The London Fog. Earl Grey, with the lights low.
Brew it stronger than you'd dare drink it. Sweeten while it's hot. Then drown it in warm milk and crown it with foam. Bergamot and steam — nothing complicated about it.
The short answer
A London Fog is an Earl Grey tea latte: brew Earl Grey double-strength in a little water, sweeten it with vanilla while it's hot, then top it with steamed, frothed milk. The bergamot has to be strong enough to carry through the milk — so over-brew the tea on purpose.
The idea
It's the one that turns a humble bag of Earl Grey into something you'd order out. The whole trick is restraint in reverse: brew the tea far stronger than you'd ever sip it neat, because the milk is about to halve it. Get the concentrate right and the rest is just steam and a steady pour.
The method
6 steps. No shortcuts.
- 01
Brew it strong
One Earl Grey sachet (or a heaping teaspoon of loose) in just 4oz of fully boiled 212°F water. Steep 4–5 minutes — longer and stronger than a normal cup. You want a concentrate, because the milk is about to cut it in half.
- 02
Sweeten while it’s hot
Stir a teaspoon of vanilla syrup — or honey and a single drop of vanilla extract — into the hot tea, while it still dissolves clean. This is the line between a fog and a beige cup of milk.
- 03
Froth the milk
Warm about 4oz of milk and run the frother until it turns glossy and doubles. Whole milk for richness, oat for the best foam of the non-dairy options. Stop while it’s still wet, not stiff.
- 04
Marry them
Pour the warm milk into the tea concentrate slowly, holding the foam back with the bowl of a spoon so the liquid goes in first. The colour should turn the soft tan of milky tea.
- 05
Crown it
Spoon the held-back foam on top. A dust of vanilla, or a single twist of orange peel, if the moment calls for it. Don’t stir it back in — the foam is the point.
- 06
Sip before it settles
A London Fog is best in the first few minutes, while the foam still holds and the bergamot is still rising off the top. Don’t let it sit and go flat.
What it takes
The short shopping list.
Loose leaf
Vahdam Imperial Earl Grey Loose Leaf
The bergamot base. Dose it heavy and brew it strong — the perfume has to carry all the way through the milk.
Pyramid bags
Harney & Sons Paris Tea — 50 Sachets
The shortcut to a dessert fog. Caramel and vanilla are already in the sachet, so you can skip the syrup entirely.
Accessories
Bodum Bistro Battery-Powered Milk Frother
No espresso machine required. Two AA batteries and fifteen seconds gets you a glossy, pourable foam.
House rule
Over-brew the tea on purpose. A fog made with a timid cup is just warm milk with a memory of bergamot.
FAQ
London Fog, answered.
What is a London Fog? +
A London Fog is an Earl Grey tea latte: strong-brewed Earl Grey sweetened with vanilla and topped with steamed, frothed milk. The bergamot in the Earl Grey is what sets it apart from a plain milky tea.
What tea do you use for a London Fog? +
Earl Grey — black tea scented with bergamot. A heavily-bergamot Earl Grey carries best through the milk, and a vanilla-and-caramel version like Harney Paris lets you skip adding syrup. Lady Grey works for a softer, more citrus-forward version.
Can you make a London Fog without an espresso machine? +
Yes. Brew the tea double-strength so it survives the milk, then froth warmed milk with a cheap handheld battery frother. No steam wand or espresso machine is needed.
What milk is best for a tea latte? +
Whole milk gives the richest body. Among non-dairy options, oat milk froths and holds foam the best and its mild sweetness suits Earl Grey — almond and soy work but foam thinner.
