The discovery of Swiss researchers about the stable foam in Belgian beer

Swiss researchers from ETH Zurich have unraveled the mystery of stable foam, one of the most famous features of Belgian beer. It turns out that the secret lies not only in the fermentation process but also in the interaction of proteins and polyphenols found in malt and hops. According to scientists, the proteins formed during fermentation create complex complexes with polyphenols. These compounds help form a stable structure around carbon dioxide bubbles, preventing the foam from disappearing quickly. Such foam remains on the surface of the drink longer, preserving the aroma and taste properties of the beer.

The published scientific paper indicates the significance of yeast and fermentation temperature in shaping the chemical composition of beer. Understanding these processes can help brewers worldwide improve the quality of their beverages. It is known that Belgian varieties such as lambic or abbey beer are characterized by dense and long-lasting foam that retains aroma inside and delights connoisseurs with its taste for a long time. From any angle, this discovery is important for brewers and lovers of this drink.

According to inkorr.com: Swiss scientists from ETH Zurich discovered that the secret of stable foam in Belgian beer lies in the interaction of proteins and polyphenols found in malt and hops. This finding could assist brewers in improving the quality of the beverage and bring pleasure to fans of true Belgian beer.

The research of Swiss scientists opens new horizons for the brewing industry, particularly in understanding the complex chemical processes that affect the taste and aroma of beer. This knowledge may serve as a basis for innovations in production, ultimately enhancing the quality and diversity of beer beverages in the global market.
