So I have a big party coming up and I want to brew 15 gal of beer to fill a sankey keg with. I've decided on brewing Biermuncher's Centennial Blonde, as it will be a big crowd pleaser. I have equipment to brew 10 gal batches...my thought is this:

I put the 5 gal recipe into Beersmith, and then scaled it to 15 gallons. It's a light enough beer that all this grain will still fit in my mashtun. Can I mash/brew 10 gallons this beer (with enough grain in there for 15 gallons)...boil and cool 5 gallons of water, add it to my fermenter (a 20 gallons food grade bucket), and then rack my 10 gallons of extra-strong centennail blonde onto the 5 gallons of water...leaving me with, if logic is serving me correctly...15 gallons of Centennial Blonde, at its proper strength/taste/etc. ?? Is there anything wrong with my plan here?

Thanks!

Would it be easier to brew a 7.5 gallon batch at double strength then add 7.5 gallons of boiled and cooled water to the fermenter? Iím not a big math guy and think this would be easier.

I think that would be the same thing? The scaled recipe I am ok with, I just scaled it in beersmith so I know that's right. My question is that, assuming I scale the recipe correctly, is adding the 5 gallons of boiled and cooled water at the end going to cause any trouble. Again, beersmith did all the math for me, so I know I have the right amounts of grains and such.

I think you can get away with it

You'll have to augment your hops additions because of lower utilization and you might get lower extraction efficiency.

I hear this is what Budweiser does.

Your hop utilization will be different because your wort will be more dense. You'll have to adjust the hop schedule.

How much is a different question.

Should work....might want to guess a few points low on efficiency to account for the extra thick mash/sparge due to the extra grain but no extra water...

Not sure how concerned you are with hop utilization and efficiency but it's called high gravity brewing and it's what most--if not all--the big brewers do.

I would think your plan would be totally fine. It's also what some of us extract brewers are doing as well (me included, currently). Brew a smaller amount of concentrated wort and dilute to the desired fermenting volume.

Let us know how it turns out.

Thanks for the info folks. I feel pretty good about trying it out. I'll report back when its all said and done.

Gonna put 5 gallons on normal co2, 5 gallons on nitrogen, and gonna try to fruit 5 gallons with blueberries

Yeah, I think your biggest issue is that you won't be sparging very much so you're not going to get good grain conversion efficiency. You could always plan it with your normal efficiency and be ready with some DME in case you need to up it a bit. It would be too hard (impossible) to guess how much lower your efficiency would be so this is probably the best bet.

Just out of curiosity, what's your limiting factor? I assume you only have a 15 gallon pot? I did a 10 gallon Barelywine in a 15 gallon pot before by splitting the boil into two pots on two different burners. The bittering additions went into both pots but I poured the wort from both into one pot about 1.5 hours into a 2 hour boil (once some had evaporated) before it was time for the flavor/aroma additions. You could go ahead and sparge for 15 gallons, collect the extra in a bucket, and add it to the main boil as it evaporates. Whatever doesn't fit can go onto the stove and get boiled separately.

I guess what I'm saying is why boil a concentrated wort and water separately and then blend later when you could just as easily boil a concentrated wort (first runnings of the mash) and a weak wort (second runnings) separately and then blend them later.

ajwillys, you're right, I don't think there is any difference other than IMHO convenience. I only have to monitor one boil, add hops to one boil, etc. It seems like it'd be less of a headache to me. I am thinking that no matter which of the above suggestions I use, they will all end up fairly close to the same. Boiling a strong, and a weak wort, then mixing them is pretty much the same as boiling a strong wort and then mixing with water no?
