Founded in 1843, Cook is one of the world's top champagne houses, and is part of the LVMH luxury group together with well-known wine brands such as Moët & Chandor, Veuve Clicquot and Dijin. Often described by aficionados as the "Rolls of Champagne", the scarce and high-quality Cook produces an average of only 450,000 bottles of champagne per year, only 1/100th of the annual production of Moët & Chandon, and is highly sought after by high-end collectors and drinkers – in the Champagne 50 Index compiled by the London International Wine Exchange, many of Cook's vintages are among them, and they are the most sought-after products in the secondary wine market.
 
Cook has created a complex wine storage system like a library, which stores more than 100 kinds of wines and nearly 10,000 bottles of wine harvested in the past, divided into villages, gardens and plots, which are the most valuable assets of Château Cook and are used to blend the main wine, Grande Cuvée. In addition to the abundant base wine resources, the stable level of winemaking is also the cornerstone of Cook's reputation, and Cook's chief cellar master has been a member of the family for more than 100 years, and now he is in his sixth generation.
 
For Champagne houses, Prestige Cuvée is the rarest and most expensive of the house's products, such as Dom Pérignon at Moët & Chandor, Cirtag Champagne from Louis Roederer and Belle Epoch at Perrier-Jouët. The exception is Cook, who is considered by many to be a top cuvée for all of its champagnes, even the Grande Cuvée, a non-vintage champagne. As the main product of Cook, Grande Cuvée is a demonstration of the exquisite blending level and style coherence of the winery, it has no concept of grape proportion, it combines dozens of aged wines, matures for more than 6 years, and has received a high score of about 95 points on wine critics, wine advocates and other wine review websites, which is higher than the top champagnes of many competitors.
 
In 1971, the fifth generation of the Cook family bought a small plot of land with an area of only 1.84 hectares in the famous Grand Cru village of Mesnil-sur-Oger in Champagne, and after the transaction was completed, Cook learned that vines had been planted as early as 1698, with a history of more than 200 years, and an excellent microclimate, which was ideal for growing Chardonnay. So, in order to showcase the terroir of this plot, Cook has launched the Champagne's first single-plot, single-vintage, single-varietal champagne – Krug Clos du Mesnil, which is widely regarded as one of the finest Chardonnay champagnes to date.
 
In order to replicate the classic of Krug Clos du Mesnil, the sixth generation of the Cook family bought a small plot of 0.68 hectares in the equally well-known Pinot Noir Grand Cru village of Ambonnay and made the vintage Clos d'Ambonnay, the first vintage of which was released in 1995 and released in 2007.
 
In addition to the above three, Cook has also launched rosé champagne, vintage champagne and collectible collections. Since 2011, Cook has marked all champagne bottles produced with an ID, which can be used by drinkers to go to the official website to learn about the grape variety, aging time and other information of the product.
