• *USEFUL TIPS*: Too much or too little ground coffee and uneven distribution can cause splashing. Try different grinds of ground coffee to prevent it from becoming too fine or too coarse. Then use a tamper to compact the ground coffee. You can try to solve more problems through YouTube
• 90% of leaks come from grind being too coarse, not a bad fit. Coarse grind + fast water flow + no pressure = water seeps from the edge. Grind finer (But be careful not to overdo it and clog the flow.) — pressure builds, water flows through the puck, not around it. Fix the grind, fix the leak
• When brewing espresso, how is crema produced? The following 4 conditions must be met simultaneously: 1.Fresh beans (over 3 months old → almost no Crema) 2.Grind size is correct (too coarse → fast flow → no Crema; too fine → no extraction) 3.Bar pressure (machine’s job, not the basket's) 4.Proper dose (too little → large gaps → no pressure buildup)

Buyer’s Guide: What to Consider

Choosing the right bottomless portafilter involves more than just picking a brand. Consider these key factors to ensure you get the best fit for your machine and brewing style.

• Compatibility: Ensure the portafilter fits your espresso machine's diameter (51mm or 54mm) and ear configuration (2 or 3 ears). Check the model list to avoid mismatches.
• Included Accessories: Some portafilters come with a filter basket, puck screen, or both. These add value and save you from buying extras separately.
• Handle Material: Handles range from anodized aluminum to walnut or rosewood. Choose based on comfort, durability, and aesthetics. Wood requires occasional care.
• Basket Capacity: Baskets vary from 16g to 21g. Higher capacity allows for stronger shots, but ensure your grinder and machine can handle the dose.
• Build Quality: Look for food-grade stainless steel heads and polished finishes. These resist corrosion and ensure a clean, long-lasting product.
