Maestri House Espresso Scale S2 — 0.1g Precision Shot Scale, USB-C Rechargeable, Borosilicate Glass

The Maestri House S2 is an ultra-compact espresso scale with 0.1g accuracy and an integrated timer to help home baristas dial consistent shots.

Compact enough to sit on a crowded counter, the S2 combines high-sensitivity weighing, dual timing modes, and a borosilicate glass surface to deliver repeatable dose and yield measurements for espresso, pour-over, and small-batch brewing. It reads from 0.5g up to 2001g, offers g/oz/ml units, and is USB-C rechargeable for convenience—no disposable batteries required. The hidden LED display and detachable silicone pad keep the design minimal while protecting surfaces and reducing vibration.

How precise is the S2 for dialing espresso doses?

The S2 uses sensitive sensors and a stable microprocessor to report weight to 0.1g increments, making it suitable for fine adjustments to espresso dose and yield. Its accuracy across a wide range covers small single doses as well as group-head baskets and kettles.

• Resolution: 0.1g for repeatable micro-adjustments
• Weighing range: 0.5g–2001g for shots, cups, and containers
• Stable microprocessor minimizes drift during extraction

What timing features help control extraction?

The S2 includes both automatic and manual timing modes so you can track extraction seconds precisely. Automatic timing can start with weight detection, while manual lets you control the start/stop for advanced routines.

• Dual modes: automatic (weight-activated) and manual timer
• Visible LED countdown integrated into the glass surface
• Press-and-hold controls to mute feedback for quiet brewing

How durable and convenient is the build for daily use?

The top is borosilicate glass for heat resistance and easy cleaning, paired with a detachable silicone pad to prevent slips and protect machine trays. The compact 4.13 × 4.13 × 0.79-inch footprint fits most espresso machine drip trays and small pour-over setups.

• Premium borosilicate glass surface resists heat and scratches
• Detachable silicone pad for anti-slip grip and surface protection
• Palm-sized design fits compact machines and limited counter space

How long does the battery last and how is it charged?

The S2 has a built-in 500mAh lithium battery designed to last up to about 90 days under typical daily use and power-saving sleep mode. It charges via a USB-C cable included with the unit, removing the need for disposable batteries.

• 500mAh rechargeable battery, USB-C charging included
• Sleep mode after ~6 minutes of inactivity conserves energy
• Portable for travel or retail demo use without frequent recharging

Who is this for? The Maestri House S2 is aimed at home baristas and small-batch brewers who need high-resolution weighing and precise timing while saving counter space. It's suited for anyone dialing espresso doses, tracking yield and extraction time, or wanting a clean, modern scale that fits most machine drip trays and travel sets. If you need a compact, rechargeable scale with professional-grade resolution and user-friendly timing features, the S2 provides a streamlined tool for consistent daily brewing without complicated setup.
