The technological quality of brewing barley was evaluated with respect to the effect of potassium content in a soil, an inorganic fertilizer and an application of the bioregulator Sencor 70 WP. It was found that potassium in the concentration above 90 - 110 mg.kg-1 in the soil, which was introduced as a fertilizer or due to water regime, can negatively affect the technological quality of brewing barley. The application of bioregulator Sencor 70 WP had a positive effect on the growth as well as on the mechanical and chemical parameters of brewing barley.(In Slovak, English summary only)

Different fermentation stimulators were tested on the growth and fermentation activity of some wine yeast species and strains. The preparation of Botrytis cinerea had the most pregnant activation influence on the growth and the first phase of fermentation of must. A more profond fermentation with less residual sugar and lower volatile acid concentration in the wines were achieved. Thiamine shows only a slight stimulating influence, while (NH4)3PO4 and urea had no positive influence at all.(In Slovak, English summary only)
Turbidity of spirits caused by the corrosion of the inner surface of long-term stored of empty bottles.Peer-reviewed article

Kvasny Prum. 1985; 31(4): 80-83 | DOI: 10.18832/kp1985014
The article elucidates the origln of a turbidity in spirits which Is caused by the corrosion of tbe inner surface of longterm stored of empty bottles. The factor Influencing an extent of this corrosion (such as time of storage, composition of glass used etc.) are described. In order to reduce the quantity of spirits that are deteriorated In this way some provisions are proposed.

Two new types of mashines (SxM 150 and SxM 200) for a mixing of mineral water were with syrup or for a carbonizing of mineral water were developed in engineering works in Chotěboř. An adjustable mixing ratio of syrup and mineral water is in a range of 1 : 4 to 1 : 100, outputs per hour with the mixing ratio of 1 : 4 are 15,4 m3 or 20,5 m3 in both types of mashines, respectively.(In Czech, English summary only)
