Tank Turns: The Four Days Nobody's Counting

from The Cold Side · host FermentIQ

Four fermenters, and you want to make more beer. What do you buy? Nothing. You golook at how long beer actually sits in the tanks you already own.Mac and Wren work out what four days off your average tank occupancy is worth on afifteen-barrel system, where those four days are actually hiding (none of them arefermentation), and why the whole thing is worthless if you can't sell the beer.The number: 130 barrels a year. Almost 17% more beer out of the same steel. No loan,no permit.The action: Pull fill-date-to-clean-date occupancy on your busiest fermenter for thelast six months and average it. If that number is more than four days longer than youractual fermentation and conditioning time, you have found free beer.Segments00:00  First Runnings01:15  Hot Side — where the four days actually go07:49  Ask BrewBuddy — "Which fermenter has been occupied the longest right now,       and what stage is that batch in?"09:24  Dry Hops10:15  Last CallMac and Wren are AI voices.
