What is Decaf Coffee, How It's Made, and Its Differences from Regular Coffee - Benefits of Low-Caffeine Beans

Last Updated: 2026/01/27, Decaf coffee is rarely found in specialty coffee shops. Whether for pour-over or espresso, decaf coffee beans are quite uncommon. Why is this? Coffee flavor is our standard for measuring the quality of coffee beans. Decaf coffee loses some flavor during the decaffeination process, so it should theoretically be lower in price. However, decaf coffee also involves additional decaffeination costs, which tends to increase the final price.

Decaffeinated coffee is rarely found in specialty coffee shops, whether for pour-over or espresso. Decaf coffee beans are quite uncommon. Why is this? Coffee flavor is our standard for measuring the quality of coffee beans. During the decaffeination process, decaf coffee loses some of its flavor, so it "should" be priced lower. However, decaf coffee also has the cost of decaffeination involved, which relatively increases the price. This is why many specialty coffees do not undergo decaffeination processing—because it loses flavor and makes consumers feel that the cost-performance ratio is not as high. Of course, there is a coffee variety called Laurina, which is naturally low in caffeine, although it doesn't retain only 0.1% caffeine.

Many people enjoy drinking coffee, but sometimes excessive caffeine intake can cause symptoms like heart palpitations. For these people, decaffeinated coffee is an excellent choice.

Decaf coffee is just like regular coffee, just with reduced caffeine content.

FrontStreet Coffee will provide a detailed introduction to decaffeinated coffee and its health effects in this article.

What is Decaffeinated Coffee and How is it Made?

Decaf is short for decaffeinated coffee. Decaf coffee has had at least 97% of its caffeine removed. There are many methods of decaffeination, most of which involve water, organic solvents, or carbon dioxide. Coffee beans are washed in solvents until caffeine is extracted from them, and then the solvents are removed. Carbon dioxide or charcoal filters can also be used to remove caffeine—this method is known as the Swiss Water Process. This happens before the coffee beans are roasted and ground. Aside from caffeine content, the nutritional value of decaffeinated coffee should be almost identical to regular coffee. However, the taste and aroma may become milder, and the color might change depending on the method used. For those sensitive to the bitterness and aroma of regular coffee, decaf coffee will be more enjoyable.

How Much Caffeine is in Decaf Coffee?

Decaffeinated coffee is not completely caffeine-free. It actually contains varying amounts of caffeine, typically about 3 mg per cup. One study found that each 6-ounce (180 ml) cup of decaf coffee contains 0-7 mg of caffeine. On the other hand, a cup of regular coffee contains an average of about 70-140 mg of caffeine, depending on the coffee type, preparation method, and cup size. Therefore, even though decaf is not completely caffeine-free, the caffeine content is usually very minimal.

In summary: Decaf coffee is not caffeine-free, as each cup contains about 0-7 mg. However, this is much lower than the content in regular coffee.

Decaf Coffee is Rich in Antioxidants and Contains Nutrients

Coffee is actually the largest source of antioxidants in the Western diet. Decaf typically contains similar amounts of antioxidants as regular coffee.

Decaf coffee has the following benefits:

  • Preventing type 2 diabetes, improving liver function, and reducing premature death
  • Preventing aging and neurodegenerative diseases
  • Reducing symptoms of heartburn and lowering the risk of rectal cancer

Coffee may be known for its stimulating effects. It can increase alertness and reduce fatigue. These effects are directly related to caffeine, a natural stimulant present in coffee. Some beneficial effects of regular coffee are directly attributed to caffeine, so decaf coffee should not have these effects.

Here are some benefits that may apply only to regular coffee rather than decaf coffee:

  • Improving mood, reaction time, memory, and mental function
  • Increasing metabolic rate and fat burning
  • Enhancing athletic performance
  • Reducing the risk of mild depression and suicidal thoughts in women
  • Significantly reducing the risk of cirrhosis or end-stage liver damage

When it comes to caffeine tolerance, there are many individual differences. For some people, one cup of coffee might be excessive, while others might handle more. Although individual tolerance may vary, healthy adults should avoid consuming more than 400 mg of caffeine per day. This is equivalent to about four cups of coffee. Increased consumption can lead to elevated blood pressure and insufficient sleep, thereby increasing the risk of heart disease and stroke. Excessive caffeine can also overwhelm the central nervous system, causing irritability, anxiety, digestive problems, heart arrhythmias, or difficulty sleeping in sensitive individuals. People who are very sensitive to caffeine may want to limit their regular coffee intake or switch to decaf or tea. People with certain medical conditions may also need to limit their caffeine intake. This includes people taking prescription medications that can interact with caffeine. Additionally, pregnant and breastfeeding women are advised to limit their caffeine intake. Children, adolescents, and people diagnosed with anxiety disorders or sleep difficulties are also recommended to reduce or avoid caffeine consumption.
