Questions brewers ask
How do I schedule fermenters and brite tanks in a small brewery?
Treat each batch as two bookings: a fermenter for its fermenting days plus cleaning, then a bright tank for its conditioning days plus cleaning. The plan that earns the most is rarely brewing your beers in rotation, because a long lager blocks a tank that two ales could use. This tool tries many orders of batches and keeps the one that finishes the most margin by the end of the horizon.
Is the schedule guaranteed to be the best possible?
No. It is a search, not a proof. On small cases it is checked against an exhaustive search and matches or comes close. The page also shows an upper bound that no schedule can beat, so you can see how much room is left; the bound is loose because it pools tank days and cannot see that a 30-barrel batch needs a 30-barrel tank.
What does adding a tank do to the plan?
The tool re-plans with one more fermenter and one more bright tank of your largest size and shows the extra margin over the horizon and per year. That is margin, not profit after the tank cost, and it assumes you can sell what the extra tank makes.
Does it know demand, seasonality or what I can sell?
No. Margin per barrel is the number you type, and the only demand control is the minimum and maximum batches per beer. A beer you cannot sell more of should have a maximum.
Is this brewing, food-safety or regulatory advice?
No. It is scheduling arithmetic on figures you type. Fermentation times, packaging and any licensing, tax or quality questions are yours to confirm.
Not decided
Demand, seasonality, keg and can packaging lines, yeast and brite-tank cross-use, dry hopping or barrel time, fermenters filled by more than one brew, labor, deliveries and rush orders. Each beer's fermenting and conditioning days are fixed numbers, and every batch is assumed to sell at the margin you type.
