The NextLevel Pulsar Mini is the single-cup version of the Pulsar — the same no-bypass geometry, valve and dispersion cap in a smaller chamber optimised for doses between {{12|g|mass}} and {{20|g|mass}}. Every part is manufactured in the United States.
Two features define how it brews. The dispersion cap spreads each pour evenly over the whole bed, so the water wets the grounds uniformly instead of drilling a channel. The valve at the base lets you stop the flow completely — turning the Mini into an immersion brewer — or open it to any partial rate, so you can separate an immersion phase from a percolation phase inside one recipe. Because no water slips down the wall and bypasses the bed, strength is set by brew ratio alone.
The smaller chamber means a deeper bed for a given dose, so contact time runs longer than on the full Pulsar — NextLevel's own guidance is that deeper beds need more time. It uses NextLevel's own paper filters and suits single-cup ratios from about 1:15 to 1:20. Close the valve for a controlled immersion bloom, drain it, then open it part-way for a percolation finish — the move most of these recipes are built around.
