That strong, rich espresso shot wouldn’t be possible without a portafilter. One of the main components of an espresso machine, the portafilter is where your coffee grounds sit as water runs through them to make coffee.
As a result, the portafilter will contain the used-up grounds after pulling the shot, which for the most part, means that cleaning is due. If you’re wondering why and how to clean the portafilter between shots, then keep reading!
Why Portafilter Cleaning is Important
Imagine pulling an espresso shot using a dirty machine, do leftover oils and impurities floating in your cup of coffee sound delicious? I’ll bet you said no.
Of course, you’d be right! Not even the best, most expensive coffee beans can justify or make a shot pulled through a dirty portafilter taste good.
If you’re a coffee enthusiast, then you already know that the thick crema topping your espresso comes from the essential oils in your coffee beans. These oils have an ugly side though; they’re also the reason behind that “off” flavor of coffee that develops after a while.
This rancidity happens when the oils emulsify and stick to the metal water screen (sometimes behind it as well) of the espresso machine. This results in the formation of a film on the filter basket and portafilter.
Shot after shot, this film will build up to the point it clogs the holes of the portafilter basket and leaves residue inside the portafilter spout. Now, if you could remove such nasty impurities, why wouldn’t you?
Luckily for all of us coffee lovers, these deposits can be easy to remove as long as you opt for regular cleaning.
How often to clean the portafilter?
We recommend cleaning the portafilter every 10 shots. At home, however, the demand is far less so there’s no reason to leave it dirty. For convenience, consider cleaning the portafilter right after pulling your shot and before drinking your coffee – just get it out of your way.
Should I clean the portafilter between every shot?
You don’t have to clean the portafilter after every shot you pull. Doing so will certainly make things easier in the long run, but it’s not exactly possible if you work at a coffee shop pulling dozens of espresso shots daily.
How to empty the espresso filter?
If you’re wondering how to empty the portafilter, actually it’s very simple all you have to do is turn it upside down then give it a shake or lightly tap over your knock box or sink until the puck becomes loose and drops out.
Now that the questions of “why” and “how often” are over with, it’s time to get your hands dirty!.
