I have finally decided to step up to AG brewing.
I have read about a HERMS SYSTEM brewing setup........about $4,500.
Any comments on this type of system?
I know many homebrewers but I only know three who bought a preassembled brewing unit. One used it to brew commercially, and the other two use theirs to brew personally. That's not to say that it's a bad investment or anything like that, it's just that they're not the norm. The norm is usually a homemade assemblage of weird things that together happen to get the job done.
If you can spare the $, then one of these systems is actually a pretty good investment, especially if you value your time. Just make sure you step into this with eyes open: the best equipment doesn't automatically mean better beer. Good beer is entirely up to you, but in my opinion is about 95% due to sanitation. The other thing to consider is that you'll probably alter the unit sometime down the road. All 3 of the commercial units I know about were altered in some way once their owners got to know their systems. Most of the alterations were minor but one of the systems doesn't resemble the way it was originally shipped anymore.
If it was me, knowing what I now know, I'd spend the money differently and equip a good double sized (40l finished volume) brewery:
- 142l esky (link
here). I've used both chest-style and cylindrical eskies before, and I prefer the chest style. Fewer stuck runoffs with it.
- Homemade manifold for the bottom of the esky. I'd personally go with a 12mm solid copper pipe model that can be broken down for cleaning but I've heard of people using braided SS with success.
- 60l (if not larger) kettle with tap.
- Propane "king cooker" burner or equivalent.
- If foregoing no chill, you'll need a wort chiller.
- Malt mill with adjustable gap. Motorise it if you wish.
- At least 8 x 19l kegs, but 12 is more manageable.
- CO2 bottle, regulator with dual gauge: tank pressure and regulator pressure.
- Two temperature controlled chambers, one for fermenters and the other for kegs.
You could easily buy everything on the list for a lot less than $4500 and still have money left over for ingredients.
