London Fog Tea Concentrate Recipe: Imagine sipping a creamy, comforting latte infused with delicate notes of vanilla and lavender, all built on a strong base of Earl Grey tea. That’s the London Fog. At its core, this drink is a tea latte, but it stands out because of its soothing balance between citrusy bergamot from Earl Grey, the calming floral aroma of lavender, and the sweet, velvety touch of vanilla. Unlike traditional black tea lattes, the London Fog offers both energy and relaxation—a rare mix that makes it ideal for mornings, cozy evenings, or even as a mid-day pick-me-up.
But while cafés make it by the cup, a London Fog Tea concentrate is far more convenient for tea lovers who want that café-style experience at home. Instead of brewing from scratch every single time, a concentrate allows you to whip up a latte in minutes—simply mix with steamed milk, and your drink is ready.
Origins and Popularity of the London Fog Latte
The London Fog is believed to have originated in Canada, particularly in Vancouver, during the 1990s. Local stories say it was created by a pregnant woman who wanted a soothing alternative to coffee but still desired a warm, comforting drink with depth. Over time, its creamy vanilla-lavender flavor gained popularity across North America and eventually worldwide.
Today, you’ll find the London Fog on menus at big coffee chains like Starbucks and countless indie cafés. Its calming qualities and customizable flavor profile make it one of the most beloved tea lattes. Many people even compare it to a “hug in a mug” because of how cozy and nurturing it feels.
Why Make a Concentrate Instead of Single Servings?
While making a single London Fog latte is not difficult, it can be time-consuming if you drink it often. Preparing a concentrate solves that problem beautifully. With a batch of concentrate sitting in your fridge, you can pour, mix, and enjoy a latte in seconds.
Other benefits of making a concentrate include:
- Consistency: Every cup has the same strength and balance.
- Convenience: No waiting for tea to steep each time.
- Cost-effectiveness: Cheaper than daily café runs.
- Versatility: Use the concentrate not only for lattes but also in baking, cocktails, and desserts.
Making your own concentrate means you’re in charge—you can control sweetness, experiment with different flavors, and make it as strong or mild as you like.
Ingredients You’ll Need for London Fog Tea Concentrate
Key Ingredients for Authentic Flavor
To capture the essence of a true London Fog, you’ll need a few non-negotiable ingredients:
- Earl Grey Tea – The backbone of the recipe. Earl Grey is black tea flavored with oil of bergamot (a type of citrus). It gives the drink its signature flavor. Loose leaf works best, but high-quality tea bags are fine too.
- Water – Fresh, filtered water is essential for a clean, crisp taste.
- Vanilla Extract – Pure vanilla brings warmth and sweetness. This is what makes the London Fog feel almost dessert-like.
- Lavender Buds – Dried culinary lavender adds that calming floral aroma. Go easy—too much lavender can overpower the drink.
- Sweetener – Traditionally, cane sugar or simple syrup is used, but you can substitute honey, maple syrup, or agave depending on preference.
These core ingredients form the heart of the concentrate. Without them, you won’t get that classic balance of flavors.
Optional Ingredients for Customization
The beauty of homemade recipes is customization. Here are some ways to elevate your London Fog concentrate:
- Citrus zest (lemon or orange) for extra brightness.
- Cinnamon stick or cardamom for a spiced twist.
- Almond extract for a nutty undertone.
- Floral syrups like rose or elderflower to create a more fragrant variation.
Substitutions and Variations
Don’t have lavender? Try:
- Chamomile for a mellow, honey-like flavor.
- Rose petals for floral sweetness.
- No floral at all if you prefer a simpler Earl Grey vanilla latte.
Not a fan of sugar?
- Use stevia, monk fruit, or erythritol for a sugar-free version.
- Honey is excellent if you want a richer, more soothing drink.
Dairy-free?
- The concentrate itself contains no milk, so it’s naturally vegan. Pair it with oat milk, almond milk, or coconut milk for a creamy dairy-free latte.
Tools and Equipment Needed
Essential Kitchen Tools
Before getting started, make sure you have:
- A medium saucepan for boiling water and steeping tea.
- A fine mesh strainer or cheesecloth to remove tea leaves and lavender.
- A wooden spoon for stirring ingredients gently.
Best Storage Containers for Concentrate
Since this recipe makes enough for multiple servings, storage matters. The best options include:
- Glass bottles or mason jars with airtight lids (to preserve flavor).
- Pour spout bottles if you want café-style convenience.
- Refrigerator-safe containers that won’t absorb flavors or odors.
Helpful Add-ons for Flavor Enhancement
- Milk frother or steamer if you’re making lattes often.
- Tea timer to ensure perfect steeping.
- Small funnel for mess-free pouring into storage containers.
Step-by-Step Guide to Making London Fog Tea Concentrate
Step 1 – Boiling the Water and Preparing Tea
Start by bringing fresh water to a boil. Place 3–4 Earl Grey tea bags (or loose-leaf tea in an infuser) into a heatproof container. Pour the hot water over the tea and let it steep for about 5 minutes. This will create a strong, bold tea base for your concentrate.
Step 2 – Adding Vanilla and Sweetener
Once the tea is steeping, stir in vanilla extract and your choice of sweetener—classic sugar, honey, or a sugar substitute if you prefer. The vanilla adds warmth and depth, while the sweetness balances out the tannins of the strong tea.
Step 3 – Infusing with Lavender and Steeping Properly
Add a small pinch of dried culinary lavender (too much can overpower the flavor) to the hot tea. Let the tea, vanilla, and lavender steep together for another 2–3 minutes, allowing the floral notes to blend into the citrusy bergamot of the Earl Grey.
Step 4 – Straining and Cooling
Remove the tea bags (or strain out the loose tea and lavender) to prevent bitterness. Let the concentrate cool to room temperature before transferring it to a jar or bottle.
Step 5 – Storing the Concentrate
Seal the cooled concentrate in an airtight container and store it in the refrigerator for up to a week. To serve, mix 1 part concentrate with 1–2 parts steamed milk (dairy or non-dairy) to create your own creamy, café-style London Fog latte at home.
How to Use London Fog Tea Concentrate
Making a Classic London Fog Latte
The simplest and most popular way to use your concentrate is to prepare a latte. Mix ½ cup of tea concentrate with ½ cup of steamed milk (dairy or plant-based). Froth the milk for a velvety texture. Top with a sprinkle of dried lavender or cinnamon for garnish.
Iced London Fog Tea Version
For a refreshing twist, pour the concentrate over ice and mix with cold milk. You can even add a splash of vanilla cold foam on top for a coffee-shop-style iced latte.
Creative Uses in Baking and Desserts
Your London Fog concentrate doesn’t just belong in a cup. Try using it in:
- Cake batters for a subtle Earl Grey-vanilla flavor.
- Frostings and glazes for cupcakes.
- Homemade ice cream bases.
- Cocktail mixers (pair it with gin or vodka).
Tips and Tricks for the Perfect Concentrate
Balancing Strength and Sweetness
The magic of a London Fog concentrate lies in finding that sweet spot between bold tea flavor and gentle sweetness. Too much tea and the drink turns bitter; too much sugar and it feels more like a dessert than a cozy latte. The golden ratio many home baristas follow is one part concentrate to one part milk when serving. But since taste is personal, here’s a simple way to balance:
- Start Strong – Brew your Earl Grey slightly stronger than you think you’ll need. Remember, it will be diluted later with milk.
- Add Sweetener Gradually – Instead of dumping sugar all at once, add a few tablespoons at a time and taste as you go. You can always add more later, but you can’t take it away once it’s dissolved.
- Test with Milk – Sometimes the concentrate tastes too bold on its own, but when mixed with milk, it mellows out beautifully. Always sample it as a latte before adjusting sweetness.
Best Practices for Storage and Shelf Life
Your homemade London Fog concentrate will keep its rich flavors for about 7–10 days in the fridge if stored in a sealed glass jar or bottle. Always allow it to cool completely before refrigerating—this prevents condensation inside the container, which could water down the flavor.
For longer storage:
- Freeze in ice cube trays and pop them out as needed. One cube is perfect for a single latte.
- Store in small glass bottles instead of one large container. This way, you only open what you need, keeping the rest fresher.
Flavor Combinations to Try
Once you master the classic recipe, experiment! A few variations include:
- London Fog Chai – Add a cinnamon stick, star anise, and cloves while brewing.
- Citrus Twist – Add a strip of fresh orange or lemon zest.
- Holiday Edition – Stir in nutmeg, vanilla bean, or peppermint extract.
These twists allow you to create seasonal versions of your favorite tea latte—perfect for impressing guests or just spoiling yourself.
Health Benefits of London Fog Tea
Nutritional Value of Black Tea
Earl Grey tea, the base of the London Fog, is packed with antioxidants like catechins and flavonoids. These compounds help reduce inflammation, support heart health, and may even boost metabolism. Compared to coffee, black tea offers a gentler caffeine lift, keeping you alert without causing jitters.
Benefits of Lavender and Vanilla
- Lavender: Known for its calming properties, lavender may reduce anxiety, improve sleep, and aid digestion. Its soothing aroma alone is enough to relax your nervous system after a stressful day.
- Vanilla: Beyond flavor, vanilla is rich in antioxidants and is thought to support mood regulation. That’s one reason a London Fog feels so comforting—it’s like a natural mood booster in a cup.
Lower Sugar Alternatives
If you’re health-conscious, you can still enjoy a London Fog without loading up on sugar. Here are some ideas:
- Stevia or monk fruit – zero-calorie sweeteners that blend smoothly.
- Honey – adds sweetness and antimicrobial benefits.
- Coconut sugar – a lower-glycemic option with a caramel-like taste.
This means you can indulge daily without guilt, making it one of the healthier latte-style drinks out there.
Common Mistakes to Avoid
Over-Steeping the Tea
Black tea becomes bitter if steeped too long. The ideal steeping time for Earl Grey is 3–5 minutes. Anything longer releases too many tannins, which results in a harsh, astringent flavor. If you want a stronger concentrate, add more tea leaves rather than extending the steeping time.
Using Artificial Vanilla Instead of Pure
Pure vanilla extract has a warm, complex sweetness that balances the bergamot in Earl Grey. Artificial vanilla tends to taste sharp and one-dimensional, which can ruin the delicate balance of the drink. Since vanilla is a key ingredient, always opt for the real thing—even if it costs a little more.
Not Balancing Milk-to-Concentrate Ratio
The most common mistake is either drowning the tea in milk or not adding enough milk to balance the bold tea base. The standard ratio is equal parts concentrate and milk, but you can adjust from there. Remember, the concentrate should shine through, not disappear.
London Fog Tea Concentrate vs. Coffee Concentrates
Caffeine Levels Compared
One big reason people choose London Fog over coffee is caffeine content. A standard cup of Earl Grey tea has about 40–60 mg of caffeine, compared to 95–150 mg in coffee. This makes London Fog a gentler option for those sensitive to caffeine or anyone wanting a soothing evening drink without staying awake all night.
Taste and Aroma Differences
Coffee concentrates are bold, bitter, and robust. They pair well with caramel or chocolate but can overwhelm subtle flavors. Tea concentrates like the London Fog, on the other hand, are lighter, floral, and slightly citrusy. They’re more versatile for baking, desserts, and even cocktails where coffee might dominate.
When to Choose Tea Over Coffee
- Morning Calm: Tea gives a smoother, less jittery start to the day.
- Afternoon Pick-Me-Up: London Fog provides energy without the crash.
- Evening Comfort: Unlike coffee, a tea latte feels calming, especially with lavender.
So if you’re torn between coffee and tea, London Fog concentrate might be your middle ground—energizing enough to keep you going, but gentle enough to relax you.
Storage, Shelf Life, and Safety
How Long Does Homemade Concentrate Last?
When stored properly in the refrigerator, London Fog concentrate stays fresh for 7–10 days. You’ll know it’s time to toss it if the flavor turns flat, the color darkens excessively, or if you notice any odd smell.
Best Refrigeration Practices
- Always use sterilized glass jars or bottles. Rinse them in boiling water before storing your concentrate.
- Keep the concentrate sealed tightly. Oxygen exposure can dull the flavors.
- Store it at the back of the fridge, where the temperature is most consistent.
Freezing for Longer Shelf Life
If you’d like to prepare a big batch, freezing is your best bet. Pour cooled concentrate into ice cube trays and freeze. Once solid, transfer cubes into a freezer-safe bag. This way, you can grab one cube at a time and thaw it quickly in hot milk. Properly frozen, it can last up to 3 months without losing flavor.
FAQs about London Fog Tea Concentrate Recipe
Q1: Can I double the recipe for a larger batch?
Yes! Just double the ingredients while keeping the same ratios. Be sure to use a larger pot and store the concentrate in multiple jars for freshness.
Q2: What’s the best milk for London Fog lattes?
Oat milk is a fan favorite for its creamy texture and natural sweetness. Almond milk gives a nutty flavor, while coconut milk adds richness. Traditional whole milk works beautifully too.
Q3: Does the concentrate taste good on its own without milk?
Yes—it’s essentially a strong, sweetened Earl Grey tea. Some people enjoy it over ice as a tea tonic or mix it with sparkling water for a refreshing twist.
Q4: How do I make a vegan version?
The concentrate itself is vegan. Simply pair it with plant-based milk like oat, almond, soy, or coconut, and use a vegan-friendly sweetener such as agave syrup or maple syrup.
Q5: Can kids drink London Fog Tea Concentrate?
Since it contains caffeine, it’s best served in small amounts or made with decaf Earl Grey if you want a kid-friendly version. The floral vanilla flavor makes it appealing even to younger taste buds.

By making it yourself, you control the flavor strength, sweetness, and even the type of milk or sweetener you pair with it. You can enjoy it hot on a chilly morning, iced on a warm afternoon, or even use it in desserts and cocktails.
The beauty of this recipe is its flexibility—it works for anyone, whether you’re a busy professional, a health-conscious tea drinker, or someone who simply loves a cozy, aromatic drink. Plus, it saves money compared to daily café visits, while still giving you that indulgent coffeehouse vibe.
