What is an acceptable rate of flow from a bottomless portafilter?
Brazil Moreninha Formosa Day 5
For me, I try to keep it to a mouse tail. While I know this is applicable
to those stock portafilters with their bottoms intact, I’m not sure
about the bottomless. Something to look in the forums for. My ideal for
a well-rested coffee would be to do a 45 second ristretto, where the
flow is sticky, gooey, and drips down like chocolate fudge, and I’ll
cut the flow at the slightest hint of pale. Intense.
