How much caffiene in a cup of tea?

Answer 1

Earl Grey is a black tea flavored with bergamot oil. Bergamot is a small citrus fruit from the Mediterranean. The caffeine in Earl Grey tea will be the same as other black teas.

There has been debate on the caffeine ratio of green vs. black tea. Generally, black tea is considered to have a third more caffeine than green.

Answer 2

Earl Grey tea has a level of acidity similar to other black teas. Earl Grey uses a standard black tea, often a Ceylon black tea, as the base. The flavoring, bergamot oil, adds aroma but does not hugely effect the acidity.

Also, acidity is a function of concentration, so it is hard to give an exact estimate of acidity...because tea contains mildly acidic substances, the stronger the tea is, the more acidic it will be.

As a general rule, tea, including Earl Grey tea, is slightly more acidic than water, but significantly less acidic than coffee.
