Batch size

[tommy24a]

Setting up a Spike Trio 20 gal system. Most of the recipes I see are for 5gal batches. How do I go about increasing the batch size to around 15 gal or even 10. Have only ever done 5 gals with my old propane setup. Thanks in advance.

Basically, you scale everything up linearly, except for water. Some portion of your water is more or less a constant (e.g. the amount that will boil off, or the amount lost in in mash tun dead space and/or kettle dead space).

So, if you know how much total water you needed for a 5 gallon recipe...
- subtract the "constants"
- take the answer and scale it up for the new batch size
- re-add the constants

Or use brewing software.

ETA: Since you are setting up a new system, this will be a little trickier, because you'd subtract the old setup's constants and add the new setup's constants.

For 10 gallons I just double a 5 gallon recipe has worked well for me for several years now.

relax, sometimes i brew 10 gallon batches with nothing but 2-row.....you'll get a feel for what "works".......
