Sweetness Focus

NextLevel Pulsar Nextlevel by Jonathan Gagné

Jonathan Gagné's Coffee ad Astra approach for the Pulsar is built around no-bypass extraction and careful flow control. Its cup goal is concentrated sweetness with jammy, juicy fruit while retaining enough clarity to separate ripe flavor notes.

Notes

Pre-wet by filling above the base ridges, placing the dry filter, and draining before adding coffee. For every additional 5g of coffee, coarsen by about 50um to preserve flow. Dial the valve and grind together: avoid a stalled bed while keeping extraction high enough for juicy sweetness.
