Every year when I harvest honey, I keep samples. I try to keep samples in the same type of container, because the honey will have a different appearance in thinner versus wider containers. For three years (I'm not certain which years) I used pint-size jelly jars. The same bees produced these honeys, in the same location, and look at the difference. One year, the farmer to the east o the farm put his fields in timothy, and the bees took a light and sweet nectar from it several times that summer. The farmer was trying to cut before it flowered, to make hay, but the plants got ahead of him a bit and the bees benefited.
