Fermenter Status
Latest batch per fermenter. A batch is flagged at its endpoint — the last transfer stage present (F-5, beerwell, or F-5→beerwell), falling back to Final — if any byproduct breaches its limit.
Endpoint Ethanol Across Six Months
Every batch endpoint, coloured by feedstock. Breached points turn red once limits are set.
Thin-Slop Watch (Recycling Water)
Daily thin-slop lactic acid coloured by the running feedstock campaign, with a rolling median trend line; red triangles are readings beyond the axis, clamped — hover for the true value. The stepped trace below shows the recycled volume in m³ where recorded (breaks = days with no volume entry), on an aligned date axis. Thin-slop lactic runs naturally higher than batch levels and needs its own thresholds; volume determines its impact on the batch.
Byproducts vs Batch Time
Hours from first fermenter-line sample. Lot samples (ILT/FLT, often drawn on a different clock) and thin-slop are excluded from trajectories but shown in the rail and table. Overlay dashed.

Specific Gravity & pH
SG falling to 1.000 signals reaction completion. Values outside physical range are flagged in the table below.
Samples
Trajectories
One line per batch, plotted against hours from each batch's first fermenter-line sample. Lot samples (ILT/FLT) and thin-slop excluded; breached points enlarge in red.
Stage-by-Stage Comparison
Where a stage has multiple samples, the last is shown. Breaches highlighted; BDL in italics; flagged values marked ⚑.
Endpoint performance by grain — the comparison the plant runs campaigns on. Feedstock campaigns run in monthly blocks (Mar FCI Rice, Apr–Jul Maize-dominant, Aug Maize + Rice).
Endpoint Ethanol by Feedstock — Distribution
Box = interquartile range, line = median, whisker = 1.5×IQR span, red dots = outliers. Flagged rows excluded. Treat boxes with fewer than 5 batches (see table) as indicative only.
Endpoint Lactic Acid by Feedstock — Distribution
Batch results over time — each point is a period mean or median of batch endpoints, for the four key parameters. Use Compare Batches in the Batch Explorer to overlay up to five individual batches.
Ethanol — Daily
Solid line = median, dashed = mean of batch endpoints in each period; the two diverging signals skewed results in that period. Flagged rows excluded. Hover shows the batch count.
Period Summary
Set a lower and/or upper limit for any parameter at any stage — blank means no limit. Limits can be set for all feedstocks or overridden per feedstock (specific beats general). Everything recalculates instantly and is saved in this browser. Send us the exported JSON and it becomes the system's default limits.

What the WhatsApp Alert Would Look Like
Illustrative Phase-3 template message, rendered from the most recent breach.
Plant QC-lab alcohol vs Catalyst HPLC ethanol at batch endpoints, where both were recorded (the lab value is transcribed for only a minority of batches — itself a finding). Units are not defined in the source; a % v/v vs % w/v basis difference could explain part of the gap.
Agreement — Identity Plot
Each point is one batch endpoint. On the diagonal = the two methods agree; the shaded band is your tolerance. Points above the line: HPLC reads higher than the lab.
Divergence Over Time
Percentage difference (HPLC − Lab) per batch by date. The solid line is the mean bias; the band is your tolerance. A drifting cloud means calibration drift, not random noise.
