Varia AKU espresso coffee scale
You place the cup on the scale, lock in the portafilter and start the shot – the scale tares automatically, the timer runs along, and on the bright LED display you see the weight rise in real time. No guessing, no second device for timing. It's exactly this workflow that makes the difference between a random shot and a repeatable one.

What makes the AKU special
The AKU is designed as a working scale for home and café use. It offers automatic tare and timer modes for espresso, plus a fully manual mode in which you control every variable yourself. The high-quality load cell measures to 0.1 g across the entire range, read on a clear 9-digit LED display. The housing is made from a cast alloy and CNC-machined to a 0.02 mm tolerance – stable, durable and insensitive to heat. Rated IPX5, the AKU is protected against water jets from any angle.

What goes with it
The AKU works with any portafilter machine, for example from La Marzocco, Rocket or ECM, and goes with every grinder from the Varia collection. If you're looking for a particularly flat travel scale, the AKU Mini is the slimmer sister; if you need more capacity and a colour display, the AKU PRO is worth a look.

Frequently asked questions
Is the AKU suitable for espresso and filter?
Yes. For espresso there's auto-tare and timer, for everything else the manual mode. The 0.1 g accuracy is enough for both brewing methods.
Does the AKU fit on my machine's drip tray?
On many machines, yes. If it needs to be particularly flat, the AKU Mini at 13 mm high is the better choice.
Is the scale protected against water?
Yes, to IPX5 against water jets from any angle – robust enough for everyday café use.
Roastery tip
If you want reproducible shots, weigh both dose and yield. Set a ratio of 1:2 as your starting point – 18 g of coffee, 36 g in the glass – and feel your way towards your taste from there. It's not a law, just a good start. That's our recommendation, one of many.
