For extra-strong coffee: aromaDouble Shot. Extra-strong coffee without compromise on aroma, thanks to the innovative function of the aromaDouble Shot. The aromaDouble Shot feature includes two grinding and burning processes to always extract the best aroma. This automatic process ensures that the coffee is devoid of bitter aftertaste, because less water means less unreleased bitterness — so that only the best in the grain goes into your cup.
