pH Levels Of Green Tea VS Black Tea

So as we know both green and black tea are made from the leaves of the Camellia sinensis plant and the only difference between the two is that black tea is oxidized and green tea is not.

Yet! Black tea seems to be more acidic than green tea but why? this is because of the way black tea is processed to green tea. The oxidation method, which turns the leaves from green to a dark brown or black color and just by processing black tea in this way, makes it so different from green tea and as a result, can also make it more acidic.


So yes green tea is acidic but not by much compared to other teas, as mentioned above. Green tea is one of the healthiest teas and is high in antioxidants, however! this can be said for black tea, yes it may be more acidic than green tea but still comes with all the health benefits just like green tea.

Because green tea has a pH level of 7 which is considered a very low-level drinking high amounts of green tea in the day, it’s not going to cause any side effects, unless you’re drinking a very acidic tea like lemon.
