What Is Earl Grey Tea

What Earl Grey tea is, in summary: Black tea flavoured with bergamot oil, the history (and the myth behind the name), the Earl Grey family of variants, and how to brew it. A plain guide.

Last reviewed by the teas.co.uk team in May 2026.

Earl Grey is named after a Prime Minister who probably never tasted it. The tea is black tea flavoured with bergamot oil, a distinct citrus-floral aromatic from a small bitter orange grown almost exclusively in Calabria, Italy. The origin story is colourful and mostly fiction; the cup is genuine and globally beloved.

The Charles Grey story (and why it's probably wrong)

Charles Grey, 2nd Earl Grey, was British Prime Minister from 1830 to 1834. The tea bearing his name has a popular origin story: a Chinese mandarin gifted him the recipe in gratitude for a British diplomat saving the mandarin's son from drowning, and Earl Grey then asked a London tea merchant to recreate the blend.

This story is almost certainly fabricated:

Earl Grey never visited China.
Bergamot was already a known tea flavouring in early-19th-century London, well before his time as PM.
No surviving period correspondence supports the tale.
The Earl's family has acknowledged that the story is folklore.

What likely happened: bergamot-flavoured tea was a known commercial product, possibly used to mask poor-quality tea or to create a distinctive blend. The "Earl Grey" name was attached for marketing reasons (associating the tea with aristocratic respectability), and it stuck. Twinings has marketed Earl Grey since the 1830s, and that brand connection became foundational to the name's persistence. By all accounts Earl Grey himself played no actual role in the tea named for him.

What bergamot actually is

Bergamot (Citrus bergamia) is a small bitter citrus that grows almost exclusively in the Calabria region of southern Italy. The fruit itself is rarely eaten, it is too sour and bitter; what is used commercially is the oil from the peel.

Bergamot oil contains:

Limonene. The citrussy top note.
Linalool and linalyl acetate. Floral, slightly lavender-like notes.
Bergaptene. A photosensitising compound (more relevant in cosmetic use than in tea).

The combination of these compounds is what makes bergamot's aroma so distinctive, citrussy and floral at once, in a way no other citrus oil quite manages.

How Earl Grey is produced

Black tea is processed normally (withering, rolling, oxidation, drying).
Bergamot oil (sometimes diluted with a carrier oil) is sprayed onto the dried leaves.
The leaves are mixed and packaged.

Some brands use real Calabrian bergamot oil; cheaper brands use synthetic bergamot flavouring or low-quality extract. The difference shows in the cup: synthetic bergamot tastes perfumed and one-dimensional, while real bergamot oil is complex and integrated.

Why Earl Grey became iconic

Distinct flavour. Bergamot is unlike any other tea flavouring; once you know it, you recognise it instantly.
British association. Tea-with-the-Queen imagery, and Captain Picard ordering "Earl Grey, hot" on Star Trek. It sits at the intersection of British tradition and global recognisability.
Versatility. It drinks well black, with lemon, with milk, in cocktails, in baking, and as ice cream. Few teas have that range.
Twinings marketing. Decades of consistent brand-building made Earl Grey a Twinings hero product.

How to brew Earl Grey properly

1 bag (or 1 tsp loose leaf) per 200ml.
Water at a full rolling boil.
Steep 3-3½ minutes, not 4-5; the bergamot oil turns acrid past 4 minutes.
Drink it black with a slice of lemon (classic) or with a little milk (British), but not both, lemon curdles milk.
Sugar is optional and not really needed if it is brewed correctly.

Caffeine

40-50mg per 200ml cup, the standard British black tea range.

The bottom line on Earl Grey

A flavoured black tea defined by bergamot oil, originally Chinese-blended and now overwhelmingly Indian or Ceylon-based. The signature citrus-floral character has made it the most-recognised "polite tea" in the British cupboard. Worth keeping as the afternoon and guest pick; it is a flavour identity more than a true tea variety. The Twinings standard at £3-£4.50 is the right entry point; trade up to specialty if the cup grabs you.
