Because of this thread, I bought some "cheaper" esspresso coffee to test what the difference is. I got a brick of "caffe Mauro", and "Caffe Gioia" and a tin of "Compliments Trattoria Espresso" which is a grocery story chain brand. I usually grind the beans at the grocery store which costs about 2-3 times as much as these ones I'm testing.
This morning I'm trying the "Caffe Mauro". It tastes a little different but not much to me. I usually put about 1/2 teaspoon of suger in my double espresso. I think because I use suger, I'm not as sensitive to the taste of the different brands. I think from now on I'll stick to the cheaper stuff and save some money. Cheers for the thread.
