Yes Dave honey pulled at different times will have different flavors. The reason is because they are visiting different flowers.
We have pulled two weeks apart in late spring from the same hive when nectar flow was really good and got two different flavors. Just a frame or two not the whole harvest
Also, we have pulled both light and dark honey from the same hive. They have totally different flavors. The mint tasting one was a light honey in a hive with a dark honey which tastes smooth and buttery.
Processing the colors separate gives you what is called artisan honey which commands a higher price than a honey produced from combing all of it together.
