The distilled water thread got me thinking about a Belgian dark strong ale I have sitting in the secondary right now. I did a hydro check tonight and I've hit my attenuation (from 1.086 to 1.024), but I worry a bit about the high FG when I bottle. (This is the third consistent hydrometer reading, so I think I'm not moving much from here. 3 weeks in primary, 1 week in secondary so far.)
Is there any damage in diluting a bit with bottled water here? I overshot OG by a pretty significant amount because I didn't top off to five gallons when I brewed. My thinking is that a half gallon of more water will get me down about 4 gravity points and put me at 1.02, which makes me more comfortable that I won't get bottle bombs. I also think this will put in the intended FG range.
