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

Go ahead and drink it, but I suggest you try it when sober. Toci

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)
