I make a ginger in alcohol product and am having a problem that I though you could help with. I juice fresh ginger root through a standard juicer, discarding the solids, then let it settle in the fridge for 24 hours to let the remaining fibrous component settle out. After mixing with alcohol, either there is additional precipitate in the solution (not really solid and can't be strained; it's more of a floating conglomerate) or the ginger layers out.
Do you have any tricks to make the ginger more soluble in alcohol? Is this a pH thing or is the alcohol precipitating additional solids on its own irrespective of pH?
