Can i get the numbers run on this

[Stile]

6# White Wheat
3# Vienna
1# Honey malt
1# Carapils

I know i need 3.5 gals of water for the mash, but how much sparge water do i need?

What is your batch size? We can't determine the pre-boil volume without the post-boil target...

 

[The Pol]

If you boil off 1.4 gallons/hour for 60 minutes... you will need to mash in with 3.5 gallons and sparge with 4.4 gallons... this will give you exactly 5.0 post boil

Better yet, 1.5 gallons gets absorbed in the mash... so you can figure it from there too.

3.5 gallons in, minus 1.5 lost in absorption, leaves 2.0 gallons, minus your boil off, say 1.4 gallons, leaves you with .6 gallons, so you need to sparge with 4.4

 

[Stile]

Whoops sorry, ya 5 gallons.

So i'll get 2.1 gals from sparging for sure. How much wort will the tun give up from the 3.5 inital mash? And based on that amount i then add water to make up the 6.4 gals total..... right????

 

[The Pol]

Nooo, sparge with 4.4 gallons, boil off about 1.4 gallons and end up with 5 gallons

If you mash in with 3.5 gallons, the mash will absorb 1.5 gallons, leaving 2.0 gallons.

 

[Stile]

Wow, i'm visually dyslexic today. 4.4 gals.

Thanks

 

[The Pol]

You will sparge with 4.4, and collect 6.4.... boil down to 5.0

Thanks Pol,

Training wheels are coming off this weekend and i'm already stressing

 

[The Pol]

No problem!

 

[Anthony_Lopez]

make sure you are using that 4.4 gallons for a sparge!!!!!!!!

 

[Stile]

One more quick question??

I'm using Green Bay Rackers..... How do you figure out the mash thickness?

 

[The Pol]

WOAH... okay

What is your target mash temp? Green Bay Rackers has a reputation for being off a few degrees...

 

[The Pol]

Right now your mash thickness is about 1.26qt/lb... which is good.

 

[Stile]

I figure 155.

 

[The Pol]

Okay, to rest at 155F, mash in with 3.5 gallons at 164.8F....

Any good brew software avail??

 

[The Pol]

I use StrangeBrew.. I like it a lot. ProMash is good, others as well.

 

[Stile]

Once again, thank you good sir.

 

[The Pol]

No problem, you will be fine.

I use BeerAlchemy on my iBook, but these are handy online calculators:

my rule of thumb is to have the same volume of sparge water as your pre-boil volume.

Aka - If I'm going for a 6.5 pre-boil I'll have about 6.5 sparge water ready - sometime's I've needed it all, sometimes I haven't.
