This particular method of decaffeination is different from what we’ve so far seen in that it does not directly or indirectly add chemicals to extract the caffeine. Rather, it relies entirely on two concepts, namely solubility and osmosis, to decaffeinate coffee beans.
"A mixture of water and green-coffee extract that has alreadybeen reduced in caffeine is circulated around the coffee beanswithin the extraction battery (oils in the coffee extract aid inthe decaffeination process). After a predetermined time, thevessel that has been exposed to the low-caffeine extract isisolated and emptied. The decaffeinated coffee beans are thenrinsed and dried, and a vessel containing fresh green coffee isput on stream. The caffeine-rich extract that was drawn off fromthe vessel containing the fresh, green coffee is passed througha bed of activated charcoal, which absorbs the caffeine. Thischarcoal has been pretreated with a carbohydrate, typicallysucrose, that helps it absorb caffeine without removing othercompounds that contribute to the flavor of the coffee. Thesucrose blocks carbon sites that would normally absorb sugarsfrom the liquid, green-coffee extract. The caffeine-reducedextract can then be reused to begin the process anew. The waterprocess is natural (that is, it does not involve any chemicals),but it is not very specific for caffeine; it removes 94 to 96percent of the caffeine.
Decaffeinated coffee beans can be - and should be - just as delicious and dynamic as regular coffees, so we give it the same care (with less buzz) in our packaged decafs.
illy decaf coffee beans by the full case. 12 x 250g fresh sealed tins, the illy signature taste from 100% arabica beans, taste without the caffiene.
