That may be true, but virtually none of the commercial brewers I know have a degree.

All Grain Brewing / Re: Batch Sparge Water
« on: April 27, 2010, 09:58:49 AM »
Euge, if you have a chance, would it be possible to give me an example of how you would go about calculating the total volume of cool water to start with?  How much water would you mash with and then how much you would batch sparge with to get your preboil volume?  Assuming you mashed 9 lbs of grain and wanted to end up with a batch size of 3.5 gallons.

If you have the time, I would appreciate it...this is the one variable of my brewing that is giving me the most trouble right now.

Thanks!

bbump22, from my website at www.dennybreww.com....

The main concept we’re going to be working with is that for the best efficiency, the runoff volumes from your mash and batch sparge should be equal.  In order to do that, it’s sometimes necessary to infuse your mash with extra water before thefirst runoff.  Here’s how it works...

R1=initial runoff volume which = mash water volume - water absorbed by grain
(assumed to be .1 gal./lb. for this example since that’s the way my system works...use your own figure)

S= batch sparge water volume
V= total boil volume (amount in needed in kettle for boil)
I=volume of infusions for a step mash

R1+I+S(1)+S(2)+S(etc.) must equal V
AND
R1+I=.5V

Let’s see how this works in a brewing session.  Assume a recipe with 10 lb. of grain, and that you need to collect 7 gal. of pre boil wort.  A mash ration of 1.25 qt./lb. would require 12.5 qt. or 3.125 gal. of strike water.  Based on an absorption of .1 gal./lb., the mash would absorb 1 gal. of water so we’d get 2.125 gal. of water from the mash.  Since we want to collect 3.5 gal. (or 50% of the boil volume), after the mash is complete we’d add 1.375 gal. (5.5 qt.) of water to mash tun before the first runoff.  Stir the additional water in, let it sit for a few minutes, then vorlauf until clear and start your runoff.   After the runoff, we add 3.5 gal. of batch sparge water.  Stir it in well, then vorlauf and runoff as before.  These two runoffs will give us our pre boil volume of 7 gal. of sweet wort.

FWIW, I've never noticed consistent enough variations to say that one brand flocs better than the other.

Did you end up with the 5.25 gal. your recipe calls for?  If you were short on volume, the OG could be higher.

According to my taste buds, I agree with Kris.

And Denny - I could tell ya, but then I'd have to kill you and that would be kinda kin to stepping on the last member of squishy endangered species.

Man, that just made my day!  Don't worry, I'll get it out of you when you're drunk at NHC!

All Grain Brewing / Re: Batch Sparge Water

Cool, thanks!  I need to get my sparge calculation down better and get an accurate volume measurement.  I am tempted to buy a kettle with a sight glass just to be more certain of my volume.

There's an even easier way to do it.  After you run of the mash, measure how much wort you have in your kettle.  Subtract that from your boil volume.  The answer you get is how much sparge water to use.  Since the grain is already saturated, it won't absorb any more water.  The only variable will be any dead space in your mash tun.

So, what's the big project?

Boy, there's usually something for Big Brew.  I don't recall specifically hearing anything, though.  I'll see what I can find out.

You can make 1-2 gallon batches on the stove in a stock pot using a spaghetti strainer.  I knew of a 70+ year old woman who would do just that.

And you can take a sample of that wort, put it in a jar, and know when your fermentation in your closed bucket is done, just by watching what is going on in the jar,

No need to thank me, I am just here to help.

Was that Coly on B&V?

And thanks (HAHAHAHA!) for the fermentation tip!

Not as far as I'm aware.  My friend Bob, who authored the B&V post that turned me on to this, made some himself and is doing a split batch to test them.  I intend to try it myself as soon as I have time.  Bob got the idea form an article Charlie P. wrote in Zymurgy.

I'm familiar with it.  Does it have any application in brewing?

I would like to see some agreement with the shipping companies ( Fedex, UPS ) the relax the restrictions on shipping beer for competitions.  Also, maybe a deal could be struck with them for contracted shipping rates at a discount.

AFAIK, we have talked to private shippers and they didn't show much interest becasue the volume was so small they wouldn't make much money on it.  While I don't think that avenue has been ruled out, I believe that at this point the focus is on legislative changes.
