Hi all,
Thanks to all of the awesome info on this site, we now have a HERMs system that is almost complete! It consists of 20 gallon HTL and BK, and a slightly larger MLT.
I was hoping someone can help us out with what I assume is a pretty simple question though. When using a recipe for a 5 or 10 gallon batch, how do we properly scale up to 20 gallons? On a high level, one could just assume multiply everything (grain bill, hops, H2O) evenly to get to 20 gallons, but Im not sure that would fly (rather ask first than risk wasting an entire batch under that assumption).
Also, most people seem to fly sparge for 45 minutes. Do you guys generally try to set the flow of the sparge to fill the kettle to the top in ~45 minutes, or is more of a matter of just rinsing the grains for 45 minutes regardless of the final BK level? Obviously it would take longer to fill our 20 gallon kettle at the same sparge-flow rate as a 5 or 10 gallon batch, so if it was a matter of 45 minutes, we would have to have a quicker flow which intuitively doesnt seem right.
Once the first runoffs get to the BK, I assume just sparge until the kettle is at the level of what the recipe calls for (i.e. 20 gallons), right?
Any help is much appreciated. Pics coming soon!
Thanks,
