xMaestri House S3: Precision and versatility for home baristas
The Maestri House S3 Coffee Scale with Timer brings professional-grade precision into a compact home setup. With a 3 kg capacity and 0.1 g accuracy, this scale is designed to support accurate dosing, repeatable pours, and mindful pacing across different brewing styles. A sleek, one-piece matte body sits on your counter, while a large, easy-to-read display keeps weight and time information visible as you pour.
Three smart brewing modes for flexible practice
Choose Auto Timer for Pour-Over, Auto Timer for Espresso, or Standard Weighing. Each mode adapts to your method, helping you track weight and time without guesswork. The dual-zone LED interface clearly presents weight, time, and flow in real time, so you can stay focused on technique rather than toggling settings.
- Auto Timer for Pour-Over: captures bloom and steady pours with a cue when you reach the target ratio.
- Auto Timer for Espresso: locks in dose and shot time for consistent pulls.
- Standard Weighing: straightforward weight readouts for any method.
Smart ratios, simple accuracy
Dial in your brew with ratios from 1:1 to 1:18. The scale auto-calculates the target water weight and provides a soft beep when your target is reached. Real-time flow rate display helps you refine your pour for balanced extraction across Chemex, V60, and other hand-brew methods.
- Automated ratio guidance supports a wide range of brew styles
- Flow rate feedback assists in shaping your pour
Long-lasting power and resilient design
Rechargeable via USB-C, the S3 offers up to 90 days of use on a single charge. A splash-resistant IPX4 display, heat-resistant silicone pad, and a durable matte shell make it a reliable companion for daily coffee routines and high-temperature brews.
Quiet, user-friendly operation
Smart touch controls paired with a dual-zone LED panel deliver fast, legible readings. If you prefer a calmer morning, Silent Mode deactivates beeps, letting you focus on technique without distraction.
Practical takeaway
From a quick daily coffee ritual to more measured home experiments, the S3 helps you observe weight, time, and flow in tandem. It’s designed to support consistent practice, with features that adapt to how you brew.
