Further finished stage of the brewery reconstruction is described. The following new equipments were installed: the filling of plus KEG, the brew houses for 9 t grist that make the satisfactory capacity 36 000 bottles per hour that permits an application on the new kind of packing. Also some experiences from the first operation period of the new plants are discussed.(In Czech, English summary only)

Significant biochemical properties of 17 production strains of wine-making yeasts were observed and evaluated. From the standpoint of respiratory properties the highest RQ value was achieved with our strain S. cerevisiae 2C. Satisfactory results have also been obtained with the alcohol resistant strain S. cerevisiae 6C being isolated by authors. The metabolic activity of inoculating material of the individual strains is detected by acidification properties. The highest change of pH in the mixture of glucose and fructose was achieved with the comparative strain S. cerevisiae 13 RVV after 20 min (DpH20 = 1,63). The results...
