Description Details

The FILTER 21G "X" (Part No. F.3.026.X) is the ultimate upgrade for baristas seeking maximum extraction capacity and flawless consistency from their commercial espresso machine. Engineered for high-volume use, this precision-machined filter basket holds approximately 21 grams of coffee, allowing for higher dosing, which is essential for maximizing flavor clarity and strength in modern espresso recipes. Made from durable, food-grade stainless steel, the F.3.026.X features uniform, micro-fine holes that guarantee even water flow and resistance across the coffee bed. This basket is specifically designed to fit standard 58mm portafilters compatible with most major commercial machine brands (check machine compatibility for group head clearance), offering an immediate solution if you are asking "How to fix under-extracted shots in a busy cafe?" or "Why does my espresso taste weak with standard baskets?"

Using the FILTER 21G "X" provides significant benefits for both workflow and beverage quality. The large capacity allows you to serve more substantial, richer double shots without needing multiple tamps or extra steps, directly addressing the "Problem: inconsistent shot weight" by promoting dose repeatability. Its robust construction resists warping and corrosion, ensuring a long service life even under daily back-flushing and heavy production schedules. For optimal usage, we recommend pairing this 21g filter with a calibrated tamper and a high-precision grinder capable of producing fine, consistent grounds. This basket minimizes channeling—the common "Problem: uneven espresso extraction"—by creating a deep, uniform puck for superior saturation and flavor yield.

Specifications for the FILTER 21G "X" (F.3.026.X) include a nominal diameter of 58mm, a depth engineered for 21g ± 1g dry coffee capacity, and a precise hole pattern optimized for commercial pressures. If you are experiencing the "Problem: coffee grounds clogging my shower screen," the height of this basket helps maintain adequate headspace. When installed correctly, the F.3.026.X is a vital tool for baristas focused on quality control, offering a tangible solution for "How to achieve consistent flavor profiles in high-volume espresso production." Upgrade your portafilter today and stop settling for mediocre shots caused by restricted capacity or poor filtration.
