Quoth da Whysall (just over a year ago):
I either drink Earl Grey (or Lady Grey - has a citrus note instead of bergamot) tea.
1) Bergamot is citrus.
2) It's in Lady Grey too.

From WP - Bergamot orange: "Citrus bergamia, the bergamot orange (pronounced /ˈbɜːrɡəˌmɒt/), is a fragrant citrus fruit the size of an orange, with a green color similar to a lime." ... "An essence extracted from the aromatic skin of this sour fruit is used to flavour Earl Grey and Lady Grey teas..."

Hmm... The etymology section only suggests a Turkish pear, not the city of Bergamo, as I'd have thought. The Online Etymology Dictionary disagrees with WP, seems to endorse my idea.
