UPDATE:
Decided to rack the mead today as it is the only free time I had for a few weeks and it just felt like the right day. Right in the middle of the times on all of the various recipes I've looked at.
The gravity reading was about 1.035 I think. I'm definitely getting a more expensive hydrometer for my next batch of anything I do... I was also beginning to mistrust the fermenter, so ya; I got up in the morning and get it set into my head that I must rack this stuff tonight, so that's what I did.
Anyway, a few things have changed since my last update. The smell has changed to a sort of sweetish sourish smell with a lot of yeast.
Racking went well, got out a full 23 litres without picking up any of the beige gunky stuff at the bottom of the barrel.
I also tasted it, which was the most interesting part for me.
It tasted slightly yeasty, but also bitter and pretty sharp. A definite alcohol taste too, definitely more ABV than I was expecting given my pessimism, maybe around 10%, but not exactly a hot taste. I'm guessing in the ABV based on the alcohol taste being about twice as strong as a 8% cider I had today and taking into account un-aged alcohol. Though you guys might tell me that it's more likely just really hot at about 3% ABV, which wouldn't surprise me by my luck xD
Anyway the thing that surprised me is that it had an under taste which was mead. It tasted like mead like I buy in a bottle, only with a layer of sharpness. Surprised me because I had more or less been expecting it to taste like sour milk and vodka xD
Anyway, odd smell, odd taste, though I'm sort of encouraged by it. But I'll leave it up to you people of experience to tell me to be happy to put it away for a few months or just put it back into the big barrel and make it into vinegar xD
