Automated Pour-Over Coffee

Pro tips

• Use the pre-wet function every brew—it removes paper taste and ensures even water distribution through the grounds.
• Experiment with the app's customizable variables (water volume, temperature, flow rate, pour pattern) and save successful recipes for consistency.
• Place your mug on the scale before starting to monitor real-time brew weight and ensure you hit your target volume.
• For larger batches, the flat-bottom filter basket and glass carafe reduce brew time and simplify scaling compared to multiple single servings.

Equipment

Cosori Juni automated pour-over machine · cone coffee filter · flat-bottom coffee filter · glass dripper · glass carafe · built-in scale

Can I brew different batch sizes with the Cosori Juni?

Yes. Use the cone dripper for single servings (320 ml shown here), or swap to the larger flat-bottom filter basket with a glass carafe for larger batches.

Do I need the smartphone app or can I use machine controls?

The machine has both built-in controls and a companion smartphone app; you can select or create brew recipes using either method.

What coffee grind size should I use?

Medium-grind coffee is recommended, as shown in this recipe with 20 g per 320 ml water.

Why pre-wet the filter before adding coffee?

Pre-wetting rinses the paper filter to remove paper dust, ensure even saturation, and stabilize the filter in the dripper before adding grounds.

Can I reuse the cone and flat-bottom filters?

Cone and flat-bottom filters are typically single-use paper filters; replace them for each brew to avoid flavor carryover.
