Thank you so much for your responses. I think we will try the oven trick. After asking more questions we have learned that people have had very good honey from this beekeeper in the past. He said the bees appeared to have added honey after he tested the moisture content on a few frames but thought it wasn't enough to raise the moisture as much as it did. I guess I will chalk this up to a good learning experience for us as new beekeepers. We weren't even aware this could be a problem, we thought capped honey was good to go. We have much to learn, but happy to do it. Thanks again.
