After about fifteen years a study was carried out to determine the variation in results of the N‐nitrosodimethylamine (NDMA) determination in beer and malt carried out in different laboratories, in order to obtain an overall view of the precision of the various methods used. Two collaborative trials were carried out by the EBC Analysis Committee during 1998. Repeatability values (r 95 ) for beer in the range of 0.09 ÷ 0.13 and for malt 0.33 ÷ 0.42 were found. Reproducibility values (R 95 ) for beer in the range of 0.45 ÷ 0.54 and for malt 0.65 ÷ 4.08 were obtained.
