Don't know if you saw this or not... For Sale - Spike 15G Solo
I just rebuilt my whole system from the ground up, and this was central to the whole process. I have three gallon kegs, so 3G, 6G, or even 9G batches. All equipment was built around that. In the past I brewed 10G and bottled.I have this conversation an average of 3 times a day and it's always amazing how variable the goals can be. I've been trying to put together a standard list of questions. Batch size is a big one and I encourage you to really think hard about it. You will brew more often and get better at it with smaller batches. Can you make 10 gallons of beer disappear once a month? How often do you want to brew? This affects how many fermenters you need.
