If you’ve ever ordered a “London Fog” at a coffee shop and wondered what was actually in your cup, the answer is simple: earl grey tea and steamed milk. That’s it. No espresso, no complicated syrups, just two ingredients that happen to work together in a way that feels far more indulgent than the ingredient list suggests.
The good news is that this drink is one of the easiest café-style beverages to recreate at home. You don’t need a $2,000 espresso machine, and you don’t need to be a barista. You need a good tea bag or loose-leaf blend, some milk, and about five minutes. This guide walks through exactly how to make earl grey tea with steamed milk, including ratios, equipment options for people without a steam wand, and a handful of variations worth trying once you’ve nailed the basics.
What Is Earl Grey Tea with Steamed Milk?
Earl grey tea with steamed milk is a black tea drink flavored with bergamot orange oil, strengthened into a concentrate, then topped with warmed, frothed milk. It’s often called a “London Fog,” a name that reportedly originated at coffee shops in Vancouver in the 1990s, even though the drink itself has no direct ties to London. The name stuck because it captures the drink’s soft, misty appearance once the milk foam settles on top.
A Latte Without the Coffee
Structurally, this drink borrows its format directly from an espresso latte: a strong base, a generous pour of steamed milk, and a layer of foam on top. Swapping espresso for concentrated earl grey tea gives you the same comforting, creamy mouthfeel without the caffeine intensity or the bitterness that some people find harsh in coffee drinks.
Why Bergamot and Milk Work So Well Together
Bergamot, the citrus oil that gives earl grey its distinctive aroma, is floral, slightly sweet, and a little bit sharp. On its own, a strong cup of earl grey can taste almost perfume-like. Milk rounds out those sharp edges, mellowing the citrus and letting the tea’s malty black-tea backbone come through. The result tastes closer to a creamy citrus-vanilla dessert than a straightforward cup of tea.
How Much Caffeine Is in It?
Because the base is black tea rather than espresso, a cup of earl grey tea with steamed milk typically contains somewhere around 40–70mg of caffeine per serving, depending on steep time and how many tea bags you use. That’s roughly a third to half the caffeine of a standard cup of coffee, which makes this a popular choice for an afternoon drink when a full caffeine hit feels like too much but plain herbal tea feels like too little.
What You’ll Need
Before you start, it helps to know what actually makes a difference in the final cup versus what’s optional.
Choosing Your Earl Grey Tea
Loose-leaf earl grey: Generally gives a fuller, more layered bergamot flavor than bagged tea, and lets you control strength precisely.
Earl grey tea bags: Perfectly fine, and often more convenient. Look for a brand that lists “bergamot oil” or “oil of bergamot” rather than artificial flavoring for a cleaner citrus note.
Lavender earl grey or “London Fog blend” bags: Many brands now sell a version pre-blended with lavender or vanilla specifically for this drink. It’s a good shortcut if you want a floral note without buying separate lavender.
Picking the Right Milk
Whole milk is the classic choice because its fat content produces the richest texture and the most stable foam. That said, this drink is forgiving:
Whole milk: Creamiest texture, holds foam well.
2% milk: Slightly lighter but still froths nicely.
Oat milk (barista blend): The closest plant-based option in terms of froth and creaminess; regular oat milk can froth thinner.
Almond or skim milk: Will steam and warm fine, but expect less foam and a thinner body.

Optional: honey, sugar, or vanilla syrup to sweeten
The Perfect Earl Grey Tea and Steamed Milk Ratio
Standard Ratio
The most common and reliable earl grey tea and steamed milk ratio is roughly equal parts concentrated tea to milk, adjusted slightly depending on how strong you like the tea flavor to come through.
Component
Amount (12 oz cup)
Notes
Water
4–5 oz
Just off the boil, around 200°F
Earl grey tea
1–2 tea bags or 2 tsp loose leaf
Steeped double-strength
Steamed milk
5–6 oz
Warmed to 150–160°F, lightly frothed
Sweetener
1–2 tsp honey, sugar, or syrup
Optional, to taste
Adjusting Strength and Sweetness
If you want a more pronounced tea flavor, use two tea bags instead of one, or extend the steep time by a minute. If the bergamot flavor feels too strong or perfume-y, cut back to a single bag and add a touch more milk. Honey tends to pair especially well here because its floral notes echo the bergamot, while vanilla syrup pushes the drink closer to a dessert-style London Fog.
Step-by-Step: How to Make Earl Grey Tea with Steamed Milk
Step 1: Steep the Tea Double-Strength
Bring water just off the boil — around 200°F, just under a full rolling boil — and pour it over your tea bags or loose leaf, using about half the water you’d normally use for a regular cup. Cover the mug or teapot while it steeps; covering traps heat and keeps the aromatic bergamot oils from evaporating off before they’ve had a chance to infuse. Let it sit for 4–5 minutes. Because this concentrate will be diluted with an equal amount of milk, brewing it stronger than usual is what keeps the bergamot flavor from getting lost once everything is combined.
Step 2: Steam the Milk
While the tea steeps, warm your milk to around 150–160°F — hot enough to feel steamy and slightly too hot to sip immediately, but well below boiling. If you’re using a thermometer, this is roughly the point where the milk starts to feel uncomfortable to hold your hand against the side of the pitcher. Froth it lightly so you get a thin, silky foam rather than the stiff, cappuccino-style foam used for espresso drinks — this tea only needs a soft cap of foam, not a dense, spoonable one. Over-frothing can also make the drink taste more diluted, since foam is mostly air.
Step 3: Combine and Sweeten
Remove the tea bags or strain out the loose leaves. Add your sweetener directly to the hot tea concentrate and stir until dissolved — it mixes in far more easily now than after the milk goes in. Then pour the steamed milk over the tea, holding back the foam with a spoon until the end, then spooning the foam on top. Finish with a light dusting of cinnamon or a few extra lavender buds if you’re feeling fancy.
Common Mistakes to Avoid
Over-steeping the tea: Earl grey turns bitter and astringent past 5–6 minutes, which milk won’t fully mask.
Boiling the milk: Milk that gets too hot can scald, developing a slightly burnt, skin-forming texture. Keep it under 170°F.
Adding cold milk to hot tea without warming it first: This works in a pinch, but you lose the signature creamy, latte-like texture that makes the drink special.
Sweetening after mixing everything together: Sugar and honey dissolve far better into hot tea than into a milk-diluted mixture.
How to Steam Milk Without an Espresso Machine
You don’t need a steam wand to get a good result. Here are three reliable methods.
Stovetop Whisk Method
Heat milk in a small saucepan over medium-low heat until steaming, watching closely so it doesn’t boil. Remove from heat and whisk vigorously for 20–30 seconds, or use a small handheld whisk in a circular motion, until you see a light layer of foam form on top.
Mason Jar Microwave Method
Fill a jar no more than halfway with milk, screw on the lid, and shake vigorously for 30–45 seconds until noticeably frothy. Remove the lid and microwave for 30–45 seconds until hot. The foam will stabilize and rise to the top as it heats.
Handheld Frother Method
Warm milk in the microwave or on the stovetop, then insert a battery-powered handheld frother and whisk for 15–20 seconds. This is the closest at-home approximation to café foam and is worth the roughly $10–15 investment if you plan on making this regularly.
Stir in half a teaspoon of vanilla extract or a pump of vanilla syrup along with your sweetener. This is the closest match to the classic café version of a London Fog and softens the bergamot’s sharper citrus notes even further.
Lavender Earl Grey
Add a small pinch of culinary lavender buds to the tea while it steeps, or use a pre-blended lavender earl grey tea. Go light — lavender turns soapy-tasting quickly if oversteeped.
Iced Earl Grey with Steamed Milk
Brew the tea double-strength as usual, then let it cool slightly and pour over a full glass of ice. Top with cold milk that’s been frothed using a handheld frother rather than steamed, since heating isn’t necessary here. The cold foam still gives you that same layered, café-style look.
Frequently Asked Questions
Is earl grey tea with steamed milk the same thing as a London Fog?
Yes. “London Fog” is simply the café name for earl grey tea combined with steamed milk, usually sweetened with vanilla syrup.
Can I use a different black tea instead of earl grey?
You can, but you’ll lose the bergamot flavor that defines this particular drink. Any black tea will steam and pair with milk fine, but it won’t taste like a London Fog without the bergamot.
What’s the best milk for steaming with tea?
Whole milk gives the richest texture and most stable foam. For a dairy-free option, an oat milk labeled “barista blend” froths most similarly to dairy.
Why did my milk curdle or separate?
This usually happens when milk is overheated past boiling, or when very acidic tea is added to milk that’s already cooling. Keep milk under 170°F and add it to the tea rather than the other way around.
Can I make this drink dairy-free?
Yes. Oat milk, especially a barista-blend version formulated to froth and hold heat, is the closest substitute. Almond and soy milk work too, though foam will be thinner.
Do I need an espresso machine to make this?
No. A saucepan and a whisk, a mason jar and a microwave, or a $10 handheld frother will all get you a good result without any specialized equipment.
How long should I steep the tea before adding milk?
4–5 minutes is the sweet spot for a double-strength concentrate. Steeping much longer pulls out excess tannins, which milk will only partially soften, leaving a slightly chalky or bitter aftertaste.
Can I make this ahead of time for multiple servings?
You can brew a batch of the tea concentrate ahead and refrigerate it for up to a few days, then simply reheat a portion and add freshly steamed milk when you’re ready to drink it. Steaming the milk fresh each time gives a noticeably better texture than trying to reheat pre-steamed milk.
Final Thoughts
Earl grey tea with steamed milk is one of those drinks that seems more complicated than it actually is. Once you’ve got the basic ratio down — double-strength tea, warmed and lightly frothed milk, a bit of sweetener — you can make a café-quality London Fog at home in less time than it takes to walk to the coffee shop and wait in line.
The beauty of this drink is how easily it adapts to what you already have on hand. No frother? A whisk and a steady arm will do. No dairy? A good oat milk gets you most of the way there. No vanilla syrup? A spoonful of honey does the job just as well. Start with the classic version to get a feel for the ratio, then branch out into the vanilla, lavender, or iced variations once you know what balance of tea, milk, and sweetness you like best.
