Coffee producers such as Starbucks and certain specialty roasters use innovative and propriety processes to manufacture premium-quality instant coffee. However, if you choose a freeze-dried, chemical-free instant coffee, you will usually find a better quality. There is no doubt that the processes of decaffeination and dehydration negatively affect the coffee’s flavor.
Conclusion On Choosing The Best Instant Decaf Coffee If you would like to know more about how manufacturers create instant coffee, look at our article on the process. However, it takes more time than spray drying and is more complex and costly. Because heat is not used with freeze-drying, the flavor and aroma of the coffee stays intact. This process leads to the ice sublimating and coffee granules remaining. At this point, the manufacturer breaks the ice and dries it using pressure under a vacuum at a low temperature. However, spray drying is a cheap and speedy method allowing for the production of huge batches of instant coffee at a time.įreeze Drying: In this method, the coffee is frozen. The extreme temperature removes much of the flavor and aroma of the coffee, which is not ideal. This evaporates the water leaving the dry coffee powder to accumulate on the floor of the tower. Spray Drying: This involves spraying coffee into a giant tower of very hot air. There are two primary means of dehydrating the coffee extract. Then, the coffee makers remove the water, so the extract becomes instant coffee. The manufacturers take the decaffeinated, roasted beans and grind then brew them into a coffee extract. However, because these beans are destined to become instant coffee, the roasted beans need to be transformed into coffee powder.
Once the caffeine is removed from the green beans, the beans have to be roasted. Read Also: Best Coffee Beans To Buy – A guide for choosing the right coffee for you. However, it is less commonly used in instant decaf coffee. We have previously examined the best decaf coffee beans, and the majority of the brands use the Swiss Water Process. Brands that use this product will invariably promote their decaf beans with this as a selling point. The Swiss Water Process is chemical-free and removes 99% of the caffeine. However, it is more expensive and complex. This method only uses water to remove the caffeine. Higher-end companies will often employ the Swiss Water Process. However, generally, the idea of using chemical solvents is frowned upon by the consumer. Some manufacturers dissolve the caffeine using “supercritical” carbon dioxide, which is CO2 used at very high pressure. However, with regulatory approval, the assumption is that the method is safe. This has led to concerns that the solvents may be toxic. The most cost-effective method is to extract the caffeine from the water using chemical solvents, including ethyl acetate and methylene chloride. Because of this, the flavor of decaf coffee has a poor reputation. The tricky part comes in extracting the caffeine while retaining the taste. Therefore, for people more sensitive to the effects of caffeine, decaf options are a good choice. However, certain techniques can extract between 97% and 99% of the content. How Caffeine Removal Takes PlaceĪll coffee beans contain caffeine. However, in the meantime, we can look at what is available and judge which are the options for better tasting instant decaf coffee. One day, there may be methods of removing caffeine and making instant coffee that retain the perfect aromas and flavors. However, that doesn’t mean there aren’t some options on the market that are worth trying. Decaffeination and dehydration will always have a detrimental effect on the finished product’s flavor and aroma. There’s no doubt in our minds that instant and decaf coffee can’t reach the same quality as freshly brewed, caffeinated coffee.
