Ok everyone I'm looking for ideas and opinions. I'm just starting my homebrew journey first batch is in the fermentor right now but I'm looking ahead. I want to go to all grain biab all in one system eventually but I'm thinking I'd like to stick to a small batch size of 1 to 2 gallons. Has anyone built a 1 to 2 gallon all in one system? I was thinking like a 20 quart kettle a heating element small enough to fit in the pot but high enough wattage to boil. I know the size of any holes put into the kettle would have to be judged carefully so as to not make things to crowded. So what do you all think?
