Smicko, I'm assuming you are using a hydrometer, what ingredients exactly are you putting in to get 10% booze content.. I tried doing the same thing using various fruit juices/dextrose/honey/champ yeast etc A couple of years ago.. It worked ok. Doubt alc content ever got that high. Pro tip Don't keep reusing yeast leftover it loses potency over time, yeast is cheap, ingredients aren't.
Stu it depends on the yeast strain you're using as to how high your ABV will get. I'm using ec1118 which is a champagne yeast that will attain about 18% given sufficient fermentables, before it shuts down. You can also get a strain specific for brewing spirits that will ferment up to the low 20's before shutting down, it does tend to give 'off' flavours which makes it unappealing for brewing but obviously not an issue for distilling as those characters disperse with the distillation process. The reason I like to reuse the yeast beast is that like most vigorous yeast strains ec1118 has a tendency to strip fruit character from your brew, but once you've done a brew with added spice, honey, sultanas etc the yeast cake retains some of these flavours and brings them into your brew with an ABV of around 5-6% which is about where I'd like it.
