In a medium London Fog, how many ounces of hot water are used?

In preparing a medium London Fog, the typical volume of hot water used is 12 ounces. This amount serves as the base of the drink, which is a tea-based beverage typically made using Earl Grey tea, hot water, steamed milk, and vanilla syrup. The 12 ounces provides a balanced dilution and ensures that the flavors meld well without overpowering the taste of the tea or the creaminess from the milk. Using this specific measure aligns with standard practices in beverage preparation, ensuring a consistent and enjoyable experience for those who order it.

While other amounts might be plausible for different drink sizes or variations, the 12-ounce measurement is standard for a medium size, fitting well within the overall volume of the drink when considering the additional ingredients.
