The Subminimal SubScale is an espresso dosing cup with a scale built into the base, accurate to 0.1 grams. The LED display is invisible until you tap the capacitive touch surface, so on the counter it reads as a plain matte black cup rather than a gadget. It holds 60g of beans or 120ml of liquid, recharges over USB-C on a 400mAh battery instead of coin cells, and is IPX-4 splash resistant with auto shut-off. The body is Tritan, which is food-safe and handles hot espresso and cold brew equally. The practical win is workflow: you weigh your dose in the same vessel you pour into the grinder, which removes a separate scale from the counter entirely. Best fit: home espresso setups where counter space is tight and the setup is on display.

Frequently asked questions
Does it have a timer for tracking espresso extraction?
No. It weighs dose accurately but has no timer, so it is best for weighing beans before and after grinding rather than replacing a full brew scale under the cup.
How much can it hold?
60 grams of coffee beans, or 120ml of liquid. That covers a double or triple shot dose comfortably.
Can I actually drink out of it?
Yes. The body is food-safe Tritan rated for hot espresso and cold brews, and it is IPX-4 splash resistant.
How does it charge?
USB-C, into a 400mAh internal battery. There are no replaceable batteries to buy.
Is it dishwasher safe?
No. It contains electronics, so rinse and wipe it rather than putting it in the dishwasher.
