Specifically, they wanted to know if the original Charles, the 2nd Earl of Grey, who lived from 1764 to 1845, ever drank the tea that bears his name. If you are fan of history or tea, this is definitely worth reading. Dating as far back as 1824, they found a references to bergmot (the main ingredient in earl grey) used as flavoring for tea.
So, did Charles drink Earl Grey Tea? You will have to read the Oxford post to find out.
