> In response to the amount of caffeine in used coffee grounds. 41 mg of caffeine per 17 gm of used coffee grounds. I have observed my bees rolling in coffee grounds for years. As with prior years; once our pollen flow started on February 28th. they stopped.
Hey, thanks for the link. Interesting that about 1/3 of the caffeine in the coffee is left behind. So -- do you think they are getting anything from the coffee, or just trying to?
