Spouted Vs Bottomless Portafilter: Which Is Best For Espresso Beginners? - Tasting Table
Briefly

Upgrading your morning routine with homemade espresso requires the right equipment, especially the portafilter. Jee Choe, a coffee sommelier, advises on the differences between spouted and bottomless portafilters. Spouted portafilters are mess-free and easier for beginners, but they mask extraction mistakes. In contrast, bottomless portafilters provide clear visibility of extraction issues but can create spills during use. Ultimately, choosing the right portafilter impacts the quality of espresso shots you will produce at home.
Spouted portafilters are easier for beginners to use since there will be less of a mess if the grind size is off or if the tamp isn't even.
Bottomless portafilters show immediately if there are any extraction issues since you can get a direct view, but can get messy.
