Sharing excellence


  • Classic good tasting 7542 recipe with a fair amount of old and big tree leaves in it
  • Excellent clean Taiwan natural storage
  • Full thick taste, present Qi

“Serious Formula”, also known as “Conscientious prescription” (commissioned by the Hong Kong Henry company to Menghai Tea Factory/DaYi) simply put, it’s much better than DaYi’s 7542 (which is very much the reference factory cake) of the period, and this is mostly due to its superior composition, with more big and old tree than DaYi’s.

The storage on this batch is great, the best I tried of various 7542s of the period, I’m happy to recommend this to anyone wishing to understand why (DaYi) 7542 is the reference recipe for puerh, to have a great factory cake to age for longer, or simply to enjoy now as it’s pretty thick and fun to drink.

With traditional processing, it delivers both classic old tea taste (without storage) and a corresponding calming Qi, at a very moderate price for what it is.

This is a good one to age to eventually get the same feeling of famous 80s-90s factory cakes and its price is steadily going up with time.

This tea was one of the two teas I brewed for week 4 of Brew Puerh like a Pro

~357grams cake.


7 grams, 25 grams, 1/4 slice, full cake, 1 tong + 1 cake

    The tea tastes nice but it felt bad for my body and mind. It was uncomfortable to drink and give me unfocused dizzy mind set. It’s not for me.

    To be honest, I find it a bit difficult to rate the tea. Firstly, because the sample was only enough for one session, and secondly, because I don’t belong to the ranks of those who grew up with famous factory teas in the Pu world. Nevertheless, I can understand the popularity of the 7542 recipe and I am only just beginning to dig deeper into it. For me, the tea is a good example of a cleanly aged 7542 with a very tasty mixture of old tea taste and the classic 7542 taste still shining through, I have to agree with Paolo here. Where I personally have to disagree is the calming qi of the tea, as I felt it had a lot of overstimulating power, at least in my usual way of brewing it. You definitely have to listen to this tea and take the necessary time, maybe even deviate a little from your usual metrics.

    Of course you won’t find here the complexity we have come to enjoy in (very good) newer cakes, but indeed this is pretty much a “better 7542”. Patience, clean storage, simplicity and purity, it’s great. Trying not to drink it all too fast 🙂

    This tea is very clean for its age. Personally I feel this tea more on the strong side with both its flavor and Qi. I feel it can be a little more intense than others I have had. Overall this is a great tea and I highly recommend it for the price.
