Delicious coffee - without the kick! The Swiss water decaffeination process is an organic, 100% chemical-free method, discovered in the 1930s in Schaffhausen, Switzerland. This decaffeination process gently and naturally removes caffeine without affecting the proteins and carbohydrates so the delicious flavours are retained in the beans. Thanks to some scientific smarts and creativity, it’s possible to have decaf coffee that tastes the same, just without the caffeine! Bag size: 250g. Based on an average measure of 6-8g of coffee per espresso, each bag contains c36 shots, at 18p each.
