Amount of Caffeine Decreases When Milk is Added

Ordering milk with your coffee reduces the amount of caffeine per serving.

The main reason is because the milk takes up space in the cup. As a result, there is less coffee and less caffeine.

Here is a quick list of the amount of caffeine in a hot brewed coffee with whole milk, by size:

Small hot coffee with milk has 165mg of caffeine (15mg less than without milk)
Medium hot coffee with milk has 187mg of caffeine (23mg less than without milk)
Large hot coffee with milk has 240mg of caffeine (30mg less than without milk)

The amounts of caffeine are the same whether you select skim milk, whole milk, or a non-dairy option such as almond milk.

A small iced coffee has 196mg of caffeine, half the amount of caffeine in a large size. Adding a dairy option reduces the caffeine value by approximately 20 milligrams.

Flavored Iced Coffees Have Less Caffeine

If you’re a coffee drinker who enjoys a sweeter cup of coffee, stop by the popular fast food chain and choose from various flavors, including French vanilla, mocha swirl, butter pecan, or caramel swirl.

Adding a flavored syrup decreases the total amount of caffeine in a Dunkin’ iced coffee compared to a standard unflavored drink.

Here is a quick summary of the caffeine content, based on a size medium:

Dunkin’ original iced coffee has 294mg of caffeine
Dunkin’ Mocha iced coffee has 289mg of caffeine
