How do decaf and regular arabica beans compare?

Decaf coffee is generally regarded as safe, and it starts from arabica beans, which naturally hold about 0.9 to 1.4 percent caffeine by weight. Processed decaf must fall below 0.1 percent caffeine in the EU and below 3 percent of the original content under FDA rules. Flavor does shift, but careful brewing keeps the cup drinkable.

Robusta, at 1.8 to 4 percent caffeine, rarely appears in specialty coffee because of its harsher flavor. Decaf splits into naturally low-caffeine types and artificially decaffeinated beans. A Colombian Huila decaf from Front Street illustrates the point: origin grade, processing method, and brewing parameters all shape the nutritional value of coffee and the final taste.

Decaf coffee has attracted increasing attention in recent years, yet many coffee enthusiasts still have questions about it: How exactly is decaf coffee decaffeinated? Is drinking decaf coffee healthy? Will its flavor be greatly compromised? From the professional perspective of Front Street Coffee (FrontStreet Coffee), this article systematically sorts out the definition of decaf coffee and the mainstream decaffeination methods, and uses Front Street's decaf coffee beans from Colombia's Huila region as an example to analyze their regional grade, processing method, and brewing parameters. At the same time, the article also responds to the common concern of "whether decaf coffee is healthy," and includes a segmented brewing plan shared by Front Street Coffee to help coffee lovers fully understand the true nature of decaf coffee.

Friends familiar with specialty coffee know clearly that the beans selected for specialty coffee are basically all from the Arabica variety. Compared with Robusta, Arabica has a lower caffeine content, so its performance in cupping is usually better. Robusta beans, because of their higher caffeine content, inferior flavor, and even the possibility that excessive drinking may be harmful to health, rarely appear within the scope of specialty coffee. However, there is now also a popular type of decaf coffee bean on the market whose caffeine content is even lower than Arabica. So, is drinking decaf coffee healthy? What advantages and disadvantages does it have? Next, Front Street Coffee (FrontStreet Coffee) will answer these one by one for coffee lovers.

What is decaf coffee?

Usually, the caffeine content of coffee beans is measured as a proportion of weight. The caffeine content of Arabica coffee beans is between 0.9%-1.4% (about 1.2% on average), while Robusta is 1.8%-4% (about 2.2% on average). Decaf coffee can be divided into two categories: naturally low-caffeine coffee and artificially decaffeinated (decaf) coffee. The European Union's standard for artificially processed decaf coffee is: after processing, the caffeine content does not exceed 0.1% of the green beans; while the U.S. Food and Drug Administration FDA standard is to remove it to below 3% of the original caffeine content.

For example, Front Street Coffee (FrontStreet Coffee) currently has a decaf coffee bean from Colombia's Huila region, and its flavor is quite good.

Does decaf coffee taste good?

This Colombian decaf coffee bean from Front Street Coffee (FrontStreet Coffee) comes from Huila, Colombia's most famous and highest-altitude coffee-producing region. The coffee beans produced in this area belong to the specially selected high-mountain coffee beans of the Colombian national company, and are known as a Colombian national treasure. Therefore, this decaf coffee bean from Huila is destined not to have too poor a flavor. After all, the quality of a coffee bean's flavor depends on its region, variety, and processing method, and even beans from the same region need to be graded again. As long as high-quality coffee beans have gone through layer upon layer of selection, how could their flavor be poor? If you drink one that tastes bad, then it must also be that this bean itself did not taste good, and you cannot blame the entire coffee category for not tasting good. If you drink one that tastes bad, then you must not have drunk it the right way.

Therefore, Front Street Coffee (FrontStreetCoffee) believes that decaf coffee not tasting good is not caused by the processing. Because most decaf coffee uses cheap, commercial-grade coffee beans in its raw material selection. Modern decaffeination technology is quite complex, and in most cases, companies producing decaf coffee tend to favor varieties with high caffeine content when selecting materials (such as Robusta beans). Before decaf coffee beans undergo decaffeination, the coffee beans themselves are already not tasty. Like other coffee beans sold in coffee shops, if decaf coffee beans use high-quality Arabica beans from the green bean stage, then even after decaffeination, decaf coffee can still perform very well.

In addition, the batch of Colombian decaf green beans selected by Front Street Coffee (FrontStreet Coffee) is graded Supremo. In Colombia's coffee bean system, Supremo is the highest grade, so the quality is naturally very guaranteed.

Colombian decaf coffee processing method

There are four decaffeination methods: the direct/indirect solvent process, the supercritical carbon dioxide process, the Swiss Water Process, and the mountain spring water process, and the common ones are the direct solvent process and the Swiss Water Process. As mentioned above by Front Street Coffee (FrontStreet Coffee), this Colombian Huila decaf coffee bean uses the Swiss Water Process.

Swiss Water Process

The procedure of this processing method is: first soak the green coffee beans in hot water, and the soaking stage has actually already partially removed the caffeine. Then filter the soaked solution with activated carbon, and finally pour the solution back into the coffee beans. This series of steps can remove caffeine more effectively. In addition to not requiring chemical solvents, the soaked solution can also be reused in processing procedures for different batches. The only shortcoming is that the coffee will lose flavor during the filtration process.

However, the caffeine removal rate of this method can reach 99.9%, and it is also the method with the highest caffeine removal rate. Although the Swiss Water Process will lose some coffee flavor, because of its low cost, ease of operation, and high efficiency, the decaf coffee beans we see now are mainly processed by the Swiss Water Process.

Is drinking decaf coffee healthy?

Next is that many people believe drinking decaf coffee is unhealthy, so what is the truth?

As Front Street Coffee (FrontStreetCoffee) said above, decaf coffee, Decaf, is the abbreviation of decaffeinated coffee. There are many methods to remove caffeine from coffee beans. Apart from caffeine content, the nutritional value of decaffeinated coffee should be almost the same as regular coffee. However, depending on the method used, the taste and smell may become slightly milder, and the color may change. This can make decaffeinated coffee more pleasant to those who are sensitive to the bitterness and smell of regular coffee.

So does decaf coffee bean mean it is completely caffeine-free? Not at all. Decaf coffee actually only removes about 97% of the caffeine, not completely. Although caffeine still exists, compared with regular espresso, the caffeine in decaf coffee will not have any effect on the vast majority of people.

So as long as it is consumed normally and within the amount the body can accept in a day, it will not cause harm to the body. But if you drink it without restraint and exceed the amount of caffeine the human body can absorb in a day, then it will naturally also cause harm to the body.

The above is the relevant knowledge about decaf coffee compiled by Front Street Coffee (FrontStreetCoffee). I hope it can help coffee lover friends better understand knowledge about decaf coffee. Next, Front Street Coffee (FrontStreetCoffee) will share how to brew decaf coffee.

How does Front Street Coffee (FrontStreet Coffee) brew decaf coffee beans?

After decaf coffee beans release caffeine through soaking, the fiber structure of the beans differs from that of regular coffee beans. Their strong water absorbency slows down the extraction speed, so adjustments need to be made to the brewing parameters.

Dripper: Kono dripper Water temperature: 88.8℃ Coffee dose: 15g Coffee-to-water ratio: 1:15 Grind size: Coarse grind / yellow granulated sugar coarseness (70% passing rate on China standard No. 20 sieve)

Front Street segmented brewing: Pour in the coffee grounds, add 2 times the water amount (30ml) and bloom for 30 seconds. Then perform the second pour, gently pouring 150ml of hot water in circles, pushing the coffee bed higher so that a golden foam surface forms on top. Wait for the water level of the coffee bed to drop slightly, then pour the final 45ml. After all the coffee liquid has flowed into the server, remove the dripper and end extraction. The extraction time is 2 minutes 10 seconds.

Brewed flavor of Colombian decaf coffee beans: Dark chocolate, caramel, nuts, full-bodied.
