What is sour honey?

Sour honey, also known as fermented honey, occurs when honey is exposed to moisture or certain yeasts, leading to fermentation. This process can produce a tangy or sour flavor due to the production of organic acids and alcohol. While some people enjoy its unique taste, it can indicate spoilage in commercial honey, making it less desirable for certain uses. It's often sought after in traditional practices and can be a sign of natural fermentation in raw honey.
