<p>The coffee industry is grappling with challenges in quality assessment and characterization due to rising demand for high-quality coffee and the complexity of its supply chain. This study examines recent trends in coffee quality assessment techniques through a systematic literature review and bibliometric analysis of publications from the past decade (2015–2024). After going through several selection criteria, the Scopus database found 100 journal articles published between 2015 and 2024, and were identified and submitted for bibliometric analysis. The analysis found an upward annual growth rate of 27.12% in this research subject. Several measurement principles have been identified, including physical, chemical, spectral, and other characteristics. Recent trends identified four key objectives of using these technologies, such as assessment of roasting degree and brewing profile, authentication, detection of chemical components, and identifying adulterants, defects, and toxins. Although many techniques have been developed, their use is not yet widespread and applicable. Nevertheless, rapid advances in technology have created new prospects for more applicable developments. Future research should focus on cost-effective sensor development with high precision based on combined principles (e.g., spectral and physical) due to its high potential applications, rapid and nondestructive manner.</p>
