A study by researchers at the University of California Berkeley has found that ethanol is surprisingly common in floral nectar, the sugary fuel that keeps pollinators alive. Yeast feeding on those sugars produces trace amounts of alcohol, and in this study, it showed up in 26 of the 29 plant species sampled.
Individuals allergic to bee stings can safely consume honey because the venom produced by bees is not related to honey. The venom is injected through the stinger, while honey is produced from nectar.
