The pH of tea varies widely depending on the strength of the tea, and the type of tea used. Some green teas, such as chun mee, which have a sour flavor, are naturally slightly more acidic. The more strongly you brew tea (meaning, the more leaf used per amount of water, and the longer the steeping time), the more acidic the tea will be, and thus, the lower the pH will be. There are many sources that state the pH of ordinary black tea is normally from 6.0 - 6.6, but one scientific study measured it as low as 4.9. Even this lower figure is still within the normal range of mild food and drink. Soft drinks, by comparison, have a much lower pH. For comparison, pure lemon juice has a pH of around 2. The pH of tea is high enough that it is not a matter of health concern for anyone.
