>He liked Phils Philler the best because (1) the beer doesn't spray out the
bottom (so no aeration at that end) and because (2) it left very
little head room (so little oxidation potential at that end).

Phil was in Milwaukee and when he demonstrated the filler to me, it seemed to
squirt beer around the top somewhere. I left with the general impression
that it is a bit messy.

>I'm currently using one with the valve at the bottom.... But it does
"spray" beer out the bottom.

There are two simple tricks to minimize the spray. First of all, you raise
the bottle to reduce the head pressure when starting and secondly if you tilt
the bottle, you quickly cover the end of the wand with beer. Once it is
covered, put the bottle back down to the normal filing location.

>I posted here about 2 months ago complaining about low yield. The
general concensus was to slow down my sparge, and that helped, but I am
still not up to where I think I should be. Here are the details:

8 lb klages
.5 lb munich
.5 lb crystal

>I use a one step infusion mash at 155 for 45 minutes.

> The starting gravity is 1.036 and finishing is 1.006. With 9 lb
of grain I think I should be getting around 1.040.

> I just brewed a similar receipe using 12 lb of grain and I only got 1.042.

I have no experience with plastic bucket brewing, but the second figure is
more of a problem than the first which is in the ball park. You may be
getting all you can get by dumping hot water onto a bucket full of malt.

I use an active mash, i.e. in a kettle on the stove. This allows a mashout
at 178F and I sparge with boiling water. My typical yields for six gallons
are 1.040 with 9 lbs and 1.055 with 12 lbs.

I have tried stirring the mash after extracting 5 gallons and get real
excited to see the gravity of the next sample take a quantum leap but the net
extraction does not seem to be effected.

The initial sample out always seems to be around 1.080 no matter how much
grain I use.

I would be interested in comparing notes with others on yield just to see
what the mean values really are.

>My grind seems good, I get my grain from The Cellar in Setttle, (They are
only about a mile from my house). They have a good roller mill there that I
use, and they checked the grind and thought it looked fine.

There are those who claim that fresh is where it's at. For example, one
brewpub claimed they had to increase the amount of malt by 10% if it sat over
night after milling. I rather doubt this but people have also claimed their
yields went up by 10% when they used a MALTMILL. So who am I to argue.
