I have a Delonghi EC9 and I want to make only a single shot. But, when I put the half amount of coffee in the portafilter the cup don't brew well.
These are low-end machines. Sometimes they do not ship them with a single shot portafilter to keep the costs low. If this is your case, means, if you don't have a single size portafilter you cannot make a single shot. See the differences on this post:
My humble advise is, get used to drinking doppios. :)
Can i buy a single shot porta filter? Dec 2, 2018 at 22:30
It may be possible. But portafilters do not have standard sizes. Please check here: coffee.stackexchange.com/questions/3800/…– MTSanDec 3, 2018 at 11:07
