Four weeks ago, I racked the mead into a carboy, to allow secondary fermentation to proceed, which it did. Fermentation was more or less over a couple of weeks ago Tonight, I decided it was time to rack the mead into a clean carboy so the mead can bulk-age, lose CO2, and clear up.
During secondary fermentation, there was a small froth on the surface, which isn't a big deal. However, as fermentation slowed down, a fine, beige solid remained on the surface of the mead, and along the inside, top surface of the glass, under the neck. The solid never dissolved.
After racking, I managed to swipe my finger into the dirty, empty carbon, and get some of this material. It was granular, hard, but seemed a bit 'gummy', like paraffin wax. Question for honey and mead people: Is this beeswax?
This particular honey is not heavily processed. I used 2-3 kg of honey, so it wouldn't be a surprise if there was a small amount of beeswax in there.
Sadly, before I could measure specific gravity, I dropped my hydrometer on the floor. So, I cannot estimate alcohol content of the mead right now.
The mead sure tasted good, though. I was surprised by the sweetness. Fermentation was OVER. There shouldn't be any residual sugar in there. It could be that there are other sugars (e.g. pentoses or something like that) that the yeast did not touch. This deserves some research. Question for honey people: what types of sugar are present in honey?
