The G-IOTA Gen 2 grinder, also known as the DF64 Gen 2, has garnered attention for its notable improvements and solid performance in the home coffee grinder market.

Build Quality and Design

The G-IOTA Gen 2 features a compact design, measuring approximately 225mm x 130mm x 300mm, making it suitable for limited countertop space. It boasts a robust build primarily made of metal, providing a sturdy and durable feel. The grinder includes a plastic dosing cup, which some users recommend upgrading to stainless steel for a more premium experience.

Burr and Motor Performance

Equipped with 64mm flat burrs, the grinder offers commercial-level grind quality at an accessible price. The stock burrs provided by Italmill can be upgraded to SSP burrs for enhanced grind quality. The motor is a 250-watt unit operating at 1400 RPM, powerful enough to handle various burr sets and provide consistent grind performance.

Grind Quality and Versatility

The G-IOTA Gen 2 excels in grind consistency, particularly for espresso. It features a stepless grind adjustment, allowing for precise dialing in of grind sizes, which is crucial for achieving optimal espresso shots. However, for coarser grind settings like French press, the grind uniformity decreases slightly, although it remains competent for pour-over methods​.

Key Improvements in Gen 2

Several enhancements distinguish the Gen 2 from its predecessor:

• Plasma Generator: This feature significantly reduces static, preventing coffee grounds from sticking and creating a mess.
• Anti-Popcorning Disc: It minimizes bean jumping during grinding, improving consistency and reducing grind time.
• Redesigned Declumper: The new declumper design addresses previous clumping and grind retention issues, making the process smoother and cleaner.

The grinder comes with useful accessories like a high-quality dosing cup and a wooden cap. Maintenance is straightforward, with the redesigned burr carrier simplifying disassembly for cleaning.

The G-IOTA Gen 2 grinder is a significant upgrade from its predecessor, addressing key issues and introducing new features that enhance user experience and grind quality. It stands out as a high-performance, economical option for home coffee grinding, particularly for those focused on espresso.
