Low caffeine coffee : ウィキペディア英語版 | Low caffeine coffee Low caffeine coffee is a term that is used by coffee producers to describe coffee that has not been subjected to a process of decaffeination, but is substantially lower in caffeine than average coffee. Samples of coffee vary widely in caffeine levels due to many elements, some that are well documented (such as genetics) and some not fully understood, such as the action of soil, water levels and sunlight. Low caffeine coffees are typically created by assaying caffeine levels of different bean lots and selecting the best flavor profile from the lots that are naturally lowest in caffeine. ==Decaffeination== (詳細はcoffee bean. During the process of decaffeination, the largest coffee producers in the world use a variety of ways to remove caffeine from coffee, often by means of chemical manipulation and the use of potentially harmful chemical components, such as methylene chloride or ethyl acetate. One process that does not use solvents is the patented Swiss Water Process,〔http://www.swisswater.com/process〕 which relies on soaking beans in a bath which is essentially brewed coffee from unroasted green beans. The caffeine permeates into the bath at a much higher rate than most of the flavor elements. While the process is certified organic, the water solubility of coffee flavor compounds assures that some of the coffee flavor is lost or changed by the bath. The process is more costly than solvent methods, and is performed commercially by only one plant in British Columbia, Canada. Therefore only a small percentage of decaffeinated coffee available on the market uses this method.
