The pale Pilsener-style lager beers produced on a massive and craft scale were taken to analyse their basic physicochemical properties (alcohol content, pH, haze, real degree of fermentation) and volatile compounds profiles. The research was carried out using a beer analyser equipment and a headspace gas chromatographymass spectrometry method (HS/GC-MS). The findings showed that in terms of physicochemical and flavour attributes, the quality of craft beers differed to a higher degree from the standard Pilsener beer quality than in the case of industrial beers.

W pracy przedstawiono wyniki badań zawartości wybranych pierwiastków w piwie. Celem badań było określenie związku między składem, rodzajem piwa, jego pochodzeniem i rodzajem opakowania a zawartością oznaczanych pierwiastków. Analizę wybranych metali wykonano przy wykorzystaniu techniki optycznej spektrometrii emisyjnej ze wzbudzeniem plazmie sprzężonej indukcyjnie (ICP-OES). Etap przygotowania próbek piw obejmował odgazowanie i mineralizację przy wykorzystaniu 70-proc. kwasu HNO3. Na podstawie uzyskanych wyników badań zaobserwowano, że spośród wszystkich analizowanych pierwiastków dominującymi były makroskładniki (Ca, Mg, Na i K). których głównym źródłem jest woda wykorzystywana w procesie produkcji piwa. W pracy wykazano również, że zły stan techniczny instalacji wykorzystywanej w ciągu technologicznym może przełożyć się bezpośrednio na wyższą zawartość żelaza i pogorszenie walorów smakowo-zapachowych piwa.

The paper presents the results of research on the content of selected elements in beer. The aim of the study was to determine the relationship between the composition, type of beer, its origin and type of packaging, and the content of the analyzed elements. Metal analysis was performed using the inductively coupled plasma optical emission spectrometry (ICP-OES). The beer sample preparation stage involved degassing and mineralization using the 70% HNO3 acid. Based on the obtained results, it has been observed that of all the analyzed elements, the dominant ones are macronutrients (Ca, Mg, Na and K), whose main source is water used in the beer production process. The paper have also demonstrated that the poor technical condition of the installation used in the technological process can translate directly into higher iron content and deterioration of the taste and aroma of beer.

The objective of the paper is to analyze the cooperation in craft beer manufacturing in Poland and to identify the specificity of this phenomenon from the perspective of enterprise management. The sales of craft beers in Poland are growing rapidly. Craft beers have about a 0.5% share in the total beer sales value in Poland. The popular practice in the industry is contract brewing. It is an interesting phenomenon in the field of cooperation of enterprises which can be classified and analyzed as a form of: economic cooperation (generally), production cooperation, outsourcing, network and virtual organization and also coopetition. It is a specific business model. Contract brewing is a complex problem the specificity of which emerges on several levels. Firstly, there is a special way to emerge in the market of craft beers, even while not possessing significant funds by the entrepreneur. Secondly, it is a form of cooperation in the field of production which unites efforts on the side of both the customer and the contractor since it is not limited to normal outsourcing of production to an external entity but involves physical production capacity of the contractor and technological know-how of both cooperation parties. Thirdly, it is firmly embedded in human relationships. Fourthly, it can generate coopetitive relations since the brewery accepting the order may conduct its own activity related to production and sales of beer under its own brand.
