So this weekend (thanks to a generous infusion of cash from a friend who loves my beer), I will be venturing from the waters of PM to AG. I am going to be doing Ed's Haus as it seems a safe bet for a first batch!

Just wondering how you calculate volumes for batch sparging? And temps?

Also, would it be prudent to keep a pound of DME around in case efficiency is crap?

I CANT WAIT!

Try ProMash (What I use) or BeerSmith. I bought ProMash, but the demo works forever, you just cant save anything or do inventories and such (I think this is right). Beersmith has a 30 day or so trial. Those will give you what you need.

Some DME is never a bad idea on your first AG.

beersmith, free 21 day trial.

and yes.

do you know how much you'll need in the kettle for your pre-boil volume? work backwards from there. lets say its 7 gallons for a 5.5 gallon batch. and lets also say you've got 10 lbs of grain. if you do a single infusion at 1.25 qt/lb you're adding 12.5 qts (3gallons, 1 pint). the grain will absorb about .1 gallons of mash water per pound, so you'll lose a gallon to the grain. if you don't mash out with another infusion to bring your grain bed temps up to sparge temp, and you have zero dead space in your mashtun (unlikely) then your first runnings will be 8.5qts. you need 7 gallons (28qt) in that kettle, so you've got 19.5 qts to go. i do a mash out and double sparge, so i usually divide what's left in two, but give a little extra to the first sparge, because that wort will have more sugar in it. if your MLT (i'll presume you're using a cooler) can hold the whole 19.5 qts put it in, stir, and drain. you've got the 7 gallons needed. if you'd like better efficiency i'd recommend a double sparge, so maybe use 11qts for the first, and 8.5 for the second. don't worry about absorption, the grains all soaked up what it can. you do need to worry about dead space. either ignore it or tip your cooler. ignoring it drops you efficiency because you're leaving sugar behind. tipping your cooler risks stirring up some grain that will end up in your boil, possibly causing tannin extraction or clarity issues. use beersmith or one of the online calcs to figure temp. expect to not hit any of your temps. keep lots of notes. good luck!

In short - I tend to have 5 gallons of sparge water ready....

you'll know after your mash runnings how much you'll need, but I like having 5 gallonns ready at temp since the mash runnings calculation has some variables....

Definitely use a brewing program for your first batch. Take the time to get familiar with it too before you brew....like right now. it helps to know your way around all the tools on Beersmith, for example

If you don't want to pony up the cash for brewing software just yet, there are online calculators out there:

Like this one

And yes, have some DME handy. If nothing else, you can use it for a starter for your next batch.

Springer: That is an amazing online calculator. I couldn't believe all the info it gives you! That thing should be in everyone's favorites. Wow, great find!

I highly recommend you write out or look up an existing "brew script." Like the exact steps you will follow, from waking up and sanitizing your gear to cleaning up and putting everything away. Try to get as granular as you can, and you'll uncover every piece of information you need to get everything going. Have fun!
