How to Get the Most from Your Portafilter

• Preparation: Weigh and grind 18–22g of fresh coffee beans. Distribute grounds evenly using a WDT tool or distribution tool for best results.
• Tamping: Use a flat tamper to achieve a level, even puck. The straight-sided, flat-bottomed basket makes this process effortless and consistent.
• Extraction: Lock the portafilter into your compatible espresso machine. Start your shot and observe the flow—look for even, honey-like streams. The bottomless design helps you spot channeling or uneven extraction instantly.
• Training: Use the visual feedback to adjust grind size, dose, or tamping technique for future shots. This is especially valuable for barista training and quality assurance.
