Hario Polaris Digital Scale CST-2000-B – Smart Brew Control for Consistent Pour-Over Extraction

The Hario Polaris Digital Scale CST-2000-B is a precision brewing instrument designed for baristas and enthusiasts who value accuracy, consistency, and intentional coffee preparation. Offering high-sensitivity weight measurement, an integrated brewing timer, and a dedicated ratio mode, this scale allows full control over every phase of the pour-over process — from bloom development to the final brew yield. It supports repeatable recipes and traceable extraction, making it ideal for both home brewing and professional café environments.

The scale is built from durable, heat-resistant materials, featuring a stable non-slip platform that maintains secure footing even during fast workflow. Its compact, low-profile form positions the dripper and server at a comfortable visual height, improving pouring precision and reducing hand and wrist strain. With a weighing capacity up to 2,000 g and responsive incremental measurement, it performs equally well for single-cup brews and larger batch extractions.

Intelligent Ratio Mode

One of the defining features of the Polaris is its ratio function, which displays the relationship between water and coffee in real time. This helps dial in recipes accurately and consistently, supporting flavor clarity, sweetness, and body. For baristas refining brewing technique, the scale becomes a feedback tool — translating movements, timing, and grind adjustments into measurable brew outcomes.

High-Precision Timer + Sensor

The built-in timer works in either automatic or manual mode. Auto-start triggers when the first drops of water hit the dripper, useful during busy workflows or consistent training repetition. The sensitive weight sensor responds instantly to changes in water flow, allowing smooth and controlled pour adjustments.

Designed for Everyday Brewing and Training

The Polaris is suitable for:

• Specialty cafés that need reliable recipe and flavor consistency

• Home brewers pursuing high-quality pour-over technique

• Coffee training spaces and workshops

• Pour-over methods such as Hario V60, Kalita Wave, Chemex and hybrid dripper systems

Its user interface is intentionally minimal: Weight, Timer, Ratio, Reset. No unnecessary distraction — only the controls that matter for proper extraction.

Built to Perform, Built to Last

The construction materials resist heat, steam, and coffee oil buildup. Surfaces are easy to clean and maintain, even with daily use. The slim profile and quiet tactile buttons make it well-suited for brew bars with continuous workflow.

The Hario Polaris Digital Scale CST-2000-B is not simply a kitchen scale — it is a professional coffee brewing tool designed to support precise, repeatable, and expressive pour-over coffee.
