Brewing engineer’s FAQ – “Do I need full automation or manual operation?”

Walk into any craft brewery and you will see a spectrum: one brewer using a tablet to monitor every valve, another turning hand wheels by feel. Both can make great beer. But when procurement managers and engineers search for equipment, they often ask: “What level of automation is right for my scale?”

Question: “Is manual cheaper? Yes. Is it better? Not always.”

Manual brewhouses have lower upfront cost and easier maintenance – no circuit boards to fail. But they rely entirely on operator discipline. If your brewer forgets to close the mash inlet valve, you lose a batch. If they misread a thermometer, your mash pH drifts. For brewpubs with one brewer, manual can work well for up to 1,000hL/year.

Question: “What does semi-automation include?”

The sweet spot for most 5–30hL breweries. You get:

Automated temperature control (PID loops on mash and kettle)

Digital flow meters with totalization (no more guessing sparge volume)

Alarms for low glycol pressure or high fermenter temperature

Manual valves for transfer and CIP routing – keeping complexity low.

This removes repetitive errors but still lets your brewmaster feel the process.

Question: “What is the first sign that I need full automation?”

When your operator spends more time logging data than making decisions. Full automation (SCADA with recipe storage, automatic valve sequencing, and batch reporting) pays off at 5,000hL+/year or when you run multiple shifts. It also allows remote monitoring – we have clients who check fermentation curves from their phone while at a beer festival.

Question: “Will automation make my beer taste the same as everyone else’s?”

No – automation does not write recipes. It simply executes your unique parameters with perfect repeatability. The creativity remains yours. The consistency becomes mathematical.

The question that experienced engineers ask

“Can I add automation modules later without changing the control panel?” – Yes, if your panel has spare I/O slots and open-protocol communication (Modbus, Profinet). Our standard panel includes 20% spare capacity. Want to add inline density meters or a DO sensor later? Plug and program.

Your brewhouse should grow with your confidence
Start with semi-auto. Add automated CIP sequencing next year. Integrate a full MES (manufacturing execution system) in year three. We design for that journey – not for a single moment of purchase.
