The NextLevel Pulsar is a no-bypass dripper from the US brand NextLevel Brewer Co, with a geometry developed in collaboration with Jonathan Gagné, the astrophysicist behind The Physics of Filter Coffee. It is moulded from thermal-stable plastic, every part is manufactured in the United States, and it holds about 380 ml — its reference recipe is 20 g of coffee to 340 g of water, a clean 1:17.
Two parts define how it brews. A dispersion cap sits on top and spreads every pour evenly across the whole bed, so the water wets the grounds uniformly instead of drilling a channel — pour technique matters far less than on a V60. A valve at the base gives complete control over flow and agitation: close it and the Pulsar becomes an immersion brewer that holds water through the bloom; open it part-way for a controlled percolation rate, or fully for a fast pour-over. Because no water slips down the wall and bypasses the bed, strength is set by brew ratio alone.
That valve is what most Pulsar recipes are built around — a closed-valve immersion bloom, a drain, then an open-valve pour phase, often clock-referenced ("open to 12 o'clock") for a repeatable flow rate. It uses NextLevel's own paper filters and accepts a metal filter for a more bodied cup. For single-cup brewing there is a smaller sibling, the Pulsar Mini.
