Learn how to get the most from your Nanopresso Barista Kit with step-by-step tips for double espresso, proper dosing, and travel-friendly brewing.

Quick answer

The Nanopresso Barista Kit lets you brew double espresso up to 120ml with 18 bar pressure. Follow these six steps to avoid common mistakes and get café-quality shots anywhere.

Why the Barista Kit matters for portable espresso

The Barista Kit expands your Nanopresso's capacity from a single to a double espresso (16 grams of ground coffee). With 18 bar extraction, it outperforms many home machines. But the larger basket means you need to adjust your grind and tamping technique to avoid under-extraction or channeling.

How to use the Nanopresso Barista Kit: step-by-step

1. Grind fine, but not too fine: Use a burr grinder set to a fine espresso grind (similar to table salt). Too fine will clog the basket; too coarse will produce watery espresso. Test with a small dose first—if extraction takes longer than 30 seconds, grind coarser.
2. Dose 16 grams evenly: Fill the larger Barista Kit basket with 16 grams of coffee. Level the grounds with a finger or distribution tool to avoid uneven extraction. Don't overfill—the basket should have a slight gap after tamping for the screen to fit.
3. Tamp with firm, even pressure: Use the included tamper to press down until the coffee is compact and level. Aim for about 15 kg of force—consistent pressure is key. A tilted tamp causes channeling; check the puck surface is flat before locking.
4. Attach the basket and pump system: Lock the filled basket into the Nanopresso head, then attach the pump arm. Ensure the seal is snug to prevent pressure loss. If you feel air escaping during pumping, re-check the seal and basket fit.
5. Pump slowly and steadily: Pump the handle at a steady pace—about one pump per second. Slow pumping builds pressure gradually for better crema. Rushing can cause low pressure; if you see no crema, pump more gently.
6. Stop at 60-120ml output: Stop pumping when you reach your desired volume—60ml for a ristretto, up to 120ml for a lungo. The Barista Kit handles both. Over-extracting past 120ml can make the shot bitter; stop early for sweeter results.
