Cause of Flavour
In alcoholic beverages – primarily beer – phenolic is imparted by specific yeasts during fermentation. This can either be by design or by accidents. Certain wheat beer styles use yeasts that are designed to produced very phenolic flavoured beer. This is a desirable flavour and part of the brand profile. For beers that don’t require a phenolic heavy brand profile the presence of this flavour indicates wild yeasts that have contaminated the brewing process.
This flavour can also occur in all beverages due to hygiene related issues – bacteria can impart this flavour into raw materials, dispensing and processing equipment.
