London Fog Tea Latte: A Hot and Iced Earl Grey Recipe

A London Fog is an Earl Grey tea latte: black tea scented with bergamot, milk, and a little vanilla. It can be a hot cup with steamed milk or a cold glass poured over ice. The part that needs attention is the tea. Milk and ice both dilute it, so a normal mug of Earl Grey often disappears once the latte is assembled. Brewing the tea as a short concentrate solves that problem without leaving the leaves in hot water until they turn harsh.

The hot and iced amounts below are proposed starting ratios, assembled from published tea-producer methods, not a report of cups personally tested by us. Use your Earl Grey package's temperature and time when it gives them. The Earl Grey guide explains the tea and bergamot; this page is about turning that tea into one reproducible drink. Plum Deluxe's iced London Fog recipe uses Earl Grey, milk, vanilla, sweetener and ice, while Harney & Sons recommends concentrated tea for iced service. Those are the starting ideas, not a claim that every blend needs the same dose.

Start with the tea, then choose the milk

Use an Earl Grey you would drink on its own. The defining flavor is bergamot over a black-tea base. A flavored blend that already contains vanilla may need less syrup; a lighter black-tea base may need less milk to stay recognizable. Loose leaf gives you a way to weigh the tea, but a bag is fine if it is the Earl Grey you have. The goal is a clear tea flavor after milk, not a particular brand or grade.

For one cup, gather Earl Grey, water, milk or an unsweetened plant milk, and a little vanilla syrup or vanilla plus a sweetener you can dissolve. A milk frother is optional. A saucepan, microwave-safe jug or other normal kitchen method can warm the milk; a whisk can make some foam. No espresso is involved. If you leave out vanilla, you still have an Earl Grey latte, but it will not have the usual London Fog profile.

Avoid making the tea stronger only by steeping it longer. Concentration is about more leaf for a smaller volume of water. Longer exposure can increase astringency as well as strength. Start with the time on your package and strain when the timer ends. One Harney blend gives a five-minute boiling-water instruction; your blend may give another. This recipe's 3-to-4-minute interval is a practical starting range for a standard black Earl Grey, not a universal rule.

One-cup ratio card: hot and iced

This table keeps the hot and iced versions side by side. The iced glass starts with less water because melting ice adds liquid. The tea amounts are suggested starting points; change one variable at a time after tasting your own blend.

For one serving Hot London Fog Iced London Fog
Earl Grey About 4 g loose leaf, or two bags About 4 g loose leaf, or two bags
Water for tea 120 ml 100 ml
Milk 120 ml, warm or steamed 120 ml, cold
Vanilla syrup 5 to 10 ml, to taste 5 to 10 ml, to taste
Ice None Enough to fill a glass; it will melt and dilute the tea
Start with Tea and milk at roughly 1:1 before foam A smaller tea concentrate, milk and ice

A scale is useful because a teaspoon of large, twisted leaf holds a different mass from a teaspoon of small broken leaf. If you do not have one, use the package's per-cup amount as the base and make the water volume smaller, rather than inventing a spoon-to-gram conversion. For bagged tea, two bags in 100 to 120 ml water are simply a starting choice for a milky drink; one strong bag may be enough. The finished volume varies with foam, the amount of ice, and how much tea the leaves retain.

Hot London Fog, step by step

  1. Brew a short Earl Grey concentrate. Put the suggested leaf or bags in 120 ml hot water, using your blend's temperature instruction. If none is given, start near boiling for a black Earl Grey and set a 3-to-4-minute timer. Strain or remove the bags promptly. Do not keep the leaves in the cup while heating milk.
  2. Warm the milk separately. Heat 120 ml until pleasantly hot without boiling it. Froth only if you want a foamy top. With no frother, a whisk in a small pan or jug is enough for a light layer; you do not need café equipment to make the drink.
  3. Add vanilla and taste. Stir 5 ml of vanilla syrup into the hot tea first. If you use vanilla extract instead, add just a small amount and sweeten separately to your taste. A syrup blends more easily into the finished cup than dry sugar added after foam.
  4. Combine. Pour the milk into the tea, keeping the foam back if you want to spoon it on top. Taste before adding more syrup. If you can still identify Earl Grey and bergamot underneath the milk, the balance is working for your blend.

Iced London Fog without a watery finish

For the iced version, brew the tea in 100 ml water with the same suggested leaf amount. Strain it at the selected time and dissolve the vanilla syrup while the tea is still warm. Let the concentrate cool a little in a heat-safe vessel. Fill a glass with ice, pour in 120 ml cold milk, then add the tea concentrate and stir. This is a hot-brewed iced drink. It is ready when assembled; it is not a cold-brew recipe that takes hours.

Why reduce water? If you make a full 240 ml mug of tea and add 120 ml milk plus ice, the bergamot can be hard to find. If you instead brew a smaller, stronger tea, the ice's melt has room in the balance. Harney's iced-tea guidance similarly uses stronger tea before pouring over ice. The ratio card does not predict exactly how much your ice will melt, so judge the finished glass after a few minutes rather than claiming a precise final volume.

Want a less creamy glass? Use a little less milk, not a much longer steep. Want it richer? Increase milk modestly but keep enough tea concentrate that the Earl Grey remains present. If the glass tastes sweet but not like tea, adding more syrup is moving in the wrong direction. Our cold-brew tea guide covers a separate make-ahead method; keep its cold extraction time distinct from this quick hot-brew version.

Milk, vanilla and sweetness choices

Dairy milk gives the classic soft, creamy profile. Oat or soy milk can work without changing the method; use a version you already enjoy with black tea. A flavored or sweetened milk changes how much vanilla syrup you need, so start with less. If you use a vanilla-flavored Earl Grey, taste the plain concentrate before adding syrup. The recipe should let bergamot remain identifiable, not turn into vanilla milk with a tea-colored tint.

Simple syrup dissolves in both hot and iced versions. Ordinary sugar is easiest to dissolve in the warm tea before adding milk or ice. Honey can be stirred into warm tea too, but its flavor will change the drink. None is required in a fixed amount; the 5-to-10-ml range in the table is a starting point for a sweetened latte, and you can use less or none. If you skip both sweetness and vanilla, you are making a different, still valid Earl Grey-with-milk drink.

Fix the cup you actually made

What you notice Likely adjustment for the next cup Keep this constant
Mostly milk, little Earl Grey Increase leaf or bag strength, or reduce milk slightly Keep steep time at the blend's recommended interval
Bitter or rough tea Shorten the steep toward the package's lower end; strain promptly Do not try to hide bitterness under more syrup
Iced cup becomes thin Use the smaller tea-water volume and less ice melt before tasting Keep the milk amount steady while testing
Too sweet, bergamot lost Start with 5 ml syrup or omit it if the blend is already vanilla-scented Leave the tea amount unchanged for one test
Mostly foam in the first sip Froth less, pour liquid milk first, then stir Keep the same tea-to-milk measure

Change just one thing per cup. Otherwise you will not know whether the improvement came from a stronger tea concentrate, less milk or less syrup. The tea-brewing mistakes guide has the broader extraction checks if plain Earl Grey already tastes harsh before any milk is added.

Can I use a single tea bag? Yes, especially a large sachet or strong blend. Begin with the package instructions, keep the concentrate small and adjust next time if milk overwhelms it. The two-bag table is a starting point, not a requirement.

Can I make it without a frother? Yes. Warm milk, whisk briefly if you want foam, and pour. The tea, milk and vanilla balance matters more than a café-style cap.

Does iced London Fog have to be cold-brewed? No. This version brews Earl Grey hot, strains it, then cools it with cold milk and ice. Cold brew is a separate slow method with its own leaf and time choices.

Keep the tea step repeatable

The one step a timer handles well is removing the Earl Grey at the intended minute. The Tea Timer app can help you set a black-tea timer on iPhone or Apple Watch while you warm the milk. The app does not choose your syrup or claim a perfect ratio for every Earl Grey; it helps you reproduce the leaf-and-time choice you liked. For another milk-based tea, compare the matcha latte and hojicha latte, whose tea preparation works differently.

Get Tea Timer on the App Store if you want that timing step beside the cup. For your next cup, keep the hot or iced row as written, then note one change you want. After two or three cups, you will have a ratio for your tea and your milk, rather than a universal recipe that only worked for someone else's ingredients.
