NextLevel Brewer Co is a US-based specialty coffee equipment brand. Their drippers — the Pulsar, the Pulsar Mini, and the earlier LVL-10 — are built around a "no-bypass" geometry: water is forced to pass through the coffee bed rather than slipping down the wall, which is the mechanism a conventional V60 leaks extraction through. All components are manufactured in the United States. The Pulsar's geometry was developed in collaboration with Jonathan Gagné, the astrophysicist behind The Physics of Filter Coffee.
Models in this family
- NextLevel LVL-10 — the predecessor. A flat-bottom dripper with a sealed valve, used as a hybrid immersion-or-percolation device.
- NextLevel Pulsar — the current flagship. A conical no-bypass dripper with a perforated diffusion chamber on top and a controllable valve at the bottom. The diffuser spreads each pour evenly across the bed; the valve regulates drawdown rate and lets you pause flow for an immersion stage.
- NextLevel Pulsar Mini — smaller chamber, same mechanism. Single-cup capacity.
The diffuser-plus-valve design lets you deliberately separate immersion and percolation stages within the same recipe — closing the valve while you bloom, then opening it to drain. That kind of explicit phase control is what most no-bypass recipes exploit.
How the NextLevel brews
The valve at the bottom restricts flow even with the kettle running, so the chamber holds a slurry of coffee and water that the diffusion chamber tops up evenly. Closing the valve fully turns the Pulsar into an immersion brewer; opening it fully turns it into a fast pour-over. Most published recipes set a partial flow rate that targets a specific drawdown time. Because the diffuser spreads water across the whole bed, channeling is rare and pour technique matters less than with a V60.
What NextLevel recipes in this collection share
Recipes typically combine a closed-valve bloom phase with one or two open-valve pour phases. Typical parameter ranges:
- Ratio: 1:15 to 1:17
- Water temperature: 92 to 96 °C
- Grind: medium to medium-fine (slightly coarser than V60)
- Total brew time: 3:00 to 4:30
Choose a NextLevel dripper when you want explicit control over immersion vs. percolation in a single device, when channeling is your repeated bug with a V60, or when you want a no-bypass brewer with the support tooling and recipes Jonathan Gagné and the NextLevel team have published.
