Iced London Fog (Iced Earl Grey Latte)

A closeup of the top of two iced London fogs.

This iced London fog recipe is made with Earl Grey tea, whole milk, and lavender syrup. Undernotes of bergamot and lavender make this a truly delightful drink. The recipe makes one lightly sweetened, iced Earl Grey tea latte—a perfectly refreshing drink for warmer months.

I made this iced latte with my homemade lavender simple syrup, but any lavender syrup, like Monin lavender syrup, will work in this recipe. This iced lavender latte complements the lavender in my lemon lavender macarons and the Earl Grey in my homemade Earl Grey marshmallows.

Ingredients for Iced London Fog

An iced London fog has only a handful of ingredients. Because there are so few ingredients, it’s recommended to use high-quality ingredients when you can. You’ll be able to taste the difference; trust me!

  • Earl Grey tea. I used an Earl Grey with vanilla for this recipe. Those are my favorite kinds of Earl Grey, even though they aren’t technically traditional. Use your favorite Earl Grey blend here—with or without vanilla.
  • Hot water. Used to brew the tea. A smaller amount than normal results in a stronger brew that won’t be watered down too much by the ice or milk.
  • Whole milk. Whole milk gives this drink a richness that lowfat or nonfat milk simply can’t provide, but you are welcome to use your milk of choice (cow’s milk or even plant-based).
  • Lavender syrup. I use my homemade lavender simple syrup recipe, but any lavender syrup will work. If you don’t want to make your own, I’ve heard Monin makes a great lavender syrup.
  • Ice. Helpful to quickly chill the drink and keep it cold until you finish it!

Quick Tips for an Iced Earl Grey Latte

A London fog is typically served warm and made from Earl Grey tea, steamed milk, and vanilla syrup. The iced version is a refreshing way to enjoy a London fog during the warmer months, when sipping at a hot drink may not sound all that appetizing.

The Best Earl Grey Tea for Iced Earl Grey Lattes

There are a ton of varieties of Earl Grey tea out there. My favorites always tend to have vanilla, which I think cuts through some of the acidity in black tea. Here are a list of my favorites, in no particular order, in case you’re looking for a new favorite caffeinated tea:

How to Make an Iced London Fog

For the best flavor, use Earl Grey tea that has had a chance to cool slightly. (The cooler the tea, the less ice it will melt and water down the flavor with.) You can also brew the tea in advance and keep it in the fridge until you’re ready to use the cooled tea in this recipe!

I recommend using a glass that holds 12-16 ounces (350-475 ml). That will give you plenty of room for ice and stirring everything together.

Then, add milk and the lavender syrup, and stir together to combine.

For a lightly sweetened London fog, add one Tablespoon of lavender syrup. For a sweeter London fog, add two Tablespoons of lavender syrup.

The milk will mix fairly easily into the tea, but the lavender syrup tends to sink to the bottom. That’s why I recommend stirring everything together, or at least swirling it around a few times (if you plan to take your drink on the go).

FAQ: Making Iced London Fogs at Home

Common questions when making this recipe:

Can I brew the tea for this iced tea latte in advance?

Absolutely! Brew the tea up to three days in advance and store in the fridge. Then, skip over the first step in the recipe and use 6 ounces (180 ml) of the brewed tea in Step 3.

Can I use plant-based milk in an iced Earl Grey latte?

Yes! Plant-based milk with a higher fat content, like oat milk, will give you a creamier consistency similar to cow’s milk, but you’re welcome to use whatever milk you like.

How much syrup should I add to an iced London fog?

For a lightly sweetened tea latte, use one Tablespoon (equivalent to a little less than one pump). For more sweetness, use two Tablespoons.

Dish Cleanup: Piece of Cake

I rate my recipe cleanups on a scale of 1 to 5. 1 is only a handful of dishes, and 5 is everything including the kitchen sink.

My iced London fog recipe has a cleanup rating of a 1. You’ll have to clean about three glasses/cups and two spoons total if you measure everything rather than just eyeballing it.

Bonus: If you use regular drinkware as opposed to the fancy stuff for photography like I did here, you should be able to throw everything in the dishwasher (if you have one).

Iced London Fog

Two highball glasses filled with ice and Earl grey lattes, topped with lavender sprigs.

A twist on the traditional, this iced London fog recipe uses lavender syrup for a light floral flavor. Substitute your favorite syrup to make this Earl Grey latte your own.

Prep Time 5 minutes
Additional Time 5 minutes
Total Time 10 minutes


  • 1 teaspoon loose leaf Earl Grey tea, or 1 Earl grey tea bag
  • ¾ cup hot water (180 ml)
  • ¼ cup milk (60 ml)
  • 1-2 Tablespoons lavender syrup
  • ½-1 cup ice


  1. Brew the Earl Grey tea in the hot water and steep for five minutes before removing the tea bag.*
  2. Meanwhile, fill a drinking glass with ice.
  3. Pour the tea over the ice. Add milk.
  4. For a lightly sweetened latte, add 1 Tablespoon of lavender syrup. For a sweeter latte, add 2 Tablespoons. Stir together to combine, then enjoy!


*For the strongest Earl Grey flavor, allow the tea to cool an additional 5-10 minutes before pouring it over the ice. This will prevent the ice from melting and watering down the drink too much.

I love using whole milk for the richness, but you can use your favorite kind of milk: 2%, nonfat, oat, almond, etc.

You can also make this iced London fog with honey lavender syrup or vanilla syrup!
