Fermentation Tank Utilization at 98% target cellar utilization: a worked example

What does the result look like when target cellar utilization reaches 98%? The full calculation is worked below with real intermediate numbers. a beverage producer needs to check whether fermenters and brite or conditioning tanks have enough available capacity for the production plan

The inputs for this scenario

  • Occupied fermentation tank-days: 186 tank-days (unchanged)
  • Available fermentation tank-days: 240 tank-days (unchanged)
  • Target cellar utilization: 98 % (raised for this scenario; the documented default is 85)

Working through the calculation

  • Applying the documented formula (Fermentation tank utilization = occupied fermentation tank-days ÷ available fermentation tank-days × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 77.5 % tank utilization for fermentation tank utilization, the number this scenario is built around.
  • At this operating point the engine returns 20.5 points for utilization gap to target.
  • At this operating point the engine returns 186 tank-days for occupied fermentation tank-days.
  • At this operating point the engine returns 240 tank-days for available fermentation tank-days.

How this compares with the baseline

  • Against the tool's baseline example, where target cellar utilization sits at 85% and the headline result is 77.5 % tank utilization, this scenario lands almost exactly on the baseline at 77.5 % tank utilization.
  • A figure at this level is achievable when target cellar utilization is genuinely sustained, not just peaked for a shift. Utilization counts a tank as occupied whether it holds active fermentation or slow-conditioning beer, so a high number can still hide vessels tied up by long-aging product rather than productive throughput.

Results at a glance

  • Fermentation tank utilization: 77.5 % tank utilization (headline result)
  • Utilization gap to target: 20.5 points
  • Occupied fermentation tank-days: 186 tank-days
  • Available fermentation tank-days: 240 tank-days
