# Stop Carbonating to the Clock

A lot of breweries carbonate on a deadline. The tank has to be ready for the canning crew, so the gas goes up and someone keeps an eye on the gauge. We think that's backwards. The best carbonation is the slow one that finishes while nobody's watching.

## Fast flow fights physics

Turning the flow up makes bigger bubbles. Big bubbles are buoyant, race to the headspace and never dissolve. At high enough flow you get foam on top of the tank that you can't see, and the only warning is beer dripping into the separator's sight glass ([What's Happening in Your Tank](/bubble-size-physics/)). Rushing doesn't just risk a miss. It wastes the gas you paid for.

## The temperature doesn't sit still

Here's what a rushed run hides. On the 30-barrel plot in [Anatomy of a Perfect Carbonation Plot](/perfect-carbonation-plot/), the product kept cooling all night: from just under 2°C when carbonation started to about half a degree by morning. That's nearly 1.5 degrees of drift.

At a fixed pressure, that much drift is worth roughly 0.1 volumes of CO2 (based on water at 0 to 5°C, [University of Florida IFAS](https://ask.ifas.ufl.edu/publication/FS379)). A short run that stops early locks in whatever the temperature happened to be at the time. A long run that keeps recalculating lands on target.

## Let the run fit your day, not the other way round

The brewer behind that plot set things up so the tank transfer finished in the late afternoon, with flow rates dialled in so carbonation finished just before the crew arrived. Packaging started at 8:30 the next morning. Nobody watched it.

Customers say the same thing:

> "Much less of a time crunch to get the beer transferred, since we can now carb overnight with no worries." Kevin Freer, Block Three Brewing Co.
>
> "I sleep soundly knowing that our beer will be ready for packaging by the morning." Mike Hogan, Upstreet Craft Brewing

## What a long run needs

- **A stone matched to the tank,** so a modest flow still finishes overnight ([Sizing a Carbonation Stone](/sizing-carbonation-stone/)).
- **A controller that tracks temperature,** because the product will keep moving.
- **Alerts,** so if something goes wrong at 2 a.m. you hear about it then, not at tasting ([Remote Monitoring](/remote-monitoring/)).

Set the target, start it when it suits your schedule, and go home.
