Why Does Decaf Coffee Taste Bad? - Facts You Should Know

Being a regular consumer of decaf coffee, you will know the sole purpose of such a drink is to cut the caffeine content short. Roughly speaking, these drinks will deliver a maximum of one-third content compared to the regular shots.

To meet the expected results, the beans should go through a decaffeination process that will also affect the taste of the coffee. However, certain other factors also contribute to a different taste of decaf drinks. Here are the most prominent causes for it.

Coffee Beans Quality

1- Coffee Beans Quality: Different coffee beans are used to prepare coffee. So, the beans used in the decaffeination process also affect the overall flavor. Arabica, Robusta, and Liberica are the most common types used for this purpose.

Of these three types, the Arabica beans are the most commonly used and the best options for decaf capsules. If you carry out the whole process at home, you know what bean type you have used.

But when you buy decaffeinated pods from the market, you are not sure about the beans used. So, this can be a reason for the bad-tasting decaf coffee.

The Decaffeination Process

2- The Decaffeination Process: As the name 'Decaf' suggests, there must be a procedure for extracting the caffeine to lower the overall content of the coffee beans. Different companies use different methods for this process. Direct and indirect processes, the swiss water method, and the CO2 process are the most popular ones on the market.

Of these three methods, the Swiss Water method is the most reliable and the most effective one. The basic reason for its immense popularity is that it has the least effect on the overall taste of the resulting coffee beans.

It means that the decaf coffee resulting from the Swiss Water process will not have such a bad flavor. If you bought the decaf pods from the market and found them odd tasting, there are possibilities that the company has used some other decaffeination method. It is another major reason for a completely different-tasting coffee.

The Grinding Process

3- The Grinding Process: If you know the overall decaffeination procedure, you'll know that it includes soaking the beans in water, drying, and processing them for the final grounding. Through the process, beans become so dry that they will grind finer than the normal ones.

It means that the dried decaf coffee beans will need a relatively gentle grinding process than used in general. A severe process means a sour-flavored coffee. When you commit any mistake through this procedure, your drink will taste odd.

If you purchased the decaf capsules from the market but found them sour, the company must have ground the beans to an extremely fine level. It is another major reason for the bad-tasting decaffeinated coffee drinks.

Faulty Storage of the Beans

4- Faulty Storage of the Beans: Being an amateur coffee lover, you may know that the coffee beans' storage impacts the drink's overall flavor profile. Here you may think, 'what is the best way to store the beans?'. A short answer is that a dry and cool place is ideal for their storage.

Moreover, the beans must be packed in an airtight container as their exposure to oxygen will ruin the overall taste. If your decaf coffee has a coarse taste, you may not have stored them properly.

As the decaffeinated beans are drier than the normal ones, their reaction with the oxygen will also be faster than the regular beans. So, a slight air exposure will make them taste sour.

Different Taste Buds

5- Different Taste Buds: Sudden shifting from regular to decaf coffee is a major reason for the bad taste. Scientifically, taste buds need some time to get used to the new flavors. So, when you suddenly taste decaf coffee, it may feel odd.

If you have checked the rest of the reasons and found nothing in your case, the decaf coffee will seem odd just due to your taste buds. Gradually, you'll get used to the new flavor, and all will be okay.
