As we all know, often the first thing we check on a compressed Pu-erh is the date on the back of its packaging – age equals the value and quality in many Pu-erh consumer’s mind. A date on the back was however not required until 2007 as part of the local government's attempt to regular the Pu-erh production industry. So how do you decide the age of a Pu-erh produced before 2007 with a blank back like the one in the image?
A production date was regarded as not essential for Pu-erh teas until 2007, mainly due to there is not an expiry date for Pu-erh teas – the more they are aged the better, and the traditional way of how they were produced – in the villages and families. During the recent decades, various methods have been used to ‘fake’ Pu-erh’s age for the purpose of fetching a high price on the market. There are various aspects associated with an aged Pu-erh, such as tea colour and texture etc, each one can be manipulated up to certain point. The multiple aspects and dynamic nature of Pu-erh teas make judging their actual age hard, not only for the beginners buy also for many experienced Pu-erh consumers.
To establish some standards, the local governments in the Yunnan Province introduced the 12 points of information, such as the production date, the manufacturer and location etc, to be printed on the back of a Pu-erh product (apart from Maocha) in 2007 to offer consumers some references.
For the products produced before 2007 with a blank back, one can only go back to the very basics of aged Pu-erh teas drawn from experiences: colour, aroma, taste, texture and aftertaste.
