Distinguishing between fake and real 2009 Menghai Dayi 7572 901 Ripe Tea

February 4, 2010

Recently I had the experience of acquiring 42 pieces of fake 2009 Menghai Dayi 7572 901 ripe tea. The counterfeiters are getting better year after year, and have become so proficient that I believe some market participants will disagree that the photos below show a fake Dayi product.

1. There is no dapiao 大票.

The big piece of paper telling you the manufacturer, name of the tea, often year, and other vital information of the tea in question that usually comes with a jian of tea. It is missing!

2. The hologram label on the tong

Take a look at the outer label. The vertical hologram

strip does not disappear completely. It has also been placed rather haphazardly and not completely pressed against the paper.

3. The paper quality and ink quality

This is where it gets interesting. The fake product actually looks better than the real product.

Real product on the left. Fake product on the right. The fake is made of thicker paper and the brown and blue ink colours are darker.

Just look at the numbers on the blue ink colour logo on the right - the blue serial numbers are too deep and thick to be real.

4. The way the wrapper is wrapped

Here is another tell-tale sign.

The real product is on the left - note how the wrapper is wrapped with the label over the brown words.

The fake product on the right - the wrapper is wrapped such that most of the brown words are obscured.

5. The wrapper label

(a) Note how the fake wrapper label is haphazardly affixed on the wrapper. It is not completely pressed on the paper. It was probably affixed manually rather than by machine.

(b) Note that the vertical hologram stripe is different on the fake and the real. The fake stripe does not completely disappear away when it goes under.

(c) Note that the real hologram stripe has the "dayi" words on it and is more shiny.

(d) Note that the real wrapper label has three colours - yellow, orange and dark orange (almost vermillion). The fake wrapper label only has two colours - yellow and orange. This is hard to tell from the photos but it is very apparent when you see it in person. This is the most obvious sign of a fake.

(e) The texture of the real wrapper label is thicker and coarser than the fake wrapper label.



6. The neifei 內飛

The neifei in the fake is completely deliberately obscured by the tea leaves, as though the counterfeiter has something to hide.

The neifei in the real cake is only partially obscured.


The neifei in the real cake has

(a) square corners

(b) distinct orange, blue and red colours

(c) clear vertical hologram

(d) blue and red numbers on the left and right margins

(e) been properly affixed on the cake

The neifei in the fake cake has

(a) rounded corners (very important distinguishing trait)

(b) no clear vertical hologram

(c) no blue numbers on the left and right margins

(d) not been properly affixed on the cake (see bottom left of label is sticking out)

7. The visual quality of the tea leaves

The fake cake contains foreign objects, like twigs and unknown clump of white dirt.

The real cake only contains tea.



The fake puerh tea market is alive and thriving. I recently attended the 2009 Shenzhen tea expo and spotted many more Dayi fakes (apart from 7572). The only way for innocent consumers to avoid acquiring fakes is to buy from reliable known sources like Yunnan Sourcing or authentic Dayi dealers on Taobao. Here are some pictures I grabbed from Yunnan Sourcing - you can see that they sell genuine products. Please note however it would be cheaper to buy from authentic Dayi dealers on Taobao as Yunnan Sourcing marks up its prices (which they are entitled to do so).

Update (7 Feb 2010):

Question: A LJ reader, Yuri Pragin, asked me whether I obtained any replacement/reimbursement from the merchant?

Answer: I did not go back since:
(a) it was 110 miles away from home
(b) at no point did he state that the tea was genuine - I also did not ask the seller to confirm they were
(c) the receipt stated "Puerh tea" not "Dayi"
(d) it would not be safe for me to kick up a fuss in China especially as I travel alone
(e) I figured he was not an authorised Dayi dealer.

Here is an example of an authorised Dayi dealer in Guangzhou:

Here are examples of unauthorised Dayi dealers in Guangzhou:


I suppose the next question is why I did not buy tea from an authorised dealer. The reason is because I noticed that ADs always markup their tea at a higher price (between 10 to 50% more) and some insist on selling at the Recommended Retail Price. However I have learnt my lesson and now only purchase Dayi exclusively from ADs.
