How Much Caffeine Is In A Latte: Understanding the Buzz?

For many of us, waking up and starting the day isn’t quite right without our caffeine fix. And for coffee lovers, there’s nothing quite like the taste and warmth of a latte to jumpstart your day. 

But just how much caffeine is in that cup of frothy goodness? On average, a single shot of espresso contains around 63 mg of caffeine. Therefore, a 16-ounce latte, typically made with a double shot of espresso, contains approximately 130 mg of caffeine.

In this blog post, we’ll dive deep into lattes and caffeine and explore some factors that impact caffeine content so you can better understand the buzz.

How Much Caffeine Is In A Latte

What is a latte?

Before diving into caffeine content, let’s start with understanding a latte. It’s made with espresso, steamed milk, and a touch of foam. 

Depending on where you get your latte from, it can come in varying sizes, but the most common is 12 ounces. 

The standard recipe is 1-2 shots of espresso and then steamed milk added to fill the cup, with a small amount of foam at the top. The caffeine content will increase proportionally if you order a latte with extra espresso.

The impact of espresso shots

The number of espresso shots in a latte can significantly impact how much caffeine is in the drink. The standard recipe includes one to two espresso shots containing approximately 63 mg of caffeine per shot. 

So, twelve ounces of latte with one shot of espresso would contain around 63 mg of caffeine, but if you add an extra shot, the caffeine content would double to about 126 mg.

Milk and Foam

Steamed milk and foam in a latte account for most of the drink’s volume. So when you add milk, you dilute some of the espresso’s caffeine. 

However, the amount of caffeine lost in the process is difficult to determine since it depends on the type of milk used and how much foam is added. Whole milk was the standard in creating the latte. 

With whole milk, the caffeine content per ounce of latte decreases significantly. However, if you use a milk alternative such as almond, soy, or oat, the caffeine content will change since it also contains caffeine.

Coffee shop variations

Understanding that this varies depending on where you get your latte is crucial. For example, Starbucks typically uses a shot pull with less caffeine than other coffee shops. 

On the other hand, different coffee shops have their standard espresso shots and milk steaming processes, so the caffeine contents may also differ. It’s best to look up the nutrition information the shop provides for a specific measurement to help you calculate the caffeine content.

Can I reduce the caffeine in my latte?

If you’re looking to reduce your caffeine intake, there are several ways to do so. 

  • Firstly, you can opt for a smaller latte, which inherently contains less caffeine. 
  • Secondly, you can request that your barista use decaf espresso rather than regular espresso in your drink, which will significantly reduce the overall caffeine content.
  • Finally, you can ask for your latte to be made with fewer espresso shots or with more milk, which will dilute the caffeine content.

Are there any hidden sources of caffeine in a latte?

While espresso shots are the primary source of caffeine in a latte, there may also be small amounts of caffeine in the milk used, particularly if you’re consuming a non-dairy milk alternative that contains caffeine. 

Some flavored syrups may contain small amounts of caffeine, so it’s worth checking the ingredient list if you’re trying to avoid caffeine altogether.

How does the roast level of coffee affect the caffeine content in a latte?

The roast level of the coffee used can affect the overall caffeine content in your latte. Darker roast coffees tend to contain less caffeine than lighter roast coffees, so if you’re concerned about your caffeine intake, opt for a lighter roast coffee when ordering your latte.

How long does the caffeine in a latte stay in my system?

Caffeine can take several hours to metabolize in the body fully, so you may still feel the effects of your latte several hours after consuming it. 

However, most people find that the effects of caffeine wear off after a few hours and that they can sleep normally even after drinking a latte in the afternoon.

While the amount of caffeine in a latte can vary greatly depending on several factors, lattes provide a moderate caffeine boost for most consumers. 

Suppose you’re concerned about your caffeine intake. In that case, there are several ways to reduce the amount of caffeine in your latte, including opting for decaf espresso, requesting a smaller-sized drink, or diluting your drink with more milk. 

Ultimately, the best way to regulate your caffeine intake is to be mindful of your consumption and make informed choices about the drinks you enjoy.


So there you have it, the world of lattes and caffeine content revealed. The caffeine content is affected by different factors, including the number of espresso shots, steamed milk, and foam. Each of which impacts the overall caffeine count in your latte. 

Please remember that caffeine sensitivity differs from individual to individual; what may not satisfy you may provide a much-needed boost for someone else. 

It’s always good to double-check the caffeine content when you’re on the go to ensure you get the right amount of caffeine to power your day.
