I don't heat my honey. I believe that doing so causes a great loss of aromatic elements that I want to keep in my meads. However, there is very little data on which to base a conclusion. The only report of a side by side comparison of a boiled and non-boiled batch that I have seen so far was done by Erroll Ozgencil in his
Washington Winemaker blog. In it he used a very strong honey (heather) and the boiled batch was preferred.
I have outlined my criticism of his approach in a thread over on
GotMead, and several of us are currently running side by side batches to try to establish more data points with different types of honey. Mine is almost ready for bottling using another strong dark honey (mint), and I want to set up another comparison using a light honey like orange blossom. In a couple of years, we may be able to speak with much more certainty about the pros and cons of each approach.
I would invite anyone here interested in collecting some data, to try setting up two identical batches (a boiled and non-boiled) and fermenting them out. If you keep a good brewlog that information will be helpful to future generations of mead makers. If you will post a link over on GotMead to any of your data, we'll try to tabulate it over time, and eventually we'll have enough comparisons in one place to be able to draw some conclusions (at least that is my hope).
In the meantime, I keep advocating no boiling based purely on faith and anecdote.
