In the aim to improve the filtration process in the beer manufacture, a study on the beer turbidity have been made using two different techniques: nephelometry and V-UV spectrometry. Even though the former is the most commonly used, we propose the use of V-UV spectrometry since it is possible to follow the performace - of all the filtration line, not only in a punctual way but in a - wide range of wavelenghts. From the results of this work we deduce that V-UV spectrometry offers a better quality of results than nephelometry, being more useful in rutin periodic controls.
