Brewing & Fermentation Automation

Eliminate temperature drift with PID-controlled glycol systems and get a real-time view of every vessel in your cellar — all logged for QA.

The Problem

Temperature drift during fermentation

Even a few degrees of drift during critical fermentation stages can produce off-flavors and ruin a batch.

Manual glycol valve control

Manually opening and closing glycol valves to hit target temps is time-consuming and imprecise.

No visibility into multiple vessels

Monitoring fermenters, bright tanks, and conditioning tanks individually means no single picture of your cellar.

No audit trail for QA

Without logged fermentation data, tracing a quality issue back to a specific temperature event is impossible.

How LoopString Solves It

PID-controlled fermentation

On-edge PID loops drive glycol valves to hold fermentation temperature within ±0.1 °C of setpoint — no cloud dependency.

Multi-vessel real-time dashboard

See temperature, pressure, and flow readings from every fermenter and bright tank on one screen.

Crash & diacetyl rest alerts

Configure alerts for temperature setpoint changes so your team is notified the moment a rest phase begins or ends.

Fermentation logs for QA

Full sensor history lets you trace any quality issue to an exact temperature profile and reproduce your best batches.
