Five Generations: What Repitching Actually Costs You

Cold Side, Episode 2: Five Generations: What Repitching Actually Costs You Mac and Wren run the math on yeast repitching — liquid versus dry, on a 15-barrel system pitching 52 batches a year, with the cost of a dumped batch written into both calculations. The number that survives depends on whether you can count your generations, and most breweries can't. The number: $51,600 a year on liquid yeast, or $7,525 on dry. Same brewery, same question. Both figures are conditional on tracking your slurry. The action: Find your oldest slurry and write down three things — what generation it is, when it was harvested, and what beer it came out of. If you can't answer all three, buy fresh.
