London Fog Latte Recipe & Brewing Kit
Our signature London Fog Latte Kit brings café-quality tea lattes to your kitchen in under five minutes. Each kit includes our premium Earl Grey tea blend with bold bergamot oil, Madagascar vanilla syrup, and a frother for creating that signature silky microfoam crown.
We developed this kit for tea lovers who want barista-level results without the complexity. The Earl Grey base steeps perfectly in hot water while you steam your milk of choice, then the vanilla syrup ties everything together with subtle sweetness that never overpowers the tea’s floral notes.
What’s in your London Fog kit
How to Make a London Fog Latte with Our Kit
Making your first London Fog latte takes just four simple steps. Start by heating 8 ounces of water to 200°F and steeping one tablespoon of our Earl Grey blend in the infuser basket for 4-5 minutes—this extracts the full bergamot complexity without bitterness.
While your tea steeps, heat 4 ounces of milk (dairy or plant-based) to 150°F and use the included frother to create microfoam for 20-30 seconds until you see a silky, paint-like texture. Pour the steeped tea into your favorite mug, add one pump of vanilla syrup, then slowly pour the frothed milk over the back of a spoon to layer that signature cloud-like top. The entire process mirrors the approach we share across our collection of tea latte recipes, where proper steeping time and milk temperature make all the difference.
Earl Grey Tea & Vanilla Syrup Components
We source our Earl Grey blend from Sri Lankan estates known for robust black tea that stands up to milk and flavorings. The bergamot oil comes from Calabrian citrus groves in southern Italy, where the fruit’s aromatic rind produces the most authentic Earl Grey character. This combination creates a tea base that remains present even after you add milk and vanilla.
Our vanilla syrup uses real Madagascar vanilla bean extract suspended in cane sugar and water—no artificial flavoring or corn syrup fillers. The pump bottle dispenses a consistent 0.5-ounce serving, so you can replicate café ratios at home without measuring spoons. One bottle provides enough syrup for the entire 8-ounce tea tin, keeping your ingredient ratio perfectly matched.
Dietary Compatibility & Ingredient Details
Every component in our London Fog kit accommodates diverse dietary needs. The Earl Grey tea contains only black tea leaves and bergamot oil—naturally vegan, gluten-free, and kosher certified. The vanilla syrup contains cane sugar, water, vanilla extract, and citric acid as a preservative, with no animal-derived ingredients or common allergens.
When you supply your own milk, the final latte reflects your dietary choices. We’ve tested the recipe with whole dairy milk, oat milk, almond milk, soy milk, and coconut milk—all produce excellent results with slight texture and flavor variations. Coconut milk adds tropical sweetness that complements the bergamot, while unsweetened almond milk creates a lighter latte that emphasizes the tea’s floral notes.

London Fog Brewing Questions
You can make a basic version with any Earl Grey tea bags, vanilla extract mixed with simple syrup, and a whisk for manual frothing. However, our kit’s bergamot-forward loose-leaf blend and ready-to-use vanilla syrup produce more consistent café-quality results.
The included frother also creates microfoam texture that’s difficult to achieve by hand whisking. If you’re testing the drink before committing to a kit, grocery store ingredients work for trying the flavor profile, but the texture and tea intensity won’t match what this kit produces.
A London Fog made with our Earl Grey blend contains 40-50mg of caffeine per 12-ounce serving, depending on steep time. That’s roughly half the caffeine in a comparable coffee latte, which typically has 75-150mg depending on espresso shots.
This moderate caffeine level provides gentle energy without jitters or afternoon crashes. Many of our customers drink London Fogs later in the day specifically because the lower caffeine content doesn’t interfere with evening sleep the way coffee would.
Whole dairy milk produces the richest, most stable microfoam because its fat and protein content create lasting bubbles. Among plant milks, barista-blend oat milk performs closest to dairy with creamy texture and good foam retention.
Almond milk creates lighter, less stable foam but works well if you prefer the tea flavor to dominate. Soy milk froths moderately well but can curdle if your tea is too hot—let it cool 30 seconds before adding soy milk. Coconut milk adds tropical sweetness but produces thinner foam.
Our Earl Grey maintains peak bergamot intensity for 6-8 months after opening when stored in the airtight tin away from light, heat, and moisture. The black tea base remains safe to drink well beyond that timeframe, but the bergamot oil’s aromatic compounds gradually fade.
You’ll notice the tea losing its signature citrus punch before it becomes stale. For maximum flavor, we recommend finishing the 8-ounce tin within six months, which aligns with making 25-30 lattes—roughly one per week for half a year.
Absolutely. Our standard recipe calls for one pump of vanilla syrup (0.5 oz), but you can start with half a pump or omit it entirely for an unsweetened “dirty” London Fog that emphasizes the Earl Grey’s natural flavor. Some customers add a small splash of pure vanilla extract instead of syrup for vanilla aroma without added sugar.
You can also balance sweetness by using unsweetened plant milk rather than dairy milk, which contains natural lactose sugars. The bergamot oil provides enough flavor complexity that many tea purists prefer minimal or no added sweetness.
Yes, our handheld frother spins at 19,000 RPM, which generates enough turbulence to incorporate air and create microfoam comparable to café steam wands. The key is positioning the whisk just below the milk’s surface during the first 10 seconds to introduce air, then submerging it fully to refine the bubbles into silky texture.
For best results, use cold milk and froth in a container tall enough to accommodate volume expansion—milk roughly doubles in volume during frothing. The dual-coil whisk head moves more liquid than single-coil frothers, reducing frothing time and improving consistency.
Our loose-leaf Earl Grey uses whole-leaf black tea from Sri Lankan estates rather than the fannings and dust typically found in grocery store bags. The larger leaf pieces release flavor more gradually during steeping, creating a smoother, less astringent brew that doesn’t turn bitter with milk added.
We also use natural bergamot oil from Italian citrus rather than synthetic flavoring, which provides authentic Earl Grey character with floral complexity that artificial versions can’t replicate. The oil concentration in our blend is calibrated specifically for lattes—strong enough to remain present after dilution with milk and vanilla.
