Most samples of honey contain detectable levels of yeast, with counts ranging from one to tens of thousands of spores per gram. This fact often surprises consumers, as raw honey is typically known for its long-term stability and resistance to spoilage. But how can honey remain preserved for years with yeast present? The answer lies in the honey's unique composition and the specific type of microorganisms involved.

Despite its sweetness, the high sugar and low moisture content of pure honey make it an inhospitable environment for most yeast. So, does yeast feed off of honey? The answer is a nuanced 'yes,' but it depends entirely on the context and whether water or other nutrients are added to dilute it.

While honey is famously known for its longevity and resistance to spoilage, all raw honey naturally contains wild yeast spores. This might be surprising, as most people associate yeast with active fermentation in baking or brewing, yet in honey's unique composition, these microorganisms typically remain in a dormant state. It is only when certain conditions are met that the yeast can activate and begin a fermentation process.
