Shape the extraction.A brewer designed for precision and experimentation. The Pulsar Brewer by NextLevel is a thoughtfully engineered dripper created in collaboration with astrophysicist and coffee researcher Jonathan Gagné, author of The Physics of Coffee. Built as an evolution of the LVL-10 concept, it introduces a variable-flow-rate valve that expands brewers' approach to bloom, immersion, and percolation. At the heart of the Pulsar is its no-bypass design, ensuring that all brew water interacts directly with the coffee bed rather than escaping along the filter walls. This allows for more controlled strength, clarity, and extraction consistency. The adjustable valve enables longer, more efficient prewetting and steeped blooms, while the dispersion cap promotes uniform saturation across the grounds. What makes the Pulsar especially compelling is its versatility. You can retain water during bloom, experiment with steep-and-release techniques, or create hybrid brews that balance immersion and percolation depending on your recipe. The thermally stable construction also helps maintain higher slurry temperatures, supporting more even extraction throughout the brew cycle. For curious brewers who enjoy dialing in variables and exploring new techniques, the Pulsar offers a precise and adaptable platform that encourages intentional, skill-driven brewing. Why We Chose This We chose the Pulsar for its depth of control and experimental brewer that still feels deliberate and grounded in design. A brewer that rewards curiosity, precision, and a deeper understanding of extraction.
