• 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.

Wood Handle Care Instructions

Our wooden handles are made from natural wood, so each piece has its own unique grain and colour. With proper care, your handle will age beautifully over time.

To keep your handle in good condition:

• Do not place in the dishwasher
• Avoid soaking or prolonged contact with water
• Wipe dry after use if wet
• Do not leave attached to a hot group head for extended periods when not in use
• If possible, occasionally apply a small amount of food safe mineral oil to help maintain the wood and prevent drying or cracking

As wood is a natural material, slight changes in colour and texture over time are normal and part of its character.
