In this experiment RLU (relative light units) values of water of the filling stations of six wineries were examined before and after cleaning. For measurements of the ATP amounts an instrument from Kikkoman was used. This technique is very well suited for cleaning inspection. It shows quickly if the surface of filling station or water is clean or dirty. In this experiment rinse water of six wineries has been tested with LuciPac Pen (cotton swab for surface inspection) and LuciPac Pen-Aqua (special pens for water analysis). For most of the samples, the ATP measurements were made immediately after sample collection, with the remaining samples, the RLU values were taken only in the laboratory. The average ATP values of tap waters are approximately 20 RLU in Austria. This value agrees well with the water value of the Education and Research Center of Viticulture and Pomology in Klosterneuburg. The RLU amount was around 15 RLU. In wineries where well water was used as process water, dangerous germs were isolated. These bacteria were identified by Vitek 2 compact as soil bacteria of the family Pseudomonaceae.
