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).

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. Ozzy

my tea turned blue !!!
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) "Ozzy" please.answer@NG wrote in message 4.196...
