## Brewista Smart Scale 3: Specifications

![Brewista Smart Scale coffee scale review](https://coffee-guide.jp/images/articles/gear/brewista-smart-scale-review-section-1.webp)


| Specification | Detail |
|---------------|--------|
| Resolution | 0.1g |
| Maximum capacity | 2,000g |
| Modes | 5 built-in modes |
| Power | Rechargeable lithium-ion battery (micro USB cable included) |
| Water resistance | Water-resistant nano coating (not fully waterproof) |
| Dimensions | ~10.5cm (W) × 1.7cm (H) × 10.5cm (D) |
| Weight | ~163g |

The Smart Scale 3's core strength is **response speed**. Weight changes are displayed with minimal lag, allowing real-time control of pour rate during extraction.

## Pour-Over Performance

**Blooming phase**
Pouring a precise 30g bloom dose is straightforward — the scale responds quickly enough that stopping flow at exactly 30g is achievable with practice. This precision directly improves recipe reproducibility.

**Main pour phase**
Multi-pour recipes (e.g., 50g / 100g / 50g intervals) are tracked cleanly. The simultaneous display of weight and elapsed time gives enough information to estimate pour rate without additional tools.

**One-handed operation**
The button layout and display size allow effective operation while holding a kettle. The platform provides good stability for a range of cup and server sizes.

The Smart Scale 3 is best suited for intermediate to advanced home brewers who want recipe reproducibility without the complexity of app-connected scales. If you want to brew the same recipe precisely every day, this scale delivers.

## Brewista Smart Scale 3 vs. Acaia Pearl S

| Comparison | Brewista SS3 | Acaia Pearl S |
|-----------|-------------|--------------|
| Resolution | 0.1g | 0.1g |
| Bluetooth | No | Yes |
| App connectivity | No | Yes (Acaia app) |
| Water resistance | Water-resistant nano coating | IPX5 |
| Approx. price | ¥15,800 | ¥40,000 |

Accuracy and response are comparable between both scales. The Acaia Pearl's advantage is app connectivity for logging and analyzing brewing data — useful for competitions and systematic recipe development.

The Smart Scale 3's advantage is simplicity. No phone required, no app to open, no connection issues — just weigh and brew. **For home use, the Smart Scale 3 covers 95% of what most brewers need at less than half the price.**

## Build Quality and Durability

The scale has a clean matte black design that fits unobtrusively in a kitchen setting. It is made of ABS resin and stainless steel, and comes with a silicone pad and a protective cover (tray). A water-resistant nano coating handles splash and drip from pour-over without issue — not fully waterproof, so do not rinse or submerge it.

It runs on a rechargeable lithium-ion battery, and the included cable is micro USB.

## Who This Scale Is For

- Home brewers pursuing pour-over consistency
- Those who want pro-grade accuracy without app complexity
- Coffee enthusiasts who find Acaia Pearl's price hard to justify
- Specialty coffee drinkers who want the same tools as café baristas


**Pros**
- 0.1g accuracy and fast response at half the price of Acaia Pearl
- Simple UI requires no app or phone pairing
- Rechargeable lithium-ion battery, no disposable batteries needed
- Water-resistant nano coating handles drips during brewing

**Cons**
- No Bluetooth — no app for logging brewing data
- Less brand recognition than Acaia in international coffee communities
- 2,000g capacity maximum — not suitable for batch brewing setups
