Details
Most home espresso setups still guess at yield. You watch the stream, stop on feel, and wonder why Tuesday’s shot is sour, and Thursday’s is bitter. One or two grams of output, or a few seconds, is enough to change the cup. A kitchen scale does not fit on a drip tray. A $250 espresso scale bundles an app you may not open.
The LUCCA Precision Coffee Scale is built around the idea that it shouldn’t have to be that way.
This 4 x 4 inch espresso scale has 0.1 g readability, a built-in shot timer, and a water-resistant tempered glass plate. It sits on most home drip trays with a cup on top. It shows time and weight at the same time. One mode. No menus. No app. Tare the cup, start the timer, stop the shot when the number lands.
Use it under the group for yield. Use it under a portafilter for dose. Use it under a dripper for brew ratio. Then put it back on the tray. That is the whole product.
LUCCA Precision Coffee Scale Features That Deliver
0.1 g Readability, 0.3 g to 2,000 g Capacity
Espresso recipes live in tenths. A 36 g shot that lands at 38 g is not “close.” It is a different drink. The LUCCA scale reads to 0.1 g across a working range from 0.3 g up to 2 kg, so it covers a double basket, a V60, and a small pitcher without swapping tools.
Time and Weight on One Screen
The bright LED shows shot time and weight together. You do not need a phone on the drip tray. Start the timer with the dedicated button. Watch ratio and time at a glance. That is how you learn whether a shot ran long because the grind drifted or because you let it go.
Fits the Tray, Survives the Tray
About 4.1 x 4.1 x 0.73 inches and 0.6 lb. Low enough to slide under most home groups with a demitasse or a small glass on the plate. Tempered glass top. Water-resistant build for steam and splashes. Silicone heat pad included so a hot cup doesn't cook the load cell.
USB-C Rechargeable, No Coin Cells
A 500 mAh lithium battery charges over USB-C. Use the included cable. Fast-charge USB-C bricks are not compatible and can cause problems. Charge it on a standard port and leave it on the bar.
Units You Actually Use
Grams, ounces, and milliliters. Double-tap tare to move between units. That is the only “menu.”
What It Deliberately Leaves Out
No auto-start. No flow-rate graph. No Bluetooth recipe log. Those features live on Acaia, and Fellow scales at three to four times the price. If you want a scale that weighs and times a shot without forcing you to learn an app, this is the tool.
Who the LUCCA Precision Coffee Scale Is For
This scale is for the home barista with a real espresso machine who still stops shots by eye. For the person who bought a LUCCA A53, or any compact dual boiler, and needs a tray scale that doesn't cost more than the tamper. For pour-over drinkers who want one scale that also lives under the group.
It’s the right fit for:
- Home espresso bars that need 0.1 g yield and a shot clock on the drip tray.
- LUCCA machine owners who want the matching accessory instead of a generic Amazon scale.
- Anyone stepping up from a kitchen scale that will not fit under the group.
- Brew-bar use with a carafe that fits a 4-inch plate.
Look elsewhere if:
- You want auto-tare when the cup hits the plate, flow rate, or an app. Buy an Acaia Lunar or Pearl.
- You weigh full-size 58 mm portafilters on the scale every shot and want a larger platform. This plate is 4 inches. Some baskets hang over the edge.
- You need café volume and splash abuse all day. This is a home scale.
LUCCA Precision Scale vs. Acaia Lunar
The Lunar is the specialty-coffee standard: faster response options, espresso-specific firmware, flow rate, app, and a price around $250. It is the right buy if you already chase recipes in software and you want the scale the competition uses.
The LUCCA scale does the two jobs that change the cup: weight and time. It costs $70. Choose the Lunar when you will use the extra modes. Choose LUCCA when you will not.
LUCCA Precision Scale vs. Fellow Tally Pro
The Tally Pro is a $200 brew-first scale with Brew Assist, a nicer chassis, and more modes. Better if pour-over is the main drink and espresso is occasional.
The LUCCA scale is thinner, cheaper, and built to live on an espresso drip tray. Choose Tally Pro for the brew bar. Choose LUCCA for the group.
LUCCA Precision Scale vs. generic $25–$40 coffee scales
Cheap scales often read to 0.1 g on paper and drift, lag, or die when they get wet. The LUCCA scale is still a simple two-button tool. The difference is a tray-ready height, a glass plate, a real timer on the same screen, and a rechargeable pack instead of a coin cell you will lose.
If the only number that matters is the lowest price, buy the generic. If you want the scale to still work after a year of steam, buy this.
Key Takeaway
Acaia wins on features and café credibility. Fellow wins on brew-bar polish. Generic wins on ticket price. The LUCCA Precision Coffee Scale is the choice for the home espresso bar that needs 0.1 g, a shot timer, and a drip-tray footprint without paying for an app.

Frequently Asked Questions
Q: Is this accurate enough for espresso?
A: Yes. 0.1 g is the resolution that matters for dose and yield at home. You do not need 0.01 g to pull a better shot. You need a scale you will actually leave on the tray.
Q: Will it fit under my group head?
A: It fits most home machines with a cup on the plate. Height is 0.73 inches. Measure the gap between your drip tray and the spout if you run a tall glass. Some large 58 mm portafilters overhang a 4 inch plate. Weigh dose in a dosing cup if that is your basket.
Q: Do I need a separate timer?
A: No. Time and weight share the display. There is no auto-start when liquid hits the cup. Press the timer when you start the shot.
Q: Is there an app?
A: No. That is the point. If you want recipes in a phone, look at Acaia.
Q: Can I use it for pour-over?
A: Yes, if the brewer or carafe sits stably on a 4 inch plate. Double-tap tare to switch units. It is an espresso-first scale that also brews. It is not a large brew-bar platform.
Q: Why won’t my USB-C fast charger work?
A: The scale is not compatible with fast-charge USB-C cables and bricks. Use the included cable on a standard USB port.
