  Lots of people don't seem to know the difference between accuracy and precision. Or that you
  can be as accurate AND precise as you want to be with any system of measurements.

  I don't see how it's easier (or more accurate) one way or the other. Just different constants
  in the equations.

  Ethanol works fine. So does isopropanol (rubbing alcohol).

• Posted in thread: efficiency calculation - how to account for lactose on 07-17-2012 at 04:51 AM
  Lactose has the same molecular weight as sucrose, so I'd just use the same potential value as
  sucrose (1.046 per pound per gallon).

• Posted in thread: effects of mash temps as a function of time on 07-15-2012 at 05:59 PM
  A mash-out to "preserve the sugar profile" would need to be high enough temperature to
  deactivate (denature) the amylase enzymes. The traditional temperature for this is 168 F.If you
  mashed for an hou...

  The bottom line for me is that rehydrating is bone-simple to do, and gets active fermentation
  going much faster than direct pitching. It also gives you a good indication of whether the
  yeast is any go...

  First, don't dissolve it in "hot" water. Dissolve it in warm water -- 90 deg. F is ideal. Much
  higher than 100 deg. F will kill the yeast.Dissolving directly in wort subjects the yeast to
  osmotic shoc...

  Could have been the specialty malt, depending on the type and proportion of the grain
  bill.Could have been the mash temp. overshoot, which could have knocked beta amylase out of the
  picture.Or the yea...

  Understood, agreed. However, there's got to be a diference between 1. (a 6 row grown in Iowa
  and malted in chicago by maltster x) and 2. ( a 6 row grown in germany and malted by maltster
  y) The brewin...

• Posted in thread: Fermenting S-04 Cleanly on 07-10-2012 at 10:29 PM
  I've convinced myself this is a good idea for beer clarity, since I know from experience that
  S-04 flocs out extremely well. I'm concerned about flavor contributions. I've never used S-04
  in such a li...
