Given the scenario of buckwheat cultivation in Brazil, the research was developed evaluating its insertion in beer production as adjunct. The samples of interest were made with 55% (w/w) barley malt and 45% (w/w) buckwheat malt (45BWM), referenced to 100% Pilsen malt beer (AM). The results showed that the buckwheat malt wort had a 96.27% dry base extract, equivalent to the standard result. It also showed that glucose content increased 3 times, while the maltose and maltotriose have balances proportional. The use of buckwheat malt raised the protein content in more than 89%, which is not seen from the use of other adjuncts and showed greater colloidal stability during the storage period, a factor associated with a 4-fold reduction of gluten content. Similar aspects regarding foam and turbidity pattern, although subtle differences in aromatic profile and flavors were present. Nevertheless, these factors show that is possible to use buckwheat as an adjunct in a Pilsen beer. The remaining sugars content gave a perspective on the metabolism of yeast during fermentation and the identification of some compounds by HPLC-MS was also able to demonstrate how buckwheat malt affected yeast metabolism due to wort composition.

highly hopped and dry hopped beer production and consumption has increased steadily for the last twenty years, following the rise of craft breweries in the United States of America and the trend they set over the world. This overuse of hops offers some environmental, technological, and economic challenges for the beer industry. Researchers have been studying several ways to make beer more ecofriendly by promoting reuse of spent hops and increasing extraction yields. Dry hopping is a sizedependent process, making it feasible for craft breweries with their small scale production, but quite a challenge for larger tanks and breweries. Based on the literature and industrial experience from brewers, the aim of this research was to analyze and discuss different dry hopping methodologies for the brewing industry and how the parameters affect the final product. In order to shed light on this trending topic and to better aid brewers in choosing the most suitable, efficient, and environmentalfriendly dry hopping process for their brewery, this work approaches the main variables that promote aroma transfer from hops into beer and how to optimize it.

Brazil imports about 60% of all the malt used by the brewing industry which is spread throughout the country. Even though it is an agricultural country, only a small portion of the barley production has the characteristics to produce barley malt for brewing. Seeking supply to the ever-growing demand and reducing the dependency on other countries and logistic costs, malting industries and genetic enhancement companies endeavor to adapt barley to the Brazilian Savannah conditions. For the barley to be malted, it is crucial to develop cultivars with the necessary malting qualities and adapted to the region and with good yield. Considering the importance of protein to the brewing process, four protein quantification methods were compared: combustion methods-carbon, hydrogen and nitrogen elemental analysis and Dumas-and digestion ones-Kjeldahl and flux injection analysis (FIA). The methodologies tested showed good correlations (higher than 0.881) and variations were associated with matrix complexity. All protein quantification methods were satisfactory from an agronomic perspective. Yet, we recommend the combustion ones as they generate fewer residues and results are ready in up to 6 minutes. Therefore, they are the most suited for barley and malt analysis considering lab routine.

O lúpulo é o insumo utilizado na fabricação de cerveja responsável por aromas e pelo amargor da bebida. No Brasil, essa matéria-prima é importada quase que em sua totalidade. Essa planta, habituada a regiões de clima específico, está sendo cultivada em solo brasileiro e obtendo resultados promissores. Em função disso, o presente artigo buscou realizar uma prospecção tecnológica, por meio de uma metodologia qualitativa exploratória, sobre o que está sendo estudado e desenvolvido sobre lúpulo e sua utilização no processo cervejeiro nos últimos 20 anos. Sabe-se que, a partir do momento em que houver a comercialização de lúpulo nacional, novas tecnologias e processos serão necessários para sua manufatura. A pesquisa revelou uma tendência de países com maior produção de lúpulo ou cerveja a investirem mais em pesquisa e desenvolvimento no setor. Além do mais, foram identificados entraves para a inserção apropriada do lúpulo cultivado em território nacional para ser utilizado pelas cervejarias.

A cerveja é legalmente definida como a bebida obtida pela fermentação do mosto cervejeiro obtido a partir do malte de cevada e adicionado de lúpulo, além disso adjuntos cervejeiros podem ser empregados na proporção de até 45% de seu extrato primitivo. Apesar do crescimento da produção cervejeira, a importação de malte ao Brasil se manteve praticamente inalterada. A metodologia empregada foi a exploratória a fim de avaliar os métodos e propor uma análise que possa auxiliar na fiscalização da proporção do uso de adjuntos na produção de cerveja. O controle da substituição pode ser realizado por análises laboratoriais, apesar de no momento, não haverem métodos desenvolvidos para tal fim. As diversas metodologias de espectrometria de massas se apresentam promissoras no controle laboratorial, podendo ser utilizadas em conjunto com outras técnicas.
