Grind by Weight Accuracy

Unlike traditional timed grinders, the Libra 65 AP GBW dispenses coffee based on its actual weight.

Every dose is measured with exceptional precision, resulting in:

Outstanding shot-to-shot consistency
Reduced coffee waste
Faster dialing in
Improved extraction repeatability
Greater recipe accuracy

Grind by Weight technology is particularly valuable for espresso preparation, where even small dose variations can significantly affect extraction quality.

Newly Designed 65 mm All-Purpose Burr Set

One of the most significant upgrades over the original Libra is the completely redesigned 65 mm hardened steel flat burr set.

The larger burrs provide:

Faster grinding
Lower heat generation
Improved particle consistency
Better flavour clarity
Greater workflow efficiency

Unlike the espresso-focused burr geometry found on previous models, the All-Purpose (AP) burr design delivers exceptional performance across the full spectrum of brewing methods.

From fine espresso grinding to coarse cold brew settings, the Zero 65 AP GBW maintains outstanding grind uniformity.

Blind Burr Design for Lower Retention

The Libra 65 AP GBW features Eureka's innovative blind upper burr design, eliminating exposed mounting screws from the grinding surface.

This creates:

More uniform grinding
Lower retention
Improved particle distribution
Easier cleaning
Better overall consistency

Combined with the grinder's low-retention grind chamber and bellows system, virtually every gram of coffee reaches your portafilter or dosing cup.

Redesigned Stepless Grind Adjustment

Switching between espresso and brew coffee has never been easier.

Eureka completely redesigned the grind adjustment system by introducing:

Oversized aluminum adjustment dial
Extended 0–20 adjustment scale
Precision stepless adjustment
Integrated revolution counter
Highly visible red reference markings

The built-in rotation counter records how many full revolutions you've made when adjusting grind size, making it incredibly easy to return to previous settings after switching between brew methods.

This dramatically reduces the trial and error normally associated with changing grind settings.

Professional Low-Retention Workflow

Designed around modern single-dose coffee preparation, the Zero 65 AP GBW incorporates several workflow-enhancing features:

Low-retention grinding chamber
Integrated bellows system
Anti-static coffee delivery
Anti-popcorning system
Anti-chaff funnel
Automatic grind stop
Clean coffee path

The result is a grinder that minimizes waste while maximizing freshness.

Quiet Yet Powerful Performance

Powering the Libra 65 AP GBW is a robust 310 Watt AC motor operating at 1,350 RPM.

The motor is engineered for long-term reliability while Eureka's renowned Silent Technology significantly reduces grinding noise through an advanced anti-vibration system.

Benefits include:

Quiet operation
Consistent grinding speed
Reduced vibration
Improved durability
Professional reliability

Built for Espresso and Filter Coffee

The Libra 65 AP GBW truly lives up to its "All-Purpose" name.

It excels with:

Espresso
Pour Over
V60
Chemex
Kalita Wave
AeroPress

Instead of owning separate grinders, users can confidently switch between brewing methods while maintaining exceptional grind quality.

Bottomless portafilters
