Now that we 8767 ve got a basic framework to work with let 8767 s have a closer look at the before mentioned methods. Since 75% of all coffee is decaffeinated with the help of solvents, I 8767 ll start with solvent based processes.

The Green Bean House was founded to provide all NZ coffee lovers with the means to produce their own perfect coffee. We believe that the journey to the perfect coffee doesn't end with a great grinder and espresso machine. Coffee lovers can take it one step further and roast their own coffee to their personal taste using just a simple frying pan.

In the direct method caffeine is removed by soaking the materials directly in a solvent the solvent is directly applied to the beans. On the other hand, in the indirect method the caffeine-laden water is transferred to a separate tank and treated with a solvent in this case the solvent never touches the beans.

The water is then separated and transferred to another tank where the beans are washed for about 65 hours with either methylene chloride or ethyl acetate. The molecules of the chemical solvent selectively bond with the molecules of caffeine and the resulting mixture is then heated to evaporate the solvent and caffeine.
Let 8767 s begin by stating the obvious. Caffeine occurs in coffee naturally, so any method of decaffeination (no matter how good it is) is considered by many aficionados unnatural. Some go even so far as claiming that it goes against the natural order of things
The way that coffee cherries are handled after they are picked makes a difference in the way that coffee will taste. In Africa and other places around the world, the peaberries are laid on raised beds where they are left to dry in their natural state. They are left there until the cherry rots away, leaving only the natural coffee beans. However, in Latin America and some other parts of the world, cherries are placed in fermentation tanks where the coffee beans are removed from the cherry. This gives those coffee beans more acidity. Finally, in most parts of Central America, the cherries are washed and then laid out to dry, resulting in a creamier-tasting brew.
In the indirect-solvent method the coffee beans are soaked in near boiling water for several hours, which extracts the caffeine as well as other flavor elements and oils from the beans.
I 8767 ve just decided to switch to decaf during my pregnancy. Not only conscientious of the effect on the bun in the proverbial oven, I also find that the caffeine has a more profound effect on my system, leaving me tossing and turning while my husband saws logs.
Anyway, in a whim and without research, I decided to try Kicking Horse brand Swiss Water Decaf, a Canadian roaster that 8767 s Fair Trade and Organic. It 8767 s quite good! While enjoying it I wondered how they decaffeinated my yummy coffee and found this article, in which I learned I made a lucky choice since all caffeine is not taken care of equally 🙂 So thank you for satisfying my curiosity and thanks to Kicking Horse for satisfying my coffee lover.
And here 8767 s where the magic happens. The flavorless caffeine-free beans are discarded, but the flavor rich water is reused to remove the caffeine from a fresh batch of coffee beans.
Given numerous health scares connected to early efforts in decaffeination (the hit list of toxic solvents includes: benzene, trichloroethylene (TCE), dichloromethane and even chloroform) the solvents of choice have become methylene chloride and ethyl acetate.More pictures: «Organic unroasted coffee beans question».
