It's pretty decent stuff, but when they say sweet, they mean it.
All the batches of mead that I have made, were based on 15 lbs honey and 5 gallons of water. I believe this recipe more so than the yeast contributed to the overall sweetness of the resulting mead.
That said, make a starter and watch your fermenting temps and you'll be fine. The longer you let this stuff age, the better.
