Consistency transforms a good cup of coffee into one you can enjoy again and again. The Hario POLARIS Scale is designed to bring confidence to every brew by guiding you through each step with thoughtful, real-time feedback.

More than a digital scale, POLARIS helps simplify recipe building by calculating an extraction ratio based on the amount of coffee you're brewing. As you pour, the display tracks your progress, showing exactly how much water has been added and what percentage of your brew is complete. The result is a brewing experience that feels intuitive, informative, and easy to follow.

Whether you're refining a favorite recipe or exploring new coffees, the Hario POLARIS Scale provides the precision and guidance to make every pour feel more intentional.

Smart digital coffee brewing scale with integrated timer
Measures coffee and water from 0.1 g to 2,000 g
Calculates recommended water volume based on your selected extraction ratio
Displays real-time brewing progress as a percentage throughout your pour
Built-in timer supports consistent brewing workflows
Adjustable extraction ratio settings help tailor your recipe to your preferred coffee strength
Suggested ratio ranges:
- Lower ratios (approximately 1:1–1:14) for a stronger, more concentrated cup
- Higher ratios (approximately 1:15–1:30) for a lighter, more delicate cup
- Example: Using 20 g of coffee with a 1:15 ratio recommends 300 g of brewing water
