Earl Grey is a black tea that is flavoured with oil from the rind of bergamot orange, a fruit mostly grown in Italy. Variations on the traditional blend include Lady Grey (a blend of Earl Grey with blue cornflower blossoms), Russian Earl Grey (Earl Grey with pieces of citrus peel) and Red Earl Grey (rooibos and bergamot).

Grey was respected but rarely loved. His achievements were few, but they were significant…. In character he was a man of contradictions, headstrong but easily discouraged by failure, imperious but indecisive, cautious and introspective.
