茶叶保质期100年？COSTA电商平台旗舰店已无相关产品

Core Viewpoint - A consumer reported that a product from COSTA, specifically an organic Pu-erh tea, has an unusually long shelf life of 100 years, raising questions about the validity of such claims and the product's quality assurance [1][4]. Group 1: Product Details - The packaging of the COSTA organic Pu-erh tea indicates a production date of October 1, 2025, and an expiration date of October 1, 2125, suggesting a 100-year shelf life [1]. - The customer service representative stated that the tea can be stored for a long time if kept in proper conditions, but did not provide details on how the expiration date was determined or if there were any certifications [1]. Group 2: Market Availability - As of January 9, searches on major e-commerce platforms like Tmall and JD did not reveal any listings for the Pu-erh tea, with customer service indicating that the product had been taken off the shelves [3]. - Tmall's customer service mentioned that the tea was likely removed recently, while JD's service indicated that it was automatically taken down due to lack of stock [3]. Group 3: Tea Characteristics - Pu-erh tea is categorized into raw (sheng) and ripe (shou) types, with ripe tea undergoing a fermentation process that makes it milder in flavor compared to raw tea [3]. - The best shelf life for Pu-erh tea is generally around 10 years, and the concept of "aging well" applies only within this timeframe; improper storage can shorten its optimal quality [4]. Group 4: Company Background - COSTA Coffee was founded in 1971 in London and was acquired by The Coca-Cola Company in 2019, which expanded its product line to include ready-to-drink coffee and tea beverages [4]. - There have been considerations regarding the potential sale of COSTA's global store operations by Coca-Cola, indicating strategic shifts within the company [4].
