The Fellow Tally Pro is a premium scale for someone who wants a clearer pour-over routine, especially when brewing different coffee doses. Its main attraction is Brew Assist: choose a coffee-to-water ratio and follow a target rather than doing mental arithmetic while pouring. You can make excellent coffee with a simpler scale, so buy this one for the workflow rather than assuming its price improves flavor automatically.

Best for and who should skip it
Tally makes sense for a manual brewer who regularly changes dose size, wants the target water weight visible, and values an integrated timer. Someone making one cup today and two tomorrow can keep the same ratio without rewriting a recipe. It also belongs on the shortlist for a Fellow station where the controls and display are part of the appeal.
Skip it if your existing scale reliably weighs coffee and water and you are comfortable calculating a ratio. A basic scale plus a phone timer may already do everything you need. Also skip it as a dedicated espresso drip-tray scale: choose a product explicitly intended for that wet environment and check its dimensions against your machine.
Three modes, three different jobs
Fellow lists Brew Assist, Timer, and Weight modes. Brew Assist guides you toward the chosen water target; Timer mode displays time alongside weight; Weight mode handles ordinary weighing. The manufacturer lists a 2,500 g maximum load, 0.1 g readability, a rechargeable USB-C battery, and a footprint of 177 × 150 × 33 mm. See the current Tally specifications.
Choose the mode that matches your task rather than treating the assisted mode as mandatory. If you already have a fixed recipe with staged pours, time and weight together may be enough. If you weigh a bag of beans or prepare ingredients, ordinary weighing avoids unnecessary brewing steps.
What Brew Assist does not decide
The scale can guide your water amount, but it does not choose the best grind, temperature, beans, or pouring technique for you. A ratio is a starting point for taste. For example, a 1:16 ratio means 20 g of coffee calls for 320 g of brew water; a 30 g dose calls for 480 g. Those are arithmetic examples, not universal recipes or guaranteed final beverage volumes.
Some water remains in the grounds, so the water you pour is different from the coffee you eventually drink. Use the same convention when recording experiments. Changing your coffee dose without preserving the ratio is an easy way to make a familiar cup unexpectedly weak or strong.
After a brew, write down how it tasted. If it needs adjustment, change one variable and repeat. The scale is useful because it makes that process reproducible. Our bitter-coffee troubleshooting guide helps you investigate factors beyond water quantity.
Capacity includes the whole load
Before brewing, consider the combined weight of your server, dripper, grounds, and water. Taring the display does not remove the physical weight from the load cell. A heavy vessel can use much of the available capacity before you pour anything. Do not exceed Fellow’s maximum load, and make sure the vessel sits stably without touching another surface.
Place the scale on a flat, stable counter. A tray that flexes, a vessel leaning on the wall, or contact with a kettle cord can interfere with the usefulness of your readings. Fellow says a stable environment is required for accurate measurement. Read the precision and operating guidance.
The important espresso limitation
Fellow permits weighing espresso grounds in a portafilter but recommends against using Tally directly in a machine’s drip tray. The scale is water-resistant, not waterproof, and its exposed USB-C port should not admit water. That manufacturer advice is more useful than broad retailer language suggesting it is suitable for every espresso task. Read Fellow’s espresso-use warning.
If your main goal is measuring liquid espresso yield under the group head, this is a reason to choose another scale. If you just need to dose beans on a dry counter before grinding, that is a different task. Buy for the actual placement and workflow.
Cleaning, charging, and transport
Clean the scale with a damp non-abrasive cloth, turn it off and unplug it first, and follow Fellow’s instructions for removing the pan. Do not immerse it or put its components in the dishwasher. Read the cleaning guide.
Save the packaging and transport shims. Fellow’s unboxing instructions explain that the shims protect the load cell during transport and need removal before first use. If you intend to travel with the scale, follow the repacking instructions rather than throwing it loose in a bag. See what comes in the box.
Verdict
- Pros: ratio guidance, timer and weight together, rechargeable design, and clear separate modes for brewing and general weighing.
- Limitations: premium cost, no independent performance tests in this review, capacity includes your equipment, and it is unsuitable for a wet espresso drip tray.
Choose Tally if the assisted pour-over workflow solves a real annoyance. If you prefer a simpler routine, spend less on the scale and put the difference toward beans or a grinder. Our Opus 2 review covers the grinder decision; our Stagg EKG Pro review covers the kettle.
