four zones · complete brewery.
A Mexican craft brewery has four operational fronts: precise per-tank fermentation, tank-cellar CO₂ life-safety, cold chain for packaged product + raw materials (refrigerated hops), brewhouse energy/steam + CFE GDMTO sub-metering. AstreaIoT covers all four with the same platform.
precise 18-22°C per-tank fermentation
submersible or surface T probe per fermenter (4-20 tanks typical) · continuous fermentation curve log · WhatsApp alert to master brewer if outside ±0.5°C range. Compatible with conical isobaric tanks (glycol jacket); your PLC keeps driving the glycol valve, we alert you.
CO₂ life-safety cellar + brewhouse
multi-parameter sensor with CO₂ per fermentation room + cellar + brewhouse. An alert so your team ventilates + immediate alert when CO₂ rises to 1500 ppm (warning) / 5000 ppm (immediate evacuation). Every alarm is logged: the record that backs your chemical-agent assessment (NOM-010-STPS-2014).
kegs/bottles cold rooms + raw materials
T probe per walk-in cooler of packaged product (kegs / bottles / cans / refrigerated hops). Door sensor + compressor current meter: alerts you when the compressor’s consumption changes. WhatsApp alert if T rises out of range.
steam boiler + CFE GDMTO sub-metering
T probe in steam boiler (95-100°C wort boiling + 80°C sanitization). Three-phase meter on the main panel · per-production-line sub-metering (brewhouse · fermentation · packaging · cold storage). Time-stamped power factor so you decide with data.
Out of scope: brewhouse process control (already in your PLC system). Also no recipes / formulations — that's your master brewer. We integrate with your PLC via Modbus if relevant.
what we protect · what we prevent.
- +Precise 18-22°C fermentation · defended aromatic profile · batches without T-drift defects
- +CO₂ life-safety watched 24/7 · safe personnel · NOM-010-STPS-2014 assessment backed
- +Validated kegs/bottles cold storage · defended freshness · protected brand reputation
- +Steam boiler + CFE sub-metering · power factor in view · consumption per line
- +Backed NOM-142 beer compliance · COFEPRIS inspection with a complete log · defensible brand narrative ("every tank monitored")
- ✕Fermenter out of range 4h overnight · 10-20 hL batch compromised · weeks of lost production
- ✕CO₂ accumulated in cellar · personnel exposed · STPS accident + investigation + possible death
- ✕Walk-in kegs fails weekend · complete inventory at ambient temperature · brand reputation crisis
- ✕Low power factor in GDMTO · invisible CFE penalty · no data to decide on a capacitor bank
- ✕COFEPRIS audit without continuous log · NOM-142 compromise · fine + temporary closure
eight use cases · four critical areas.
for the master brewer + production lead.
Master Brewer + Production Lead + Cellar Manager. Two cases · tank off-range during main fermentation, missed dry-hop window. Aromatic profile + yield.
for the safety lead + plant manager.
Safety Lead + Plant Manager + STPS Lead. Two cases · overnight CO₂ accumulation in fermentation cellar, failed brewhouse ventilation event. Life-safety + STPS.
for the cellar manager + packaging lead.
Cellar Manager + Packaging Lead + Logistics Lead. Two cases · long-weekend walk-in kegs fails, refrigerated hop exposed to ambient temperature. Cold chain + freshness.
for the CFO + plant engineer.
CFO + Plant Engineer + Commercial Manager. Two cases · low power factor in GDMTO, steam boiler with deteriorated efficiency. Energy + costs.
three compliances · one platform covers all three.
For multi-site craft breweries, cross-property dashboard with compliance ranking + consolidated CFE sub-metering.
from sensor to report · every few minutes · without human intervention
Five steps. They run in parallel across all your sites, all the time. When something crosses a threshold, the flow completes in under five minutes — alert delivered, response logged, inspector-ready evidence captured.
measure
Sensors measure temperature, humidity, current, door-open, leak and other magnitudes every few minutes — no operator required.
detect
The system compares each reading against the threshold configured per recipe · per site · per equipment. Threshold crossing triggers the flow.
alert
The alert routes to the right person via WhatsApp, email or push · per role and schedule configured.
respond
The operator acts from the dashboard or mobile app. The corrective action goes into a timestamped log with signature, which can’t be edited.
audit
Everything becomes part of the audit package · time series, critical events, corrective actions, NOM report ready in two clicks.
Five steps · no manual operators · no paperwork · no gaps.
five phases · per brewery.
site survey + brewery plan
1-2 daysTechnical visit + inventory of fermenters (4-20 typical), tank cellar, walk-in coolers, boiler, CFE panel · deployment plan with fermentation + life-safety emphasis.
physical installation
2–7 days per sitePer-fermenter T probes + multi-parameter CO₂ sensor + walk-in cooler probes + CFE three-phase meter · gateway with backup · without affecting production (between-batches installation).
configuration + PLC integration
1-2 weeks (includes Custom L3 if your brewhouse has Modbus PLC)Fermentation thresholds per beer style + CO₂ alerts (warning/danger) + Modbus integration with brewhouse PLC as a project · the temperature record NOM-142 asks for.
team training
1 dayMaster Brewer + Production Lead + Safety Lead + Cellar Manager + CFO + Plant Engineer · each role trains on their flow.
30 days of support + first audit
30 daysAstreaIoT specialist available · first monthly report with fermentation + life-safety + cold storage + sub-metering · first 100% monitored batch.
For multi-site breweries, per-site deployment with standardized BOM.
common questions · before the quote.
does it integrate with my brewhouse PLC system?
As a project · connection built as a project · Modbus TCP or RTU with your PLC (Siemens S7, Allen-Bradley, Schneider). Fermentation + cold storage + sub-metering data feeds your central system. Integration time 2-4 weeks first time · reusable for future expansions.
what precision do the fermentation probes have?
Precision submersible T probes · each probe arrives with its factory calibration report. Surface probes sufficient for tanks with good thermal conduction. The submersible is default for critical fermentation.
what about CO₂ life-safety in cellar with many tanks?
Multi-parameter CO₂ sensor per cellar (the count is set in the site survey) · an alert so your team ventilates at 1500 ppm + immediate alert + do-not-enter alert for the cellar. Every alarm is logged: the record that backs your chemical-agent assessment (NOM-010-STPS-2014). Your personnel protected 24/7.
are COFEPRIS audits for NOM-142 backed?
Yes · the time-stamped temperature record NOM-142 asks for + temperature and energy reports + exportable file · your Responsable Sanitario hands it to the auditor.
how is pricing for a 5-15 hL per-batch brewery?
Per-tank model: SaaS fee per fermenter + cold storage + life-safety + sub-metering. Approximately between hundreds and a few thousand pesos monthly depending on number of tanks + cold rooms + sub-metering. 15–30-day Hybrid Pilot default.
is the "every batch monitored" brand narrative backed?
With data, yes · each tank’s fermentation history is kept 5 years and you export it to show your customers and distributors.
does it integrate with ACERMEX marketplace or network reports?
As a project · the platform sends signed events to other systems; the link to ACERMEX or other networks we build with you as a project.
