how do they make decaf coffee? how's caffeing taken out of beans?
Q :A : Decaffeination
look at this link:
http://en.wikipedia.org/wiki/Decaffeination
are decaf coffee beans darker that regular coffee beans?
Q :
A : no not usually. Some say there is no such bean as decaffeinated coffee beans. They were right but with genetics they have created a decaffeinated bean. It is designed to save the marketers time. I won't knowingly buy
such beans. The normal water process for decaffeinated beans is best. As for the colour of coffee beans that depends on the brand and the method of growing and the type of soil. I know one person in Dorion Ont. grew coffee beans in white clay soil and wound up with pale coffee beans. Someone else grew coffee beans in Red Clay Soil in Red Rock Ont. and would up with dark coffee beans! I wonder why I don't get black coffee beans planting in black
earth! But they aren't pale and aren't dark!
is there such thing as decaf espresso beans? Or can I use regular decaf coffee beans?
Q :
A : Yes, you can get decaf espresso beans. Starbucks has them. I imagine all the other coffee places will have them too.
If a coffee bean has caffeine in it; how is decaf coffee made & what's in it?
Q :
A : All decaffeination processes are performed on unroasted (green) coffee beans, but the methods vary somewhat. They generally start by steaming the beans. The beans are then rinsed in some solvent. The actual solvent depends on the process, but different methods use either methylene chloride, ethyl acetate, liquid carbon dioxide or oxygen, or just good ol' water. The process is repeated anywhere from 8 to 12 times until it meets either the international standard of having removed 97% of the caffeine in the beans or the EU standard of having less than 0.10% caffeine by mass in the coffee at the end of the process.
