We often have customers contacting us with some concern about the leftover moisture in their portafilter post-brew. Depending on the type of machine you have, this will be more or less present -- but is it something that you should be worried about? Is it indicative of an issue with the machine? To allay your fears, we asked Gail to break soupy pucks down for us. Watch as she explains to us what they are, which machines might have soupier pucks than other machines and what, if anything, excess moisture on your coffee puck might mean.
