Gladwise IMS 58mm Baristapro 18g Ridgeless Espresso Basket — 661-hole 0.30mm Nano-Quartz Finish

Gladwise IMS 58mm Baristapro is a precision-engineered 18g ridgeless espresso basket with 661 uniform 0.30mm holes and a nano-quartz non-stick finish for more even extractions.

This 58mm double basket was designed for home baristas and professional machines that need a consistent, metal-neutral extraction. Machined in Italy from AISI 304 stainless steel, its 24mm internal height and 70mm rim diameter suit shallower portafilters and deliver a classic double-style dose. The nano-quartz coating resists corrosion and prevents metallic taste transfer, while the hole pattern aims to reduce channeling and produce a balanced cup.

How does the 661-hole pattern improve espresso consistency?

The basket’s evenly spaced 0.30mm holes create a homogeneous flow of water through the coffee puck, reducing pressure imbalances that cause channeling. Because the holes are offset from the edge toward the center, they encourage even extraction across the entire puck instead of forcing early outlets at the rim.

• 661 precision-drilled holes for uniform spray distribution
• 0.30mm diameter optimized for balanced soluble extraction
• Hole placement reduces rim-based channeling
• Improved crema and more consistent shot volumes

Will this basket fit my 58mm portafilter and tamper?

The Gladwise IMS Baristapro fits most standard 58mm portafilters and works best with tampers sized 58.5–58.8mm. Its 70mm outer edge and 24mm height were chosen to match many commercial and prosumer machines that have slightly shallower filter wells.

• Compatible with broad range of commercial brands and E61-group heads
• Ideal for portafilters with shallower depth or traditional double dosing
• Recommended tamper size: 58.5–58.8mm for optimal puck compression
• Designed to replace standard 58mm baskets for better fit and performance

What benefits does the nano-quartz non-stick finish provide?

The nano-quartz coating prevents flavor contamination from metal and reduces staining or discoloration over time. It also increases resistance to chemical reactions and corrosion, making the basket easier to clean and preserving its appearance and performance over repeated use.

• Non-stick surface eases puck release and cleaning
• Protects against corrosion and discoloration
• Helps maintain neutral flavor profile in cup
• Durable finish suited to daily commercial use

How does the basket’s size and shape influence shot style?

With an 18g capacity and a 24mm height, this basket supports a denser, more traditional double espresso profile. Baristas who prefer a slightly shorter chamber—or those adapting to different grind distributions—will find the basket encourages classic extraction timing and mouthfeel.

• 18g nominal capacity for concentrated double shots
• 24mm depth suits shallower filter wells and tighter puck geometry
• Edge Ø 70mm fits many commercial portafilters without modification
• Engineered to balance soluble yield and crema production

Who is this for? The Gladwise IMS Baristapro Nanotech Ridgeless basket is aimed at experienced home baristas, café operators, and equipment technicians seeking a drop-in upgrade for 58mm setups. It’s especially useful for those chasing greater extraction uniformity, easy maintenance, and a neutral metal footprint in the cup. Choose this basket if you want a precision-engineered, made-in-Italy component that improves shot repeatability and integrates with a wide range of commercial espresso machines.
