@baristainpajamas: Your knock box might be doing more damage than you think. ☕️ Hitting your portafilter too hard can slowly bend the basket rim, especially on thinner baskets. That small change can affect the seal and eventually cause leaks around the portafilter. Try a few firm taps with your hand first. It helps release the puck and puck screen with much less stress on the basket. Your espresso setup will thank you. 😂 #espresso #homebarista #coffeetips #espressotips #espressomachine
