EPC was founded in June 2019 by Édouard Roy, Jérôme Queige and Camille Jullien Gilardi and sees itself as a start-up among champagne houses. The name stands for "EPiCurien". According to Queige, it is the first non-patronymic name in Champagne. Édouard Roy comes from a winegrowing family, Queige brings thirty years of experience in selling champagne, and Gilardi the marketing. The headquarters are in Épernay.
The house owns no vineyards of its own. The grapes come from partnerships with growers and cooperatives. The back label of each cuvée states who made it and which terroirs it comes from. The dosage is low, and instead of the flute EPC recommends the Blida, a small traditional glass. The Brut Non Vintage is 50 per cent Meunier, 33 per cent Chardonnay and 17 per cent Pinot Noir. It is made in stainless steel with full malolactic fermentation. There are also terroir cuvées such as a Blanc de Blancs from Bethon in the Sézannais and a Blanc de Blancs Grand Cru with Chardonnay from Avize and Oger.
In June 2025 EPC took over the champagne company Charles Mignon in Épernay, which had been founded in 1995 by Laurence and Bruno Mignon. A new Brut cuvée is being made there, while the other cuvées continue to come from the partner growers. EPC is present in more than 50 countries.
