How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Currently, the application of the dry hopping process is a new technology. This method of introducing hops allows you to preserve unstable aromatic oils. The dry hopping process means the addition of hop products at the fermentation stage of the fermentation chine or kegs after the fermentation process is completed. The dry hopping technology does not give the beer a bitter taste, but as a result of its use, it allows you to preserve volatile unstable aromatic oils that evaporate during cooking: monoterpenes-myrcene , diterpenes-dimircene, sexwiterpenes-β-corpofyllene, etc. Beer prepared using this technology is characterized by a rich aroma of hops, which is not present in traditional brewing technology. Based on the production tasting quality assessment, sensory profiles and physico-chemical parameters of drinks with different concentrations of Goldings hops were determined, in particular, the content of the extract, pH, the content of bitter substances, color, diacetyl content, alcohol content, the degree of fermentation, and according to the results of the profilogram analysis, the optimal dose of hops administration was 29 g/dal.
