IP68 wireless sensors drop directly into any bioreactor or fermentation vessel — no gateways, no rewiring, no downtime.
INTELLIGENT FERMENTATION CONTROL · MEASURED RESULTS
Cut your cooling costs by over 30%.
Cut your cooling costs by over 30%.
No drilling. No change in taste.
SCEPTER holds the exact temperature profile for every batch while shifting the hardest chiller work into the hours with the cheapest energy and the lowest outside temperature. The module installs in 10 minutes on the equipment you already own, delivered a proven 31.4% saving at the Tsarina pilot, and pays for itself within a single harvest.

The Platform
How the control plane works.
From sensor to autonomous control in three stages — a single, hardware-enabled loop that runs any vessel, any process. TSAR is the method — the thermodynamic model, biokinetic profiles and cloud Digital Twin. SCEPTER is the instrument — the bypass module installed on your chiller’s probe line in 10 minutes.
02
Analyze
Real-time telemetry streams continuously to our cloud-native AI engine, modeling every batch as it evolves.
03
Optimize
The automated, closed-loop control plane adjusts temperature and process parameters to guarantee perfect biological outcomes.
The full picture
One loop, end to end. See it move.
No jargon — a live map of the cooling loop. The heat pump chills a glycol buffer; the buffer feeds a closed loop to your tank; SCEPTER commands your existing controller via emulation, coordinated by TSAR Cloud.
Real-world use-cases
Got solar? Outdoor fermenters? Even better.
The same platform, tuned to the modern winery — it turns the sun and the wind into an advantage.
For PV-equipped wineries
Your solar, finally working at night.
SCEPTER moves the chiller — your biggest load — into the cheap, high-efficiency night (COP 4.0) and banks the cold in the liquid you already own. That frees your midday solar to run the presses, lets you sell surplus sun at peak price, and spares your lithium batteries from deep-cycling. Your fermentation profile is never touched — we shift the energy, not the process.
COP 4.0 night · ~2.0 midday
Your wine is the battery — not lithium
For outdoor fermenters
Turn the night wind into free refrigeration.
Outdoor vessels take brutal afternoon sun. SCEPTER’s Meteorological Engine models Equivalent Temperature and wind-chill (Nusselt cross-flow), then harvests cold night air — shutting the chiller pumps off entirely when the wind can hold your setpoint, and pre-cooling before the afternoon peak. Outdoor exposure becomes a free-cooling asset.
Pumps off when the wind is enough
Teq + cross-flow modelled
Got solar and outdoor fermenters? You’re not the exception — you’re exactly who SCEPTER was built for.
Enterprise-Grade Infrastructure
Built pharma-grade. Audit-ready from day one.
The same control plane that guards a fermentation is engineered to satisfy an auditor — immutable records, fail-safe hardware, and autonomy that never depends on the cloud.
FDA 21 CFR Part 11-Ready
Immutable, timestamped BigQuery audit trails. Every AI-driven setpoint change is attributable, reason-logged and tamper-evident — GMP-grade traceability by design.
Solid-State Relay Durability
Actuation switches on SSRs — zero moving parts, no contact wear. Impulse-dosing runs millions of cycles where mechanical relays would burn out.
Edge Offline Fallback
Lose the network and the edge controller holds the line — a local hysteresis loop maintains your exact setpoint until the cloud returns. 0% network risk.
EU Data Residency
Compute and telemetry stay in europe-west4 with per-tenant isolation — GDPR-aligned and ready for enterprise procurement.
The Scale
One Core. Infinite Applications.
The same control plane governs any culture — from precision microbial growth to the most volatile natural fermentation on earth.
Winemaking
Precise control of the temperature profile in the most sensitive and volatile natural fermentation there is.
Primary focusBrewing
Holding strict temperature steps through fermentation and maturation for a guaranteed, repeatable flavour profile.
Food & Dairy
A stable temperature regime across industrial fermentation of dairy and food products.
Biotech & Pharma
High precision and traceability for processes that demand an exact environment for microbial cultures and bioreactors.
Proven in Wine → Global Scale-Up
Winemaking sets our standard. Global fermentation is our scale.
Wine is the most demanding fermentation there is — living, volatile and judged on taste alone. Meeting the winemaker’s exacting standard is what makes the T.S.A.R. Digital Twin exceptional — and the same proven core now powers breweries, dairy, biofuels and the GMP biopharma bioreactors and cold-chain that produce the world’s medicines. Excellence earned in the cellar, delivered across industry.
One proven core · every fermentation50–54%of global pharma output is microbial fermentation
100%of those bioprocesses need precise, continuous cooling
