Decaf coffee refers to any coffee in bean, ground or in prepared form that has most of the caffeine removed from it via a variety of decaffeination processes. These processes do not make decaf coffee caffeine free, but they significantly reduce caffeine amounts in the average cup of joe. Some people choose decaffeinated coffee to avoid most caffeine as per dietary recommendations, to lower jittery response, or simply out of personal preference.
The first decaf coffee styles were made in the early 20th century. The earliest methods of decaffeination soaked green coffee beans in a benzene solution, which helped remove the caffeine. This process was one of the most popular for many years, and in the US, people may recall that the Sanka® brand was made in this manner. The chemicals used were not particularly healthy though, and ultimately other processes replaced the benzene soak method.
These additional methods included using other chemicals to treat beans and remove caffeine. Alternately, repeatedly soaking coffee beans in water, called the Swiss Water Method, became an especially popular means to create decaf coffee. This method is actually nearly as old as the benzene solution treatment, and was developed in the first third of the 20th century. Today, many people prefer water methods of decaffeination since they skip the addition of chemicals and are thought purer.
For coffee purists, it may be hard to get a cup of coffee that truly tastes good and has been subject to any chemical treatment. This is a matter that is still under development, but some people argue decaf coffee tastes different. There have been some discoveries in this area that might ultimately benefit those who have a discriminating palate when it comes to coffee. For some time, people have been discussing a coffee bean that was discovered in Africa and that is caffeine free. It is being grown and developed to try to make a superior and good tasting bean for fully naturally decaffeinated coffee.
While people wait for this development, several other things ought to be noted about decaf coffee. Most important of these is that decaf really doesn’t mean uncaffeinated. Depending on degree of caffeine left, approximately five to ten cups of decaf is roughly equivalent to the average cup of caffeinated coffee. People who really need to eliminate caffeine completely, especially for medical reasons, should not see decaf coffee as a viable substitute unless a doctor approves this.
On the other hand, those who merely need to cut down can find good tasting decaf, especially where finer coffees are sold. There are continued efforts to refine decaffeination processes, and many gourmet coffee companies are sensitive to people’s desires to avoid extra chemicals. They have continued to remove caffeine from beans via the water method, or with chemical applications that are naturally derived from common foods.
