15 gallon kegs

just got 6 for $90...  beat that!

Yea, but I didn't have to sleep with anyone

Ha ha



 

I have a 13.5 gallon keg which I plan to use to try 10 gallon batches. I also have a ten gallon cooler to mash in...... I currently have a smaller keg/ half keg...( 7.5 gal.or so) that has a ball valve in it and the top cut out. Will that be large enough to heat up the sparge water or do I need to look for a bigger pot to heat water? I would like to set all three up so as not to have to move any pieces while heating/ sparging etc.

 

I think that a 7.5 gallon HLT is going to be too small for 10 gal batches.  Just looked over a number of my own 10 gal recipes and most have over 7.5 gallons of sparge water.

 

I was afraid of that. I got it for next to nothing at the local HBS and the owner stated he thought it would be fine because you would not be heating all the water at once but I think he thought I was doing 5 gallon batches..... How do you calculate how much sparge water you will need? Looks like I may need to use my old brew pot for extra water for now until I can get a larger keg/ pan to heat enough for a ten gallon batch.



 

Bull, it depends on whether you batch or fly sparge for volumes. You basically need to calculate your total batch volume preboil, and subtract for grain absorption. So if you want a 1o gallon batch with a 12 gallon preboil, you will need 12 gallons of total water + the amount that will be absorbed by whtevr volume of grain you use.

If you are close, it is no biggy to throw a couple gallons of water on the stove top and just replenish you HLT or MT as you use up the 7 gallons you have.

Most of my recipes need 9-11 gallons for the mash infusion, then I have 2 5.25 gallon coolers I use for HLTs. Today I did the BKB APA and only had 8 gallons of strike water, so after that was replaced with my 10.5 gallons of sparge water, I would have came up short, but I had a few gallons brought to temp on the stove top, to refill the first HLT, and get me my full 15 gallon runoff.

 

I would love to fly sparge but to get started I think I will batch. I think for now I will stick with what I have and use the stove top or a cooler for additional HL.
