Life In 19x19

I was in the store front of my favorite tea shop yesterday. When I got home, I realized that the shopping bag they they had given me had two gentlemen playing Go on the front! I'm curious as to what the writing on the bag says, but I have no Chinese language skills at all. Can someone post a translation for me?

Here is the front of the bag:


Here is a close-up of the writing on the upper right of the front:


And this writing is on the side of the bag:

I think it's something like "the most interesting beverage isn't booze; the immortals themselves esteem mere tea." but I'm sure a native speaker will be along to give you a better translation.

(or maybe it refers to where the immortals drank (a mountaintop, one presumes) rather than where they rank tea)

As a native speaker, I must admit I don't fully understand XD

I think jts's translation is right, though.

Also, the side is just asking you to use paper products for the environment.

品酒师 = sommelier; someone who has mastered the knowledge of and enjoyment of wine so much that he can recommend to others
品水师 is therefore probably a sommelier of water

Thus the translation of the shopping bag should be something like the following:
The meaning of mastering the knowledge and enjoyment of a liquid is not really referring to wine.
For the sages, only tea is the apex.

I don't think pinjiou there refers to the refinement of the waiter (as with pinde or pinxing) but to the fact that he helps you try different varieties of wine. I agree that pinshui is probably supposed to be super-category that encompasses both pinjiou and pincha.

I think there's no sense in trying too hard to decipher it. It's not particularly well-written, and I suspect probably just a company slogan. The first part might be a reference to "醉翁之意不在酒".

could i sneak in with a translation request of my own?

on a dizi flute i've bought few months ago is chinese text, said to be a poem. would you mind translating it for me?
