Acidity Of Tea (Especially Black Tea) and Herbal Teas - RateTea Report
RateTea reports on the level of acidity in tea, particularly black tea, and herbal teas. Although tea is mildly acidic, its level of acidity is well within the range of other mild foods and drinks and is completely safe. RateTea provides details.
However, a majority of websites which discuss the issue of the pH or level of acidity in tea, do not cite any reliable scientific sources or studies, and instead casually throw around pH figures without any way to verify the source and truthfulness of these figures.
RateTea, an online tea rating and reviewing community which also publishes informational articles on topics related to tea and health, has recently published a report on the acidity of tea. This report cites scientific studies of tea and herbal teas, and also studies which measure the pH levels of various common beverages.
Summary of findings:
RateTea's research found that tea is only mildly acidic, less so than coffee, and considerably less so than common fruit juices, soft drinks (sodas), sports drinks, and energy drinks. Although the acidity of these beverages is enough to be a matter of concern for tooth erosion, the acidity of most typically-brewed tea is much lower, making tea a safer alternative for people concerned with tooth decay and looking for low-acid drink substitutes.
Although true teas from the Camellia sinensis plant tend to be low in acidity, the same is not necessarily true of herbal teas. Hibiscus is one herbal tea which is particularly acidic.
