蜂蜜の原料 material of the honey

この蜂蜜瓶のラベルには屋久島と書かれていますが、夏の間ミツバチを北海道へ連れて行き、アカシアの蜜を集めたそうです。アカシアの蜜だとどうしてわかるのでしょうか。何を集めるかはミツバチ次第だと思います。機会があれば養蜂家に聞いてみましょう。

The label of this honey bottle was written as Yakushima. But they took bees to Hokkaido during summer and collect the honey of the acacia. Why does they understand that it is the honey of the acacia? I think that it is up to bees what the insects collect. If there is an opportunity, I ask an apiarist.
