The particle size of coffee grounds greatly affects the flavour of brewed coffee. If the coffee grind is fine then a powerful espresso-like flavor may be produced, as many of the complex organic components within the coffee bean are released during brewing. If the coffee grind is coarse then a smoother flavor may be obtained for the final brew.
Coffee analysis methods
The traditional method for coffee particle size and size distribution measurement is sieving. However, sieve measurements are slow and do not correctly assess the percentage of fine material within the coffee grind, leading to variations in the brew strength. Laser diffraction particle size analysis is a rapid alternative to sieving, providing:
- Automated measurement of different coffee grind particle size distributions using one simple measurement workflow,
- Reduced time to results during routine QC operations, enabling improved grind consistency,
- In-process measurements for real-time grind quality feedback, providing reduced production costs by avoiding over-grinding.
Our instrumentation
Malvern Panalytical provides advanced instruments for comprehensive coffee analysis, ensuring high standards in coffee quality analysis within laboratories:
Insitec Range
Insitec range
Robust, reliable, real-time particle sizing
Insitec offers real-time particle size analysis, crucial for maintaining consistent quality and optimizing coffee milling processes.
Mastersizer 3000+ Range
Mastersizer range
The smartest way to measure particle size
The Mastersizer 3000+ range delivers precise particle size distribution measurements, essential for controlling grind size and achieving uniform extraction.
The particle distribution of coffee is very polydisperse, so in order to obtain consistent results a large amount of material is required.
The Aero Funnel sample feeder option allows the measurement of approximately 15 g of coffee so a representative sample can be measured. It also comes with a coated tray reducing the amount of material stuck on during measurement.
