Dumb all grain question

[espringm]

Okay so here is my first all-grain that im planning. Its a northern brewer kit Bavarian Hefeweizen 5 gallon batch.
Recipe:

-- 5.5 lbs. Weyermann Pale Wheat malt
-- 4 lbs German Pilsner malt
1 oz Tettnang (60 min)
WYEAST #3068 WEIHENSTEPHAN WEIZEN

Okay so according to the kit, and beersmith said the same, mash at 153 (167 infusion) with 10.93 quarts and mashout 170 (210 infusion) 5.45 quarts. I have a 70 qt cooler w/manifold for mash tun.

Okay here is where i'm confused, the liquid going into the mash tun is 16.93 quarts or 4.09 gallons. Shouldn't i need more liquid to be over 5 gallons before I do the boil, accounting for evaporation. What am i missing?

You are missing the sparge water. Before you attempt this I recommend you read up on the process first. John Palmer's "How to Brew" is a good place to start.

Where is your sparge at? Your sparge is what brings the volume up to between 6 and 7 gallons.

Yeah like others have said you are missing your sparge water. If I remember correctly this recipe calls for mashing at 152. I just did this kit about a week and a half ago. Can't wait for it to be done. Smells amazing.

Stupid question... what is the difference between sparge and mashout?

 

[Breck09]

Mashout is just adding water to the tun at the end of the 60 minutes to denature the enzymes. You then drain all of that liquid along with you initial strike water. Then you add your sparge water. BeerSmith should give you sparge measurements when you click on your BrewDay sheet.

 

[RighteousFire]

Your sparge water is the remainder you need to reach your boils volume. Subtract the weight of your grain in pounds x .1 from your mash water and subtract this from your boil volume.

4.09 - 0.95 = 3.14

Boil volume - 3.14 = sparge water

That is assuming he wants to do a batch sparge. A fly sparge is where you add water slowly as you are draining slowly. You get better efficiency with a fly sparge as opposed to a batch sparge like breck said. Keep in mind a fly sparge should take a long time. I did one today and I was told at my LHBS that it should take like 45 min.

 

[RighteousFire]

It takes as long as you need it too, based on your efficiencies.

After awhile, my time becomes more valuable than 5% efficiency.

My double batch sparge 80-85% laughs at fly sparging. My conversion efficiency is around 91-95% usually so I'm still trying to get 100% on that part.

You are right I did just kinda assume he was batch sparging. Sorry about that.

damn, duh. thanks for the info. probably shouldnt be doing my prep work now, my first batch in a keg + nba playoffs = me a little pissed while getting ready for upcoming brew.
