Özet

A case study is presented for construction of the quality control charts with suboptimum size samples obtained in a commercial brewery after measuring total acidity, apparent extract and pH of the wort; alcohol, real extract, carbon dioxide total acidity and pH of the bottled beer. Logarithmic transformation of the data was employed to construct the quality control charts, and centering of the data between the specification limits was assessed by means of the process capability index values.
