I was going to heat the water to 185 then add the honey I went going to boil it , should I boil and what is the difference between the two.
STOP right there... Do NOT heat the honey above 110F, 100F being even better as a ceiling. IF you do, you'll start to boil off all the more delicate flavors that are present and, more likely than not, you'll not enjoy the mead when it's done. IMO, boiling the must, for mead, should be illegal...
Also, use a honey that's strong in flavor. You do this so that more will come through in the final product. If you use a honey that's mild, or barely moderate in flavor, you'll have a weak flavored mead as a result.
The 1/3 break is the point where 1/3 of the sugars present have been consumed by the yeast.
SNA= Single Nutrient Addition...
You DO have yeast nutrient on hand, right?? If not, get some DAP (Fermax works too) as well as some yeast energizer.
I would advise going over to the Got Mead forums and look over the newbee section BEFORE you start the batch.
Something else to keep in mind... Making mead is NOT like brewing beer. Even the terms are different (which should give you an idea of how different they are). With mead, you give it care, and feeding, until the 1/3 break and then you leave it the hell alone until it's done fermenting. However long that takes. I have a batch that was fermenting for 3-4 months before it finally stopped. You will want to degas and aerate the must until you hit the 1/3 break. Once fermentation is complete, and the mead has cleared at least some, rack to another vessel. Do not rack if it's not been at least a month since pitching the yeast. You can also go longer before racking (there's one yeast that is an exception to this, but doesn't sound like you'll be using it) without issue. Then let it settle and start to clear again. Check on it 1-3 months later. If you see a decent amount of sediment/lees in the bottom, rack again. Continue until it's extremely clear.
For an 11% ABV mead, I would give it at least 9 months before considering bottling. A full year would be better. If you go less than a year, you might want to stabilize the batch before bottling (to prevent bottle bombs).
I have two 14% meads in vessel right now that I started in [early] December 2011. I've racked them a few times so far, and will probably do so sometime either this month or first half of next. I plan to bottle after a year has passed since they were started. I might even let them go until sometime early next year before they get bottled. This level of patience [IMO] is CRITICAL for getting great mead. IF you try to rush a batch through, don't be surprised if you're not pleased with it.
Something else to consider. Mead, like most good/great wines, gets better with age. My original batches (from fall 2010) are getting better as time passes. I have enough left to be able to sample as I wish. I also bottled part in 375ml [frosted glass] bottles. I used quality corks in the bottles, so that I wouldn't need to worry at all. Pretty much everyone that's tried my mead has great comments about it. If you want a similar experience, then you'll need to give the mead the amount of time it needs to get there.
