I'm currently reading Ken Schramm's book and soaking it all in but I do have a basic question that seems a bit tough to answer. I prefer my alcoholic beverages to be of a drier nature. Many, if not most, of the mead recipes that Ive seen are for sweet meads. What exactly (other than yeast strains) contributes to the dryness of the mead? My guess is the ratio of honey to water. Schramm seems to like the 2 parts honey to 1 part water ratio for most of his meads and a podcast with Michael Fairbrother says 75% honey/25% water. Is there a magical formula that decides the outcome much like mash temp is a critical element in beer?
If you want a dry batch, as at least one person has already pointed out, use less honey.
The issue with honey, is that people expect it to be sweet, so if you serve a dry mead to someone who knows little or nothing of meads, they may or may not enjoy it. After all, once the sugar content has been fermented out, what's actually left ? Not a lot, apart from a small amount of residual non-sugar flavours, water and alcohol.
I also think you've mis-read what Ken says. He uses various recipes for his examples, yet if you mixed up a test measurement batch of honey and water i.e. presuming a 100ml test jar, used 66ml of honey and 33ml of water, you'd end up with a gravity that is unlikely to even start fermenting. The yeast would probably just "turn it's toes up" from osmotic shock, in other words, far too high a starting gravity.
You will find recipes that do contain a lot of honey (look up some of the Polish mead recipes - how the hell they ferment them, I don't know, but would have thought that they start with a reduced gravity must and then step feed), but from a lot of the info, you'll find that the common ratio that's often used is 3lb honey made up to a gallon i.e. given that a gallon of honey weighs about 12lb, that's would give you about 1/4 or 25% honey to water ratio.
If you think that Ken meant something else, then send him a PM. He posts here sometimes (though I believe he's currently recovering from surgery). You never know, he might answer your question.......
