Do I need to wait until I get a "hard pack" of yeast? How long might that take?A couple of days
in the fridge is normally sufficient. The rate at which the yeast settle decreases with time,
so as time...

As nutrients in the wort are depleted the growth rate slows and the yeast will build up their
glycogen reserves. When pitched into a fresh wort there will be another lag and growth phase as
a colony. ...

malt syrup (liquid malt extract?) It's actually high maltose corn syrup. There is almost no FAN
in it. Very different than malt extract.

That's an interesting read, but I'm not sure that it would represent results from an all barley
high gravity wort most homebrewers would prepare. Do you think this could be Nitrogen
limitation?A 12°P ...

You're doing more right than you give yourself credit for.1) A refractometer is not the most
accurate way to read OG, due to the alcohol?! Use a hydrometer (I'll get one right away)! As
long as you co...

When you used the refractometer for the final gravity did you adjust for the alcohol in the
beer? (If you didn't do the correction, then the actual final gravity is 1.017. See here:

Most likely that's just about where it will stop, and that's fine. Knowing the OG, recipe and
mash schedule would help to firm that up. If you want to do an experiments to find out if that
really is t...

Could I use the filtered water coming out of my fridge? Water filters can harbor bacteria. I
wouldn't trust it. Do I still need to boil it or could I nuke the wort for 1-2 minutes in the

If you use bottled water and DME directly from the manufacturers bag there is no need to boil.
The manufacturing processes are quite sanitary.
Posted in thread: harvesting bottle dregs. Is this yeast or other trub? on 05-09-2015 at 04:33 PM
I appreciate your honesty and think i understand where you are coming from.In some bottle dregs
I've seen as much as one bacteria cell for every 10 yeast cells. Plating to grow a colony from
a single ...
