Beer yeast is the specific strain of yeast intentionally added to wort (unfermented beer) during the beer-making process. It is required in fermentation, converting sugars in the wort into alcohol and carbon dioxide, resulting in beer. Beer yeast does contain some nutrients, but its primary role is fermentation.
Beer yeast contains a high concentration of purines, which are organic compounds that break down into uric acid. This is the main reason why beer and alcoholic beverages are considered major gout triggers.
Note: Beer yeast and brewer’s yeast are not the same. Brewer’s yeast is a nutritional supplement derived from the byproduct of beer brewing, while beer yeast is a specific strain of yeast used in the fermentation process of making beer.
