Discover the Delight of an Iced London Fog Latte
The Iced London Fog Latte is more than just a drink; it’s an experience. It brings together the aromatic, citrusy notes of Earl Grey tea with the comforting creaminess of milk and a subtle sweetness. While traditional London Fogs are known for their warm, soothing qualities, the iced version offers a vibrant, cooling sensation that makes it perfect for warmer days or anytime you crave a chilled, elegant beverage. It’s a fantastic alternative to coffee for those who prefer tea or want to switch up their morning routine with something different.
What Exactly is a London Fog Latte?
A London Fog is a distinctive tea-based drink that originated in Vancouver, Canada. Traditionally, it’s made by combining Earl Grey tea with a hint of vanilla syrup and steamed milk, creating a comforting, creamy, and fragrant hot beverage. Our iced variation takes this classic recipe and transforms it into a refreshing cold drink by brewing the tea strong, chilling it, and then serving it over ice with your preferred cold milk. The star of the show is undeniably Earl Grey tea, a black tea blend famously flavored with oil of bergamot, which gives it its unique floral and citrusy aroma and taste.
Does an Iced London Fog Latte Contain Caffeine?
Yes, an Iced London Fog Latte does contain caffeine. The primary ingredient, Earl Grey tea, is a type of black tea, and all black teas naturally contain caffeine. The amount of caffeine can vary depending on the brand of tea, the brewing time, and the specific tea leaves used, but it generally offers a moderate caffeine boost, less than a typical cup of coffee but enough to help you feel energized and focused. If you’re sensitive to caffeine or prefer a nighttime treat, you can easily use decaffeinated Earl Grey tea for this recipe.
Can This Recipe Be Adapted for a Hot London Fog?
Absolutely! The beauty of the London Fog is its versatility. If you’re craving a warm and cozy drink, you can easily turn this recipe into a hot London Fog. Simply omit the chilling step and instead, add your freshly steeped, sweetened Earl Grey tea directly into a mug. Top it with warm, frothed milk for that classic, comforting experience.

Essential Ingredients for Your Perfect Iced London Fog Latte
One of the best aspects of making an Iced London Fog Latte at home is how incredibly simple the ingredient list is. You likely have most of these items in your pantry already! The key is to choose quality ingredients to achieve the best flavor. Here’s a closer look at what you’ll need:
The Star: Earl Grey Tea
Earl Grey tea: This is the heart of your London Fog. Earl Grey is a black tea blend characterized by its distinctive flavor derived from bergamot oil, a citrus fruit. This imparts a unique aroma and taste, with hints of floral and citrus notes that are both refreshing and sophisticated. For this recipe, you’ll need just one tea bag of Earl Grey. While tea bags are convenient, feel free to use loose-leaf Earl Grey (about 1 teaspoon per serving) for a potentially richer flavor.
Hot Water – The Brewing Foundation
Hot water: The right temperature of water is crucial for properly brewing black tea and extracting its full flavor without bitterness. Aim for water around 150-175°F (65-80°C) for optimal results. Using water that’s too hot can scorch the tea leaves, leading to a bitter taste, while water that’s too cool won’t extract enough flavor. We highly recommend using a temperature-controlled kettle, like our favorite Fellow Kettle, for precision.
Sweetener of Choice – Tailor to Your Taste
Sweetener: Customizing the sweetness is entirely up to your preference. You can use classic white granulated sugar, which dissolves easily in hot tea, or opt for natural sweeteners like maple syrup or honey for different flavor undertones. For an extra touch of convenience and flavor, consider making or buying a simple syrup. You can even infuse your simple syrup with vanilla bean, lavender, or other flavors to add another layer of complexity to your latte.
Your Preferred Milk – Creaminess Unlocked
Milk: This recipe is incredibly adaptable to any type of milk you prefer, allowing you to create a latte that perfectly suits your dietary needs or taste preferences. We especially enjoy it with almond milk or oat milk for their creamy texture and subtle sweetness, making for a delicious dairy-free option. However, traditional cow’s milk, soy milk, or even coconut milk will also yield fantastic results. Experiment to find your favorite!
Ice – The Crucial Chill Factor
Ice: It might seem obvious, but for an iced latte, a generous amount of ice is non-negotiable! Using plenty of ice ensures your drink stays perfectly chilled and refreshing, without becoming watered down too quickly. Large ice cubes melt slower, offering a longer-lasting cool sip.

Step-by-Step: Crafting Your Refreshing Iced London Fog Latte
This invigorating morning or afternoon drink is surprisingly simple to prepare, making it a perfect quick indulgence. Follow these three easy steps to create your perfect Iced London Fog Latte:
- Steep the Tea and Sweeten: Begin by placing your Earl Grey tea bag (or loose leaf tea in an infuser) into a mug or heat-safe bowl. Add your chosen sweetener directly into the hot water with the tea. Pour about ½ cup of hot water, ideally around 150-175°F (65-80°C), over the tea bag and sweetener. Allow it to steep for 3-4 minutes. This steeping time can be adjusted based on your desired tea strength – steep longer for a bolder flavor, shorter for a lighter one. Stir occasionally to ensure the sweetener fully dissolves into the hot tea.
- Rapid Chill for Optimal Flavor: Once the tea has steeped to your liking, remove and discard the tea bag (or infuser). It’s crucial to chill the brewed tea quickly to prevent excessive dilution when it meets the ice. Transfer the hot tea mixture into the fridge for about 10 minutes, or for an even faster chill, place the mug in an ice bath. This rapid cooling ensures the tea remains strong and flavorful.
- Assemble and Serve Over Ice: Fill a large glass generously with ice cubes. Pour the thoroughly chilled Earl Grey tea concentrate over the ice. Finally, top it off with ½ cup of your favorite cold milk. Give it a gentle stir to combine all the layers, and your refreshing Iced London Fog Latte is ready to be enjoyed immediately!

Creative Variations & Customizations
While the classic Iced London Fog Latte is perfect on its own, there are many ways to customize it to suit your personal taste or mood. Don’t be afraid to experiment with these exciting variations:
Transform it into a Hot Beverage
As mentioned, if you’re in the mood for warmth, simply skip the chilling step. After steeping and sweetening your Earl Grey tea, pour it into a mug and top with steamed or frothed milk for a cozy hot London Fog latte. A milk frother (either handheld or a machine) can elevate your hot latte experience.
Infuse with Flavored Syrups
Beyond plain sugar, explore flavored simple syrups to add a new dimension to your latte.
- Vanilla Syrup: Enhance the classic vanilla notes by using a vanilla-flavored simple syrup instead of plain sugar.
- Lavender Syrup: For a sophisticated and calming twist, try a homemade or store-bought lavender simple syrup. The floral notes beautifully complement the bergamot in Earl Grey.
- Rose Syrup: A delicate rose syrup can add a romantic and fragrant touch.
- Other Syrups: Experiment with caramel, hazelnut, or even a hint of mint syrup for a unique flavor profile.
Add a Vanilla Boost
If you don’t have vanilla syrup, you can still infuse your latte with rich vanilla flavor. Add a tiny splash of pure vanilla extract or a small piece of vanilla bean (removed after steeping) to the hot water while brewing your tea. This ensures the vanilla flavor is deeply integrated into the tea concentrate.
Spice It Up
For a touch of warmth and complexity, consider adding a pinch of ground cinnamon or a dash of cardamom to your brewed tea. These spices pair surprisingly well with Earl Grey and vanilla.
Make it Decaf
If you love the flavor but want to avoid caffeine, simply opt for decaffeinated Earl Grey tea bags or loose-leaf tea. This makes it a perfect evening treat without disrupting your sleep.
Batch Preparation for Effortless Mornings
Simplify your mornings by preparing a large batch of Earl Grey concentrate in advance. This means you can enjoy a delicious Iced London Fog Latte with minimal effort any day of the week!
To make a large batch (serves 6):
- 6 Earl Grey tea bags
- 2 tablespoons sweetener of choice
- 3 cups hot water (about 150-175°F / 65-80°C)
Instructions for Batch Preparation:
Combine the 6 Earl Grey tea bags and 2 tablespoons of your chosen sweetener in a large, heat-proof jar or pitcher. Pour the 3 cups of hot water over the tea bags and sweetener. Allow the tea to steep for 3-4 minutes, stirring occasionally to help the sweetener dissolve and ensure even brewing. After steeping, remove and discard the tea bags. Let the tea concentrate cool completely at room temperature, then transfer it to the refrigerator. Store the concentrate in an airtight container in the fridge for up to 5 days.
When you’re ready to serve from your batch, simply pour ½ cup of the chilled Earl Grey concentrate into an ice-filled glass. Top with your favorite cold milk, stir gently, and enjoy your instant, perfectly portioned Iced London Fog Latte!
