i'm still having trouble getting consistant hydrometer readings for my OG. FG is typically fine and consistant, but i get something like a .005-.015 swing on my OG. I *know* that the problem is that i'm not getting the wort mixed with the tapwater (i do partial boil extract batches, at the moment.) can someone look at the following equation, and tell me if this should work (not to replace getting it sufficiently mixed, just as a reference to make sure that it is)
(SG of Wort)*(# of gallons after boil) + (# gallons tapwater)
-------------------------------------------------------------
(gallons in batch)
for example, if i have 2 gallons of 1.15 wort, and fill with 3 gallons of water, it'd look like this:
(1.15(2)+3)/5= 1.060
does that sound right? i'm NOT very good at math, and things that make sense in my head are often wrong, so i wanted to double check.
of course, i'd be extra careful to make sure that everything coming in contact with the wort is sanitized.
