Faster Coffee Analysis for Consistent Roasting and Better Margins
For coffee roasters, consistency isn’t just about flavour - it directly impacts cost, efficiency, and product quality. Small variations in moisture or caffeine content can affect roasting performance, energy use, and the final cup profile.

But traditional analytical methods used to measure these parameters can slow everything down.
Techniques like high-performance liquid chromatography (HPLC) and oven-based moisture analysis are reliable - but often require extensive sample preparation, skilled operators, and long turnaround times.
A faster way to monitor coffee quality
Near-infrared spectroscopy (NIRS) offers a rapid, non-destructive alternative for analysing roasted coffee beans - delivering results in seconds with no chemicals or sample prep required.
With the OMNIS NIR Analyzer Solid, both whole and ground coffee samples can be analysed directly, either at-line near the roaster or in a quality control laboratory.
Key parameters, measured instantly
NIRS enables simultaneous analysis of:
- Moisture content
- Caffeine concentration
Using advanced calibration models, strong correlation with established reference methods can be achieved - supporting reliable, routine quality control across different sample types.
Why it matters for roasters
Switching to NIRS can deliver measurable operational benefits:
- Faster decision-making during roasting and production
- Improved batch-to-batch consistency
- Reduced energy consumption through optimized roasting conditions
- No need for chemical reagents or complex workflows
Compared to conventional methods that can take hours - or even longer - NIRS provides near-instant insights that keep production moving.
