A New Take on Earl Grey In barista terms, a London Fog is an earl grey tea latte with vanilla, and our London•Fog Tea Capsules bring this delectable drink to your cup within seconds. This all-in-one capsule combines aromatic and bright earl grey flavor with creamy oat milk, natural flavor and sweeteners to create the perfect frothy London Fog. Our London•Fog is also low in calories and carbs, perfect for indulging in moderation. Sip on its own or indulge with a dollop of whipped cream on top. For a refreshing alternative, pour over ice. Sip your favorite tea lattes without contributing to environmental waste - featuring a commercially compostable capsule body, simply remove the foil lid and save the body for composting.
