RE: Mead gravity question

I have never checked the gravity on any mead I've ever made. I simply use that 3 lbs of honey per gallon ratio. Since we're on meads today, I had a very strange mead reaction which turned out rather well. I started a mead in Nov of 2001 using some assorted dryed fruits. These fruits basically melted when I heated my honey and water for good mixing. Ever since, it has not wanted to clear out even after two rackings. The other day, I topped off my jugs with a honey water mixture that was still pretty warm from mixing. (80-90degrees???) Within two days, both jugs dropped absolutely clear. Anyone know what, why, and how this worked out so well? They weren't really active so I don't think it's simply killing off the yeast but hey, I'm not complaining Mike Moranz, President Minnesota Home Brewers Association
