We decided to do a taste test. The lighter honey on the left almost certainly came from citrus; it had a very light almost lemony sharpness to it. The darker honey on the right was more flavorful and more of a carmel flavor to it.
It would have been great to keep them separate but I had already put them in the bucket and figured it would be cool to find out what the 50/50 blend would taste like. It's kind of like blended Scotch vs. single malt.
I think that over time I might be able to look for signs when one flow is ending and another beginning to keep the honey strains more discrete.
