The properties of new Czechoslovak varieties and clones of hops have been evaluated by comparing pilot brewing and applying technological, analytic and organoleptic criteria. Hops of the 1965 harvest were used in the described experimental work and differenciated hopping permitted to elaborate an accurate balance of bitter substances released from hops into beer the amount of such substances being a reliable indicator of the hopping efficiency of the compared sorts. The results confirm that the clone No. 72 maintains its supremacy. Very promising is the clone No. 1118 and varieties Siřem and SM 50/239.(In Czech, English summary only)

The author evaluates the methods used at present in calculating the capacity of bottle washers, bottle washing lines and shops and presents a new, more objective method, based upon adjusting the capacity to maximum seasonal peaks and variations in individual months. Nomograms accompanying the article permit to find the capacity which must be met by the lines to be installed, as well as check the performance of existing insllations.(In Czech, English summary only)

The author compares two methods of utilizing ethyl alcohol present in fermented sewage water from yeast plants, viz. distillation and use in torula plants for increasing the yield of biologic substance of food yeast. The results of experiments indicate that processing in torula plants offers certain advantages only when the sewage contains a higher percentage of alcohol.(In Czech, English summary only)
Chemical method of cleaning bottle washing machines.Peer-reviewed article

Kvasny Prum. 1966; 12(9): 208-210 | DOI: 10.18832/kp1966036
The article deals with a new well proven method of chemical cleaning bottle washing machines requiring removal of sediments and scale from hard water. The method is based on the use of acids simultaneously with efficient inhibitors preventing corrosion of metals. Cleaned surfaces should be protected by subsequent phosphatization.(In Czech, English summary only)
