The Vancouver Origin Archive: Where the London Fog Began
Baristas in Vancouver, Canada, created the London Fog in the 1990s. Many sources credit Mary Loria, who requested a customized Earl Grey tea latte during pregnancy. Despite its name, the drink did not originate in London. The name reflects its misty, cloud-like appearance rather than its geography.
This origin story corrects a common myth and strengthens the drink’s authenticity.
