I haven't used it for mead, i would never do that. I have used it for my first couple of stouts. It does ferment a 1.080 gravity beer to 1.020 in only four days. But just because its fast does not mean that it is good. It produced a lot of phenols in the stouts, even when fermenting at 65 fahrenheit. Don't use it just because it is lying around. I know you want to get your mead going but take a fraction of your time and get some actual wine yeast. If you want it sweet you're either going to have to add some sugar back into the mead after you've killed off the yeast or make a high gravity mead. Use some yeast that is low attenuation because nottingham is for one not for mead, and attenuates high. Use some Lalvin D-47 or RC 212 if you really want it sweet. You should be happy having a O.G. of 1.100 to 1.120. Apple Wine is only 7-9% and has a low final gravity. Honey will by itself have a higher final gravity. Not every bit of it will ferment.
