have been drinking a ?cooked pu-erh... chun ming tuo with blue lettering on the wrapper....
after brewing, and drinking, the leftover tea turns a blue colour after some hours...
when drunk, the stuff looks and tastes fine...
why ???? (should I continue to drink it ??)
thanks, Andrew
Since no one has responded with an intelligent answer, I'll hazard a guess...
Perhaps your water is basic (high pH) rather than acidic (low pH). I'm wondering whether this is the same reaction you see in cooked red/ purple cabbage, which can turn blue if the pH is too high (vinegar is often added to keep the red color).
Just a SWAG,
Alan

His water might be full of iron, makes blue black colors with tannins

The questions about PH could be answered by making the tea in distilled water, if it's worth the trouble. Me, I think I would apply the motto, "What you don't know may hurt you a whole lot" to the sitation, and throw the tuo out -- it's only 100g of tea. You don't know what's causing the blue tinge. Why should it only emerge after several hours if it's due to the lettering? Dunno, but I wouldn't mess with it.

hey, thanks for the replies... !!
yes, my water, unfiltered has a pH of 8... however, the water, once filtered, which is how I make the tea, has a pH of 7... so alkaline water wouldn't seem to be an issue..
iron I am not sure about... again, I use a filter, which may or may not affect iron levels... but sounds plausible.. (if this is the case, I need to worry about the water, not the tea !!)
Toci - it looks a bit blue sober or drunk !! - actually, probably looks more blue sober - drunk I wouldn't care..!! (it's a blue tinge, not a pure blue)
Cheers, thanks, Andrew
(drinking a riesling atm)
