• Using a bottomless portafilter may require some adjustments to your grind size, dose, or tamping technique. Channeling or spurting is common at first and is not a defect — it simply helps identify areas for improvement. With a few tweaks, you’ll be pulling cleaner, more consistent shots in no time.
