AcaiaPearl.
The verdict in one line: Acaia's own spec sheet lists a 2000g capacity, 0.1g readability, and a built-in Auto-Start Timer Mode, which together cover the 15g/250g pour-over dose and the 18g/210g AeroPress dose our guides call for, and the digital-scale-with-timer both guides list as required gear.

Every requirement below comes straight out of our own brew guides. Each segment is one requirement; hover or focus any segment to see the exact check it stands for. Lit means the published spec meets the recipe. We do not light what we cannot cite.

For you if
- You want one scale to cover both methods: Acaia's 2000g capacity clears our guide's 250g pour-over yield and 210g AeroPress yield with plenty of headroom.
- You dose to the gram: Acaia's own 0.1g readability comfortably resolves the 15g pour-over dose and 18g AeroPress dose our guides call for.
- You want the scale-and-timer combo both guides list as separate required gear built into one unit: Acaia's spec sheet names a built-in Auto-Start Timer Mode rather than a separate stopwatch.
Not for you if
- You specifically want the Pearl Model S: retailers list that as a separate product from the standard Pearl this dossier checks.
- You need a stated water or splash resistance rating: Acaia's own product page lists none for the Pearl.
- You want a numeric flow-rate spec to plan a pour by: Acaia's page names a Flow Rate Indicator feature but states no figure, and neither of our guides sets a numeric flow-rate target to check it against.

Questions, answered plainly

Acaia Pearl against our numbers
The Acaia Pearl is a coffee scale, and both methods it’s rated for on this site, our pour-over guide and our AeroPress guide, list a digital scale with a timer as required gear rather than optional extras. Acaia’s own product page states a 2000 g maximum capacity and 0.1 g readability, and names a built-in “Auto-Start Timer Mode” among the Pearl’s brewing modes, folding the scale-and-timer requirement into a single unit.
Both guides’ numbers sit comfortably inside that capacity and resolution. Our pour-over guide doses 15 g of coffee against a 250 g pour; our AeroPress guide doses 18 g against a 210 g pour. Acaia’s stated 0.1 g readability resolves either dose cleanly, and the 2000 g capacity clears either yield target with room to scale up a batch. Acaia’s page also names a Flow Rate Indicator, but states no numeric threshold, and neither guide sets a flow-rate figure to check it against, so that feature sits outside what this dossier can verify.
One naming note is worth flagging. Acaia’s own site and the Seattle Coffee Gear listing both name a separate “Pearl Model S” as a distinct product from the standard Pearl. This dossier checks the standard Pearl specifically, at the 2000 g capacity and 0.1 g readability its own page states, not that other listing.
FAQ
What’s the maximum weight the Acaia Pearl can measure?
Acaia’s own product page states a 2000 g (70.55 oz) maximum capacity, well above both our pour-over guide’s 250 g yield target and our AeroPress guide’s 210 g yield target.
Is the Acaia Pearl precise enough for a 15g or 18g coffee dose?
Yes. Acaia states 0.1 g readability, which resolves both our pour-over guide’s 15 g dose and our AeroPress guide’s 18 g dose to a tenth of a gram.
Does the Acaia Pearl have a built-in timer?
Yes. Acaia’s own page lists an “Auto-Start Timer Mode” among the Pearl’s brewing modes, alongside a Dual Display Mode and Beverage Mode, meeting the digital-scale-with-timer requirement both our pour-over and AeroPress guides list as separate required gear.
What’s included in the box?
Acaia’s product page lists one Pearl coffee scale, one heat-resistant pad, and one USB Type-C charger cable.
Is the Amazon listing the same Pearl this dossier checks?
The canonical Amazon listing title reads “Pearl Scale by Acaia,” matching the product name on Acaia’s own Pearl product page. Amazon’s page did not render full box-contents bullets on fetch, so treat that specific detail as unconfirmed.
Sources & data
- Acaia, Pearl product pagePrimary manufacturer source, fetched 2026-09-11. Supplied capacity, readability, dimensions, product weight, battery life, connectivity, charging, display, included items, the Auto-Start Timer Mode wording, and the Flow Rate Indicator wording.
- Seattle Coffee Gear, Acaia Pearl Coffee Scale listingCorroborating specialist retailer listing, fetched 2026-09-11. Confirms this is the Pearl model (the page's warranty text separately names Pearl and Pearl Model S as distinct products) and states matching 0.1g accuracy and a 40-hour battery figure, inside Acaia's own 30-40 hour range. Not used for any check cell since it added no new number beyond the manufacturer page.
- Amazon, Pearl Scale by Acaia listingFetched 2026-09-11. Canonical title reads 'Pearl Scale by Acaia,' matching the manufacturer's Pearl product name, not the Pearl Model S line. Amazon's own page rendered mostly script content on fetch, so box-contents bullets could not be quoted directly; no bundle language appeared in the title or search snippets.
