Ingredients / Re: New bulk grain supplier
« on: November 30, 2010, 12:35:48 PM »
Free shipping, though, as I understand.  I'll be curious to see how things work out once they open.
If you click the "shipping" link it says shipping charges are based on weight

All Grain Brewing / Re: batch sparge water, how much will fit
« on: November 30, 2010, 06:50:22 AM »
I think I figured out what they are trying to tell me.
10 lbs grain 10 gallon batch 1 quart per lb= 2.5 mash 8.8 sparge
This is the mistake they're making, in my opinion.  I recommend upping the qts/# with smaller grain bills.  Generally, I add enough water to the mash to get half my volume from first runnings after absorption.

For example, for 10# in a 10 gallon batch, assuming 1.2 gallons absorbed and 1 gallon boiled off:
6.7 gallons mash water, for 2.68 qt/#.
5.5. gallons sparge water.

If the 2.68 qt/# makes you nervous, then mash in with 5 gallons, for 2 qt/# and add the remaining 1.7 gallons as a mashout or to the sparge.
I agree.
I just threw those numbers out there to illustrate the point they were trying to make. I agree with adjusting the mash water grain ratio. I would rather up the mash water and do one batch sparge, then hold hard and fast to quarts per pound rule and do double sparge.
Nobody actually said to use those numbers.

Yeast and Fermentation / Re: Old Newark Ale Yeast

I mashed at 154, 153, 154. However let me say that the accuracy of my thermometers may be suspect.

I've done three beers with it repitching twice.
First was a 1.045 og beer with 78% attenuation
second was a brown ale 1.060 og 80% attenuation
third was a pale ale 1.043 og it's at 80% attenuation after one week
I fermented them all between 64 f and 68 f.
The pale ale is still in the fermentor but the other two turned out real well.
I think it would be great for a dry stout.

I think I figured out what they are trying to tell me.
10 lbs grain 10 gallon batch 1 quart per lb= 2.5 mash 8.8 sparge
20 lbs of grain 10 gallon batch 1 quart per lb=5 gallons mash 7.6 sparge
30 lbs grain 10 gallon batch 1 quart per lb=7.5 gallons mash 6.4 sparge
40lbs grain 10 gallon batch 1 quart per lb=10 gallons mash 5.2 sparge
so as the grain weight goes up the mash volume  increases and the sparge volume decreases
Looking at it like this makes sense but still doesn't seem right.
I really need to find a job so I will stop obsessing over this stuff. :)

I too have a 5 gal mash tun and for anything below 14 Plato I tend to be able to get away with a single batch sparge. You only gain about 3% lauter efficiency.

Do you think you could post some of the mash water, sparge water volumes and grain weights that you know work in the 5 gallon mash tun?
I am trying to see if I have this figured right.
Over on the HBT forum some folks are trying to explain to me how with smaller grain bills they need to double batch sparge and with larger ones they can do a single? This to me is totally counter intuitive. Larger grain bill means more water and more grain taking up room in the mash tun. So how does a larger grain bill lend itself to a single batch sparge?
I never saw a post with " My grain bill is to small to do a batch sparge?"
 ??? ???

Sometimes I use some dishwasher powder to give the oxyclean a little extra kick.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
 Preemptivly  though I will prop one edge of the bottom of  my fermenter on a 2X4 (raise it 2" not 4") and that way
when I go to siphon to the keg I level the fermenter and place the bottom of the siphon in the shallow
side of the yeast cake. You'll notice that there is an obvious angle to the level of the cake. Then follow what
Tom said for the keg part.
I never thought of tilting the fermentor before racking to push the yeast cake to one side.
That's the kind of simple thing that one learns on the forum that is actually a really great idea.

Yeast and Fermentation / Re: New Yeast Book
« on: November 26, 2010, 05:07:13 AM »
The book is good has a lot of information.
It's very comprehensive if you have a question about yeast the answer is in there.
If you are interested in setting up a yeast culturing lab I would definitely recommend it.
The most practical piece of information I found was how to a test for diactyl.
If you already know about starters, reusing yeast, fermentation temp control, pitching rates, and are not interested in all the real geeky stuff I don't know how much usable info you'll get out of it.
I am not saying don't buy it, I am glad I read it, but it hasn't really changed anything I the way I ferment the beer.

Mash tun is 5 gallons.
I know I can do the double batch sparge, but I have been getting good efficiancy
with the single, around 80%. Also I like playing around with the #'s and I have have too much free
time.

and
preboil volume+(lbs x 0.13)= total mash and sparge water?

so
mashwater+(.09 x lbs of grain )= mash volume ?

got it thanks
I thought the 0.9 was absorption ratio not the 0.13

The ROT is 0.09 gal per lb of grain. That will vary somewhat depending on kernel size, crush, etc. But it should be a decent starting point. Once you've drained your first runnings, it will over-estimate because of the soluble extract you've removed, but that just gives you a safety margin. For your example, an 8.5 lb grist, after being drained, would have a volume of 8.5*(0.09 + 0.13) = 1.87 gal, so once you add the 3.75 gal of sparge water the total volume will be ~5.62 gal.

What does the 0.13 represent?

That's what I use to see if my mash will fit.
What I want to know is will my sparge water fit?
I have 8.5 lbs of grain
I mash with 3 gallons of water 1.4 quarts per gallon
this takes up 3.74 gallons in the mash tun.
I then mash out with 1 gallon boiling water.(I know this isn't really necessary)
And then drain.
I then collect 2.75 gallons of wort.
For 6.5 gallons pre boil I need to add 3.75 gallons of sparge water.
I want to figure out if the 3.75 gallons plus the grain will fit in the mash tun?
