London Fog (also known as Vanilla Tea Misto or an Earl Grey Tea Latte, and in Scotland it is known as a Vancouver Fog) is the name of a drink which originated in Vancouver, British Columbia, Canada, although the creator remains unknown, among several claims. One such claim is from the Island Coffeehouse in Langley, Washington, a non-profit student run organization, where it was originally made with Peppermint Tea in 2006. However, patrons of Starbucks in Calgary, Alberta have asked for this decadent drink since the winter of 2004. It is common in Washington and Oregon, as well as in BC's lower mainland and throughout British Columbia and Alberta. Canadian Second Cup cafés also carry the drink.
The "London Fog" was recently the subject of an investigation on the Canadian Broadcasting Corporation's afternoon show Freestyle.

Notes, tips and variations 
- San Francisco Fog - In a punch bowl place 2 quarts cold black coffee and 1 bottle (750ml) brandy. Float one quart of vanilla ice cream (cube shaped ice-cream looks best). Facilitate ice cream to melt by spooning liquid over it and watching it turn into a delicious "fog." (Created by E. Ralph DeGeer)

- Oxford Haze - substitute English Breakfast and Hazelnut syrup - first served at Shatterbox Coffee Bar in Victoria, BC in January 2013
The method used at Shatterbox is this: In a 12oz. cup place tea bag, 2/3oz hazelnut syrup and top with 2oz near boiling water. Let steep, swirling occasionally, while steaming milk. Milk should be brought to just over 140 degrees F (60C) and poured directly over the steeping tea mixture until the cup is full. Enjoy!
