Tested on a Philips Senseo machine is a standard coffee machine that I usually take pods Senseo "coffee house" classic, that is of equal intensity (No. 3). Clearly I prefer the taste of the "Black Card" which is closer to the espresso consumed in bars with a more pronounced but less "burned" flavor. The pods fit perfectly and the foam produced is identical. So I change my habits to go over to "Black Card". However, attention to packaging 36 pods for when the package is opened for a long time, taste deteriorates despite the closure system with repositionable adhesive.
