This is my second MCOTCH (first was replaced due to water not circulating through machine) This machine brews a approx.  2oz/4oz on Capp and 4oz/6oz on latte settings. I have used a standard Folgers coffee and a Cafe' Bustelo Espresso Ground (leaves water in filter) I have tried a "reset" (empty reservoir unplug 5 minutes). Nothing helps. I am able to manually add more using the Manual button. Great taste, good conversational piece even a great look when brewed in glass cup (which I recommend), but it would be nice if the cups brewed to correct volume.
