In my opinion these 5 or 7 barrel systems by Brewha are the best for small operations like mine. Small enough to be easily handled by one person with a harbor freight lift system, but big enough to produce enough beer to supply a small taproom at least.
They’re all electric, so you deal with less red tape than you would with gas. And they’re space efficient since you mash, boil, ferment, and condition all in the same tank.
Cleaning is easy and you don’t need to deal with harsh caustic cleaners since the boil is done in the tank before you drop yeast in it self sanitizes.
They’re a company out of Canada. A little spendy but worth it if space is at a premium where you might wanna brew.
They make small homebrew and pilot systems as well. Use code EntrePRObrewer5 if you’re ever in the market and save 5 percent!
