## Abstract Stir bar sorptive extraction‐liquid desorption (SBSE‐LD) has been applied as an efficient sample preparation method for the analysis of beer bitter acids. Extracts free of almost all interfering compounds were obtained, allowing simultaneous analysis of iso‐α‐acids and reduced iso‐α‐aci
