The right decisions in brewing and winemaking, based on accurate data

Wine and beer occupy an important place in the history and culture of mankind, reflecting long-standing traditions and significance in various aspects of life.

The wine and brewing industries place high demands on the quality of raw materials and finished products. Controlling the content of various elements in beverages plays a key role in ensuring the stability of taste, aroma and color. Accurate and reliable elemental composition data is the basis for informed decision-making in the production process.

Quality control in the production of wine and beer requires regular analysis of the chemical composition to ensure compliance with international standards. In brewing, nitrogen content is crucial for foam formation, which affects the taste and visual characteristics of the beverage. The standards, ASBC (American Society of Brewing Chemists) and EBC (European Brewing Convention), define the requirements for nitrogen analyses.

In winemaking and brewing laboratories, the Dumas method is used to accurately analyze the nitrogen content of various samples.

The importance of this method is confirmed by standards such as OIV-MA-AS323-02A, which describes the procedure for determining total nitrogen in wines and must. This method is used within the framework of international standards and allows you to ensure high quality products through accurate analysis of chemical compositions.

In winemaking, an important element is the control of sulfur dioxide (E220), which is used as a preservative. The ISO 5522 (Wine, Determination of Sulfur Dioxide) and OIV (International Organization of Vine and Wine) standards regulate the permissible levels of sulfur dioxide in wine. CHNS-O element analyzers and nitrogen/protein analyzers comply with these standards and provide high measurement accuracy. For example, standards:

5

ASBC Beer-31 – “Total Nitrogen by the Dumas Method”

5

EBC Analytica – Nitrogen by Combustion (Dumas Method)

5

OIV-MA-AS323-07A – “Method OIV for the determination of total nitrogen by combustion (Dumas method)”
