So I have a very basic grain bill for an IPA:
12.5# 2Row (US)
1# Crystal 60l
.75# Carapils

And what i want to do, is to do a regular size mash, and then split the wort into 5 batches and do 5 different boils. My plan is to do 5 different single hop IPAs and try and really get a feel for what each hop attributes at different boil times and dry hops. Anyways beersmith tells me that to do a 60 minute boil and to wind up with 1 gallon I need to start with 3.21 gallons. Im not sure if this is going to work or not. Should i try and do what beersmith says, and just run some extra sparge water through the mash tun, to get 15 gallons? Or make beersmith think that its a 5 gallon batch and just say that it needs 8 gallons preboil and then split that into 5? Trying to brew either tonight or tomorrow. Have my starter on the stir plate. Any advice tips or help would be much appreciated. Thank you!

I would try boiling some water in your planned pot first, and see what your boil off is. I would expect a boil off of about 1.25 gallons per hour in most cases.

Once you boil your water and see how much boils off in an hour, then you can know what your preboil volume needs to be.

I shall try that here shortly, But lets just say i boil off 1.25 gallons in the hour, so i would need 2.25 * 5 = 11.25 gallons. Should i be able to successfully sparge that much without having any adverse effect?

Ideally, you'd put no more than 3 quarts of water per pound of grain through your grainbed, but I have successfully done 3.5 quarts/pound total. That should give you a little wiggle room!

Up at 5 this morning, finished the 5th batch at 1:30 this afternoon. Quite a hectic morning. Aside from over boiling the first one, I would say that everything else went as smooth as possible. Still haven't gotten the energy to clean up from it all! :-/

GREAT picture! That's awesome.

I'm so much lazier than you that I never even considered 1 gallon batches except for wine! Good job. Let us know how it turns out.

I've been considering breaking up a five gallon batch like that as well, I really like your single hop IPA idea. My idea was to make a five gallon batch and spilt it up post boil, with the variables in the fermenter such as dry hopping or cold steeping grains or coffee and seeing how they changed compared to a non adjusted batch. My fiances sister got me an awesome book that has tons of recipes for one gallon batches, many of them very unusual and interesting. Its called The Brooklyn Brew Shop's Beer Making Book: 52 seasonal recipes for Small Batches. Thought you might like that since you are experimenting with one gallon batches also. Cheers and good luck with your experiment!

This was also my first attempt at using a yeast starter from harvested yeast. Turned out well. All of them are bubbling away like crazy. I used Mr. Malty's Calculator, but went a little higher on the concentration just to make sure that it would work (i was a little nervous). Made a 2L starter and split it into 5 400mL batches and then pitched. I will keep posted on how everything turns out. And i will definitely check out that book. Seem to be right up my ally!
Cheers

Sheldon

With the same base wort, it suprises me that the beers have such a range of colors to them. Is this actually the case? Or is the lighting playing tricks on me? Or maybe hops have a Lovibond rating I wasn't aware of? With all those trub layers, I imagine you pitched a fair amount of time before this pic?
