Your espresso tastes sour — do you grind finer, tamp harder, or change your dose?
The answer might already be on your coffee scale display.

Modern espresso scales — like the MANTABREW WeighMaster — do more than measure grams. They help you see your brew in real time, giving you live feedback on flow rate, extraction time, and final yield — the three key elements of espresso consistency.

The Espresso Trifecta: Flow Rate, Time & Yield

These three variables are inseparable:

A scale that tracks all three helps you dial in your espresso like a pro.

What Is Flow Rate in Espresso?

Flow rate = yield ÷ time.
It tells you how fast water is moving through the puck.

A slow flow often means:

• Grind is too fine

• Dose is too high

• Channeling is blocked

A fast flow may mean:

• Grind is too coarse

• Puck is underfilled or cracked

• Tamping was uneven

✅ Real-time flow rate lets you see problems before you taste them.

Time Isn’t Everything (But It Still Matters)

Many baristas rely only on timing — but it’s not enough. A 30-second shot can be over- or under-extracted if flow rate and yield aren’t aligned.

With the WeighMaster Coffee Scale, you get automated timing from the first drip, with no need to press a button mid-pull.

Yield: Your Final Output

Yield = what ends up in your cup.
Standard is ~1:2 brew ratio (e.g., 18g in, 36g out). But without a scale, you’re guessing — and small errors in yield can throw off taste drastically.

With weight, time, and flow on a single screen, you get the complete picture.

How to Read a Smart Scale (Like WeighMaster)

Let’s say your display shows:

• Time: 27.6s

• Yield: 36.8g

• Flow: 1.33 g/sec

This means you likely need:
→ Finer grind or higher dose, as the flow is slightly too fast for that time/yield combo.

Now imagine it says:

• Time: 32.5s

• Yield: 35.0g

• Flow: 1.08 g/sec

This tells you your shot may be over-extracted — time is long, flow is slow. Adjust grind or lower the dose.

📈 With consistent readings, you can build and repeat your espresso “recipe.”

Train Your Taste With Your Scale

Using a smart scale helps you connect data to taste. Try this:

1. Pull 3 shots at different flow rates (1.1 / 1.8 / 2.5 g/sec)

2. Taste and take notes on clarity, body, sweetness

3. Save your preferred ratio + flow rate as your go-to recipe

The WeighMaster’s live readouts + memory + speed make this a simple but powerful routine.
