Assuming a decent brewer, I think it is important to think of batch as just another brewing method. As far as the actual brewing process goes, a Fetco & a V60 have more things in common than they have differences!
With that being the case, it comes down to a few things:
1 Buying good coffee to batch brew.
2 Programming the machine to output water with a bloom stage and 2 or 3 dispensing stages.
3 Keeping the equipment very clean. We would never serve coffee brewed with a dirty v60 into a dirty cup. Clean your spray heads, brew baskets, and pots with cafiza once a day and rinse them very well between each brew.
4 Stirring or shaking the pots after you finish brewing them. Stratification during brewing is real- the coffee at the bottom of the pot will taste quite a bit different than the coffee at the top unless you mix it up.
5 Dialing it in. Start with a 5 minute dispensing time, medium grind, and 120g of coffee for a half gallon. That should make a pretty legit pot of coffee that you can feel good about selling while you fine-tune it. Taste a bit of each pot you brew and make minor adjustment according to extraction flavors (grind) and desired strength (dose). If you only change one variable slightly each time, you should end up with an optimized brew recipe very quickly.
