The London fog is proof that a great latte does not need espresso. This Earl Grey tea latte — strong bergamot-scented black tea, a touch of vanilla, and a generous pour of steamed, foamy milk — is creamy, floral, and deeply comforting, somewhere between a latte and a cup of afternoon tea. Despite the name, the drink was invented in Vancouver, Canada, and has since become a cafe staple across North America. The home version takes under ten minutes, needs no special equipment, and is easy to adapt for dairy-free, decaf, or iced versions. Here is the london fog recipe done properly, plus the technique details that make it taste like the cafe version.
What Is a London Fog?
A London fog is a tea latte: brewed tea takes the place of espresso, and steamed milk with light foam does the rest. The classic build is roughly half strong Earl Grey tea and half steamed milk, sweetened with vanilla syrup. Earl Grey is the non-negotiable element — it is black tea scented with bergamot, a fragrant citrus, and that floral-citrus perfume is what reads as “fog” through the milk. The vanilla rounds off the tea’s tannic edge and ties the citrus to the cream. If you enjoy drinks in this family, the London fog sits alongside the chai latte and the matcha latte as the third pillar of the tea-latte canon.
Ingredients (One 10-12 oz Mug)

- 2 Earl Grey tea bags (or 2 teaspoons loose leaf) — doubling the tea is the key to a latte that does not taste watery
- 180 ml (6 oz) hot water, just off the boil
- 180 ml (6 oz) milk — whole milk froths richest; oat is the best plant option
- 1-2 teaspoons vanilla syrup, or 1 teaspoon sugar plus a few drops of vanilla extract
- Optional: a small strip of lemon zest steeped with the tea brightens the bergamot beautifully
For the vanilla, homemade syrup takes two minutes: equal parts sugar and hot water, stirred with a split vanilla bean or a splash of extract. If you keep flavored syrups around, our guide to coffee syrup flavors covers making and storing them.
How to Make It, Step by Step
- 1. Brew the tea strong. Steep both tea bags in the 6 oz of hot water for 4 to 5 minutes, covered. You want it noticeably stronger than a normal cup, because the milk will dilute it by half.
- 2. Sweeten. Remove the bags (squeeze gently), then stir the vanilla syrup into the hot tea.
- 3. Steam or froth the milk. Heat the milk to about 140 to 150°F with a light, glossy foam. An espresso machine wand is ideal, but a handheld milk frother, French press plunger, or a lidded jar plus microwave all work — every method is covered in our guide to steaming milk without an espresso machine.
- 4. Combine. Pour the steamed milk over the tea, holding back the foam with a spoon, then cap the drink with the foam.
- 5. Finish. A tiny grating of lemon zest or a pinch of dried lavender on the foam is a lovely cafe-style touch.
If you have a steam wand and want to level up the presentation, tea lattes take latte art just like espresso drinks — the milk texture rules in our frothing milk for latte art guide apply directly, and a proper steaming pitcher makes the pour far easier to control.
Variations Worth Trying
Iced London fog: brew the tea double-strength, sweeten while hot, chill, and pour over ice with cold milk — or top with cold foam using the technique from our cold foam guide. Dairy-free: barista oat milk froths nearly as well as dairy and its gentle sweetness suits Earl Grey; our roundup of milk alternatives that steam well ranks the options. Decaf fog: decaffeinated Earl Grey makes this a perfect evening drink. Lavender fog: steep a quarter teaspoon of culinary lavender with the tea. Earl Grey creme: use a vanilla-blended Earl Grey and skip the added syrup. The milk-ratio logic here mirrors espresso drinks — if you are curious how those ratios shape texture, our cappuccino vs latte explainer shows the same principles applied to coffee.
Caffeine and Timing
A London fog is a moderate-caffeine drink. Black tea steeped strong contributes meaningfully less caffeine than espresso — a two-bag fog generally lands well below a single-shot latte (espresso runs about 63 mg per shot), making it a good mid-afternoon choice when a full coffee feels like too much. Steep time affects both strength and tannin: past about 5 minutes Earl Grey turns astringent, which fights the milk rather than melting into it. If your fog tastes bitter or chalky, shorten the steep before you change anything else; if it tastes thin, add a third tea bag rather than steeping longer.
Frequently Asked Questions
What is in a London fog latte?
Three things: strong-brewed Earl Grey tea, vanilla syrup, and steamed milk with light foam, typically in roughly equal parts tea and milk. Some cafes add lavender or use a vanilla Earl Grey blend.
Does a London fog have caffeine?
Yes, from the black tea — but notably less than a coffee latte. Using decaf Earl Grey makes an essentially caffeine-free version that tastes nearly identical.
Why does my London fog taste watery?
Single-bag tea diluted with an equal volume of milk is the usual culprit. Brew double-strength (two bags in 6 ounces) so the finished drink still tastes distinctly of bergamot after the milk goes in.
What milk is best for a London fog?
Whole milk gives the creamiest texture and most stable foam. Among plant milks, barista-formulation oat milk is the standout — it froths well and its natural sweetness complements Earl Grey’s citrus.
Can I make a London fog without a frother?
Absolutely. Heat the milk, then shake it hard in a sealed jar for 30 seconds, whisk it vigorously, or pump it with a French press plunger. Any of these produces enough foam for a satisfying fog.
