Benefit from more than 2,200 state-of-the-art applications, conducted with the most accurate and efficient lab technology.
The production and quality control of wine requires precise and reliable analyzers
The wine industry is subject to strict regulations on the quality and safety of its products. This is not without reason. If contaminated wine reaches the retail market, the consequences can be dire – not just for consumers.
Metrohm offers top-quality analytical instruments, application expertise, and first-class, on-site service to enable and support the production and quality control of your wines.
Metrohm actively participates in the development of standards for testing and quality control of wine through our involvement in AOAC and ISO method development.

- WP-065Simplified sulfite determination in foods and beverages using ion chromatography
Sulfites are well-known additives in foods and beverages used to extend shelf life and preserve colors. Such properties have led to the broad usage of sulfites in a range of foodstuffs like fruits, cereals, vegetables, seafood, juices, alcoholic and non-alcoholic (soft) beverages, and in some meat products. The term «sulfites» describes a group of molecules that include sulfur dioxide (SO2) and chemically related molecules like sodium sulfite (Na2SO3), sodium bisulfite (NaHSO3), or sodium metabisulfite (Na2S2O5). Sulfite intake has been correlated with several adverse reactions, and therefore sulfites are included in the FAO/WHO Codex Alimentarius list. Labelling sulfite content in foods and beverages is necessary when the total concentration exceeds 10 mg/kg. Metrohm ion chromatography allows the reliable measurement of sulfite in different matrices using either conductivity or amperometric detection. The inclusion of automated sample preparation and cleaning steps with Metrohm instrumentation saves additional analyst time and helps increase sample throughput.
- AN-CS-014Biogenic amines besides other cations in red wine applying a high-pressure gradient
Biogenic amines are released during the winemaking process. In wine, they are present as odorless salts. However, in the mouth their flavor is partially liberated, influencing the appearance for the wine taste. Besides this, biogenic amines have been related to lack of hygiene or poor manufacturing practices. The biogenic amines are determined applying suppressed cation chromatography.
