perrier as your 'go-to' entertaining wine.
This maison has a serious history but over the last 100 years has had a long line of influential women at its helm (Mathilde Emilie Perrier in 1812 and later in 1938 Marie-Louise Lanson de Nonancourt), and we cannot help but think that this has influenced the style – graceful, elegant and sophisticated. Of the larger maisons in champagne this is more subtle and understated in its profile. This may be to your preference and it is an affordable champagne label.
