London Fog

An Earl Grey latte named after a city it has little to do with. Invented by a café regular barred from the delights of coffee.

The short version

Born in Vancouver.
Named for London.

The London Fog is usually traced to a Vancouver café in the mid-1990s, where a pregnant regular asked for Earl Grey steeped in steamed milk.13 The tea is British. The drink, as far as anyone can document, is Canadian.

The story

A pregnancy, and no coffee

In the mid-1990s, Mary Loria was a regular at the Buckwheat Café in Vancouver. She was pregnant, had bad morning sickness, and couldn't face coffee.35 She asked for an Earl Grey tea bag steeped in steamed skim milk, with no water, and sweetened it with vanilla sugar from the condiment bar.23

She kept ordering it and told friends about it, and they started asking for it at other cafés.34 Years later she saw "London Fog" on menus and didn't recognize it as her drink at first. She says she has no idea who named it.24

Today
A standard order in Canadian and Pacific Northwest cafés. Still hard to find in London.2

A note on the record

Loria's account is the one most writers cite, and it rests mostly on her own memory. Other cafés have disputed it.3 We think it's the best-documented version, but it's an oral history, not a paper trail.

The name

Why "London Fog"?

Loria never named it, and nobody has come forward who did.2 These are the two usual guesses. Neither is documented.

Theory 01

It looks like fog

Steamed milk poured into dark tea turns it cloudy and grey. Most writers who explain the name point to this.4

Theory 02

It sounds British

Earl Grey is a British blend, usually said to be named for Charles Grey, 2nd Earl Grey, Prime Minister from 1830 to 1834. Even that link is uncertain.7 A London name fits an English-sounding tea, whoever came up with it.

The recipe

Make your own

Three ingredients. This is our everyday version. Loria's original skipped the water and steeped the tea bag straight in the steamed milk.2

Earl Grey tea
Brewed strong: 2 bags or a generous scoop of loose leaf, 3 minutes at 85–95°C. The bergamot is the whole point.
Steamed milk
Whole milk is richest. Steam it hot and silky rather than just frothy. Roughly equal parts milk and tea.
Vanilla
The original used vanilla sugar.3 Most cafés now use 1–2 pumps of vanilla syrup.

Method

  1. Brew 2 Earl Grey tea bags in ½ cup of hot water (85–95°C) for 3 minutes. Remove the bags without squeezing.
  2. Steam ½ cup of milk until hot and silky, around 65°C. No steamer? Heat it in a saucepan and froth with a whisk.
  3. Stir 1–2 teaspoons of vanilla syrup into the tea.
  4. Pour the milk over the tea and top with a little foam.

Variations

Oat or almond milk both work. Lavender syrup in place of vanilla is common, and so is honey. Some people add a pinch of cinnamon or cardamom.

Kyle's usual: Earl Grey with a splash of vanilla extract and a packet of stevia instead of syrup. Same idea, less sugar.

Details

Things worth knowing

After the pregnancy

Its inventor went back to coffee

Once the pregnancy was over, Loria returned to coffee,3 and she's still described as a big coffee drinker.2

The birthplace

The Buckwheat Café is gone

The café where Loria first ordered it has since closed.5

Spin-offs

There's a whole family of fogs

A Dublin Fog uses Irish Breakfast tea, a Halifax Fog uses maple syrup, and a Maui Fog uses coconut. Bars also make cocktail versions with scotch or gin.4

In London

London barely knows it

When Sprudge went looking, they couldn't find a London café serving one.2 It's still mostly a North American order.

Caffeine

About half the caffeine of coffee

An 8 oz cup of brewed black tea has around 48 mg of caffeine, against about 96 mg for brewed coffee. Steep time changes it a lot, and it's not caffeine-free.6
