MM. de St. Marceaux and Co. have the honour of supplying the King of the Belgians, the President of the French Republic, and several German potentates, with an exceedingly delicate champagne known as the Royal St. Marceaux. The same wine is popular in Russia and other parts of Europe, just as the Dry Royal of the firm is much esteemed in the United States. The brand of the house most appreciated in this country is its Carte d’Or, a very dry wine which, in conjunction with the firm’s Extra Quality, secured the first place at a recent champagne competition in England. In the neighbourhood of the Pommery and de St. Marceaux establishments numerous other champagne manufacturers have their cellars formed from the abandoned quarries so numerous on this side of the city. Of some of these firms we have already spoken, but there remain to be mentioned Messrs. Kunklemann and Co., Ruinart père et fils, George Goulet, Jules Champion, Théophile Roederer, &c. The cellars of the three last-named are immediately outside the Porte Dieu-Lumière, near which is a house with a curious bas-relief on its face, the subject of which has been a source of much perplexity to local antiquaries.
