You wouldn’t necessarily associate Pepsi with having caffeine in at all. 

However, alongside its main competitor, Pepsi does contain this stimulant that is usually associated with tea or coffee. 

To be exact Pepsi contains 35.34mg of caffeine in your typical 330ml can. Checkout our breakdown of sizes below.

Why Trust Me?

I’m Tom and I have been working in the coffee industry for over 10 years, starting my journey as a barista in Australia, working on coffee farms in South America and roasting coffee in The UK. I am the founder of Batch Coffee Club (a UK Coffee Subscription), which showcases the very best coffee from around the world.

Does Pepsi have Caffeine in?

Yes, pepsi contains caffeine.

To be exact, a 330ml can of Pepsi contains 35.34mg of caffeine.

To put this into perspective, the amount of caffeine in a black filter style coffee of this size is roughly 138mg*.

But you should also take into account that a serving of Pepsi is usually much bigger than a serving of coffee, so you may actually consume more caffeine when enjoying your post burger Pepsi.

*This number can vary widely in coffee because of the many factors when it comes to brewing like the particular type of coffee, the roast level of the coffee beans or the brew guide.

Will Pepsi stop me from sleeping?

Yes, Pepsi can stop people from sleeping.

Although Pepsi does contain caffeine as we have discussed, it also contains sugars that may factor into stopping you from sleeping.

This is not to say that Pepsi will stop you from sleeping as each person is different and caffeine and sugars have different effects on everyone.

I would recommend, if you are struggling to sleep after consuming Pepsi drinking your last can as long before going to bed as possible and maybe save Pepsi for a lunch time beverage.

Caffeine stays in your system for many hours and if you have a fairly low tolerance then this may significantly affect you.

Pepsi vs Coffee

So pound for pound there is more caffeine in coffee, however because of the different levels of caffeine in coffee you may be surprised at how close the caffeine content becomes.

On top of this, a typical serving of Pepsi is much bigger than that of coffee so actually there may be more caffeine in Pepsi than coffee after all.
