How Much Caffeine Is in Decaf Coffee Compared to Other Drinks?

March 31, 2026

Cutting back on caffeine? Knowing approximately how much is in your favorite drinks is a good place to start. How do popular coffee drinks, including decaf, actually compare to other drink options like black tea, matcha, or cola? The answer might surprise you.

Caffeine Content Compared Across Popular Beverages

Caffeine content can vary based on preparation method, and other factors like brewing time, product brand, and serving size. So, it is important to note that all values are approximate. To estimate how many decaf coffees equal the caffeine in other beverages, an average caffeine value was used rather than a range. Data sourced from the FDA, Health Canada, and Mayo Clinic, linked below.

Regular Coffee vs. Decaf Coffee: How Do They Compare?

Drip coffee, also known as filter brew, is the coffee standard most people think of, averaging 95–135 mg of caffeine per 8 oz. cup. By comparison, a standard 8 oz cup of decaffeinated drip coffee contains roughly 2–15 mg of caffeine, depending on the bean, roast, and brewing method.

The caffeine levels of espresso-based drinks like lattes and cappuccinos depend on how many shots are used. A single 1 oz. espresso shot contains roughly 63 mg of caffeine. A two-shot latte contains about 126 mg, which is more than a standard cup of drip coffee. Decaf espresso contains about 5 mg of caffeine per 1 oz. shot, so a decaf latte made with Swiss Water® Process coffee contains approximately 92% less caffeine than its regular counterpart, while still delivering the same depth and flavor that good espresso should always convey.

Cold brew is often the biggest surprise to people. Because the grounds steep for 12–24 hours, the extraction results in significantly higher caffeine content. Cold brew often delivers 100–200 mg of caffeine per 8 oz. serving. Decaf cold brew has an approximate range of 5–25 mg, depending on the brand and product concentration.


Caffeine Content Comparison Chart
Beverage	Serving Size	Caffeine (mg)*	Approx. Cups of Decaf*	Caffeine Level
Decaf Coffee
Decaf espresso (single shot)	1 oz	~5 mg	-	Very Low
Decaf drip coffee	8 oz	2-15 mg	-	Very Low
Coffee
Espresso (single shot)	1 oz	47-75 mg	approx. 12 cups	Medium-High
Latte (single shot)	8 oz	47-75 mg	approx. 13 cups	Medium-High
Drip coffee	8 oz	95-135 mg	approx. 23 cups	High
Cold brew	8 oz	100-200 mg	approx. 30 cups	Very High
Tea
Green tea	8 oz	29-37 mg	approx. 7 cups	Low
Black tea	8 oz	30-71 mg	approx. 10 cups	Low-Medium
Matcha (1 tsp powder)	8 oz	40-70 mg	approx. 11 cups	Medium
Soft Drinks
Cola	12 oz	34-46 mg	approx. 8 cups	Low-Medium
Diet Cola	12 oz	39-50 mg	approx. 9 cups	Medium
Mt. Dew	12 oz	54 mg	approx. 11 cups	Medium

Tea and Other Drinks: Where They Rank For Caffeine

Green tea and black tea both contain less caffeine than a standard cup of coffee, but more than decaf. Green tea averages 29–37 mg per 8 oz. cup. Black tea runs slightly higher at 30–71 mg.

Matcha, which is a powdered form of green tea, deserves its own mention. It has become a popular coffee alternative, particularly for people looking for a smoother energy experience or who enjoy milky drinks. A typical matcha serving, about 1 teaspoon (2 grams) of powder, delivers 40–70 mg of caffeine. Matcha also contains L-theanine, an amino acid associated with calm, sustained alertness. That said, matcha is not a low-caffeine option. Depending on the powder and preparation, it delivers as much caffeine as a shot of espresso.

Cola and diet cola contain 34–50 mg of caffeine per 12 oz. can. Mountain Dew contains 54 mg per 12 oz. can. Both are lower-caf than most coffee drinks, but still well above decaf.

What "Decaf" Actually Means

Decaf coffee is not completely caffeine-free. In the United States, FDA standards require at least 97% caffeine removal, leaving a small but measurable amount in every cup. Regulatory definitions vary by country, and most produce similar results for consumers. The exceptions are worth knowing.

For the United States:

The US Food and Drug Administration says that at least 97% of the caffeine must be removed during processing for decaf to be labeled as decaf
The regulation focuses on the percentage of caffeine removed before roasting
This leaves small amounts of caffeine in the finished coffee

For Canada:

Health Canada limits the amount of caffeine allowed in the finished coffee
Roasted decaf: no more than 0.1 percent caffeine by weight
Instant decaf: no more than 0.3 percent caffeine by weight

For Europe, South Korea, and Japan:

The EU sets the same 0.1% residual caffeine limit as Canada for roasted coffee, established under EU Directive 1999/4/EC.
South Korea is implementing the same 0.1% threshold under a new MFDS regulation effective in 2026.
Japan's standard is set by the AJCFT, a self-regulatory industry body rather than a government agency, and requires only 90% removal of caffeine. A product labeled decaf in Japan could contain up to twice the caffeine level required by US or EU standards.

How the results compare:

The terms "97% removed" and "0.1% remaining" measure caffeine differently but produce similar results in the cup. Across the US, Canada, the EU, and South Korea, consumers can expect decaf to contain roughly the same trace amounts. Japan is an exception worth knowing, with its larger caffeine allowance.

The Swiss Water® Process is a trusted method for removing caffeine from unroasted coffee beans. It uses water, not chemical solvents, as in some other methods, to extract caffeine while preserving the bean's original flavor and origin characteristics. For people who want to minimize chemical exposure or residual solvent flavors while still enjoying great-tasting coffee, Swiss Water Process decaf is worth knowing about and seeking out.

Choosing a Lower-Caffeine Option

If you're watching your caffeine intake for any reason, here's a practical way to use the chart above:

Lowest caffeine: Decaf coffee in any preparation (2-25 mg per serving)
Low caffeine: Green tea (29-37 mg), cola (34-46 mg)
Moderate caffeine: Black tea (30-71 mg), matcha (40-70 mg), espresso (63 mg)
Higher caffeine: Drip coffee (95-135 mg), cold brew (100-200 mg)

Both the FDA and Health Canada advise a daily caffeine limit of 400 mg for most healthy adults. Health Canada advises pregnant individuals, those planning to become pregnant, and those who are breastfeeding to limit intake to 300 mg per day. Speak with a healthcare provider to determine what is appropriate for your situation.

If you have questions about caffeine sensitivity or how caffeine may interact with other health conditions or medications, it's always recommended to talk with your doctor.

3 Key Takeaways

Decaf coffee contains roughly 2–15 mg of caffeine per 8 oz. serving. That's significantly less than green tea, black tea, matcha, cola, and all regular coffee drinks.
Cold brew has some of the highest caffeine levels of any coffee drink, often double that of standard drip coffee, making decaf cold brew a better option for people managing their intake.
The Swiss Water® Process removes caffeine from unroasted coffee beans using water, time, and temperature rather than chemical solvents, preserving the coffee's origin flavor.
