Scales, measurement
Two scales, two jobs. Espresso needs speed and 0.1 g; pour-over needs a timer that starts itself and a shape that fits a dripper.
The scale is the least interesting purchase in coffee and one of the most consequential, because everything else you do is an attempt to be repeatable and you cannot repeat what you did not measure.
Three specifications separate a coffee scale from a kitchen scale: resolution, refresh speed and footprint. Which of them matters depends entirely on whether you are standing over a portafilter or a dripper, which is why the two picks below are not really competing.
The minimum and most useful use: without a weighed dose, no setting is repeatable from one day to the next.
Weighing the drink as it runs tells you when to stop. That is where refresh rate counts.
Weight and time together describe an extraction. A built-in timer saves juggling a phone with wet hands.
In pour-over, pouring by weight rather than by eye removes one source of variation between brews.
| Your method | What counts | What does not |
|---|---|---|
| Espresso | Refresh rate | Very fine resolution |
| Pour-over | Timer, large platform | Extreme speed |
| Weighing beans | Nothing special | Dedicated features |
| Daily use | Sealing | Styling |
A coffee scale does not wear out, it drowns. Moisture gets in through the keys and the battery compartment, and corrosion does the rest. No lifespan can be quoted: it depends almost entirely on exposure to water.
2 kg × 0.1 g · flow rate · under-portafilter footprint
Fast enough for espresso, small enough for a drip tray, and it shows flow rate — which is the one number that tells you what your shot is doing while it is still happening.
Best for: Espresso, where 0.1 g and a fast refresh genuinely change what you can control.
≈ $60 / £50 / 55 €
2 kg × 0.1 g · auto timer · V60 footprint
Built around the V60 rather than adapted to it: the footprint fits a dripper and a carafe, and the timer starts on its own when the first drops land.
Best for: Pour-over and immersion brewing, where a timer matters more than refresh speed.
≈ $60 / £50 / 55 €
For espresso, yes — an 18 g dose and a 36 g yield mean a gram is over 5 per cent of the target. For filter, 1 g is plenty, because you are weighing 15 g of coffee into 250 g of water and a gram is noise.
Because a slow scale shows you what happened half a second ago, so you stop the shot late and overshoot your target yield every time. Under a portafilter, a fast refresh is worth more than another decimal place.
Water. They sit on drip trays and next to kettles and almost none of them are sealed. A silicone mat underneath and a wiped tray roughly doubles the life of any scale in this price range.
For weighing beans, yes. For following a brew, no: the display lag and the resolution make it unusable while the coffee is running.
Weighing both gives you a ratio, and it is the ratio that repeats from day to day. Weighing the dose alone is already a large step forward.
Machine vibration, an unstable platform, or moisture. A scale on a firm surface and away from splashes settles far better.
For pour-over, yes: time and weight read in one place, with no phone to touch with wet hands. On espresso it is one more convenience.
By putting a known weight on it now and then. A coin of standard mass makes a good enough reference to spot drift.
For : Espresso, where 0.1 g and a fast refresh genuinely change what you can control.
Main strength : 0.1 g resolution with a genuinely fast refresh — usable live under a portafilter
Main limitation : Not waterproof — a drip tray is a wet place and this is a known weak point
For : Pour-over and immersion brewing, where a timer matters more than refresh speed.
Main strength : Auto-start timer triggered by the first drops — one less thing to do mid-brew
Main limitation : Slower refresh than espresso-focused scales; you can overshoot

Specifications are those published by the manufacturer and on the Amazon product page; prices are what Keepa reported on the date below, and both move. The ranking uses declared specifications, the balance of stated strengths and limitations, and price. No product on this site has been physically tested, and nothing here claims otherwise.

Espresso machines and grinders swing by a hundred euros or more across the year, and the biggest "discounts" often land at prices the same model sold for six weeks earlier. UniverTrack tracks the real price history across retailers, spots fake reductions, and alerts you when it is genuinely the moment to buy.
