As an expert sommelier and brewer, I can confidently say that Cook's champagne, like other sparkling wines, won't go “bad” in the sense that it becomes unsafe or undrinkable. However, just like any other wine, it will age and its flavor profile will evolve over time.
Cooks champagne is known for its affordability and accessibility, making it a popular choice for celebrations and casual gatherings. It is a non-vintage sparkling wine, which means it is made from a blend of wines from different years. Non-vintage champagnes are generally meant to be consumed within a few years of purchase, as they are not designed for long-term aging.
Over time, the flavor characteristics of Cook's champagne may change. The vibrant fruit flavors and aromas that are present when the wine is young may mellow and become more subdued. This is a natural part of the aging process and can be a pleasant evolution for some wine drinkers.
However, it's important to note that aging can also have some negative effects on sparkling wine. One of the most significant changes that can occur is the loss of effervescence. The bubbles in champagne are a result of carbon dioxide gas that is trapped during the fermentation process. As the wine ages, the gas can gradually dissipate, leading to a loss of the characteristic fizziness that is so beloved in sparkling wines.
In my personal experience, I have come across bottles of Cook's champagne that have been stored for several years and have noticed a significant reduction in the level of carbonation. While the wine was still drinkable and enjoyable, it lacked the liveliness and effervescence that I typically associate with sparkling wines. This loss of bubbles can be disappointing for those who prefer their champagne to have a lively and celebratory character.
To summarize, Cook's champagne won't go bad in the traditional sense, but it will age and evolve over time. The flavors may change and the effervescence can diminish, resulting in a different drinking experience. If you prefer a champagne with vibrant bubbles, it's best to consume Cook's champagne within a few years of purchase.
