comment Lots of trub affecting specific gravity readings?
Suspended particles do (what I wrote) and non-suspended particles don't (what Denny wrote). The key is the use of the word trub that normally refers to unsuspended particles. Adding matter to a volume of a liquid increases its density and therefore its specific gravity. So the issue as I thought you were asking is not if the trub effected your FG (what Denny is referring to) but would what becomes trub effect your SG. If this is what you were indeed asking, the answer is yes it can.

Thanks for the link, Atom. Since I teach chemistry, I'm always looking for cheaper sources of equipment.

Or another potential method (based on what I know as a chemist and a decent chef) would be to melt the chocolate and slowly add everclear or good vodka until "soupy" at room temp, then add this to your mead. Two advantages: choco won't settle out and you up the ABV in the process :-). But I haven't tried this one yet in mead :-) (have used it to make a bittersweet spiked choco eggnog).

chocolate is soluble in alcohol to some extent (you've probably seen chocowine before). The choco mead that I had was warmed and blended while warm with melted choco (start the mead in the blender at high speed, then very slowly add the liquid chocolate as a thin stream to insure mixing, until the mixture is at the desired balance of sweetness and choco flavor, doesn't take much using high cacao choco). The other method uses choco nibs (These are bitter with intense choco flavor) in a secondary and letting the mead age over the nibs for several weeks (was on a tour of a meadery in CO).

comment How do you blend your meads/wines?
Not really (threshold). I'm a chemistry prof and what I wrote above is the science. Brewchez is correct in the comment about layering. Layering shots is a prime example of the effect of spec grav, but in what you are asking doesn't apply. Elevated temps increase the ability of the molecules to mix and stay in solution.

Temperature control is the key. Keeping the temp between 70 and 100 F for a short time will avoid any negative effects. These temps are well below the boiling point of the flavenoids that give the mead/wine flavor.

good suggestion about the pH. Sometimes this factor is forgotten when trying to figure out why fermentation stops early. Flynn Scientific makes a cheap (most cost over $100) and accurate handheld pH meter that I use. See ( flinnsci.com/store/scripts/prodView.asp?idproduct=17142 ). Or an aquarium meter can work but is less reliable for brewing IMHO (see ebay.com/itm/… )

the FG you state should allow champagne yeast to continue (I usually start at this spec grav and I use cote des blancs or premier cuvee and end at 1.009)

comment Effects on homebrew from Fluoride in tap water
that's the primary concern about fluoridation, that there is little control of the concentrations. To inhibit lipase, the concentrations are low enough to what would be found in treated water (that was the point of the research).

comment Is a late addition of sugar into wine a month after primary ended detrimental?
adding the campden will inhibit the suspended yeast and no further fermentation will occur. This is a technique often used to stop ABV at a specific level, when carbonation is not desired. IF Max does this, he will effectively sweeten the wine and there will be no additional (significant) alcohol produced. Good suggestion if he is satisfied with the alcohol level and is just wanting to sweeten it.

If you carefully siphon, you should reduce the addition of oxygen, and avoid stirring up the trub when you add it back.. Guess it is a balance thing and on thinking about it, I'd probably just add the sugar (dissolved in some of the wine) to the carboy/keg and allow the sugar to dissipate into the wine, if I didn't think that I could avoid adding oxygen in during siphoning. Just a matter of technique.
