NextLevel Pulsar

Scott Rao demonstrates this pour-over technique on a Kalita Wave; here it is adapted to the Pulsar. Boiling water, a 45-second pre-wet, and two measured pours from a constant height. The no-bypass brewer channels every addition through the bed, supporting a sweet, jammy, juicy cup with high extraction and clear fruit.

Notes

Saturate evenly during the 45-second pre-wet — a gentle spin and a dig into any dry pockets. Then pour in two steady streams from a constant height rather than a wavering one, staying just below the point where the water splashes. Treat total drawdown as the grind cue: if it ends before 3.5 min, grind finer; if it exceeds 4.5 min, grind coarser. Keep water at 100°C.
