Coffee Research Lab
Independent Studies on Extraction Science & Brewing Consistency
The Vihi Coffee Research Lab operates independently to explore the physics, chemistry, and geometry behind manual brewing. Led by a Royal College of Art PhD graduate, our team combines industrial design expertise with rigorous scientific methodology to solve real brewing consistency problems.
Unlike marketing-driven “research,” our studies are data-first. We publish our methodologies, share raw data when possible, and welcome peer review from the coffee community.
Research Focus Areas
Filter Geometry
How paper structure affects flow dynamics and extraction uniformity
Extraction Science
TDS, EY%, and flavor compound analysis across brewing variables
Brewer Comparison
Side-by-side testing of flat-bottom vs cone drippers
Consistency Metrics
Identifying and controlling variables for repeatable results

Research Methodology
Every experiment in our lab follows rigorous protocols to ensure reproducibility and accuracy:
- Controlled Variables: Temperature, grind size, and water chemistry are standardized using laboratory-grade equipment
- Measurement Tools: VST Coffee Refractometer for TDS, precision scales (0.01g), and FLIR thermal imaging
- Statistical Rigor: Minimum n=12 samples per condition, with outlier detection and confidence intervals
- Blind Protocols: Taste evaluations use double-blind methodology to eliminate bias
- Open Data: Raw data and methodologies available for peer review upon request
