new barista here. in the place that im working we are using 7grams of espresso for a single shot. so are using two different portafilter for one shot or double shot. whenever i make a single shot with the little(?) portafilter even if i wait for a loooong time after i hit it to the knockbox it comes out soggy. but when i make the double shot with the bigger portafilter. it comes out clean. i added pictures of the portafilter. what is the issue? can u help me.
