Ferment & Wash agent

Fermentation trajectory control for temperature, gravity and Brix, pH, and yeast health, tuned toward the target congener and ester profile before distillation begins.

What it does

Caskent models each wash as a live biochemical trajectory, then keeps the fermenter inside the temperature, sugar conversion, pH, and yeast-health envelope selected by the distiller.

  • Forecasts gravity fall and heat generation across the run.
  • Detects stalls, stress, nutrient drift, and contamination signals early.
  • Shapes ester and congener precursors before they reach the still.

How it works

The agent fuses fermenter telemetry, lab checks, recipe intent, and historical runs. It recommends or applies bounded adjustments to jackets, cooling schedules, nutrients, and transfer timing.

  • Shadow mode compares planned and actual trajectory.
  • Assist mode proposes operator-reviewed actions.
  • Graduated autonomy acts only inside approved limits.

Capabilities

Control features built for wash consistency and upstream quality.

Trajectory forecast

Predicts final gravity, completion time, thermal rise, and ester precursor range from live signals.

Thermal control

Tunes jacket schedules and ramp limits to protect yeast while keeping production on plan.

Health detection

Flags stuck fermentation, stress, nutrient deficit, and contamination patterns for review.

Recipe protection

Keeps site recipes, yeast programs, and sensory targets isolated to the tenant.

Transfer timing

Recommends when wash is ready for the still based on chemistry and operations constraints.

Inputs and signals

Every recommendation is grounded in signals your team can inspect.

SignalSourceWhat Caskent does

Gravity / BrixInline, sample, or lab readingsForecasts attenuation and detects stalls before schedule risk grows.
pHProbe or lab sampleFlags drift tied to yeast stress, contamination, or recipe mismatch.
Yeast healthViability checks, nutrient data, historical runsRecommends nutrient, cooling, or review actions inside guardrails.

Control sequence

A real ordered loop from model fit to operator-approved action.

  1. Step 1

    Read the wash

    Collect telemetry and lab context, then compare the live batch against recipe and historical envelopes.

    SENSE
  2. Step 2

    Forecast the endpoint

    Predict completion time, pH path, gravity fall, and precursor profile before the deviation becomes costly.

    PREDICT
  3. Step 3

    Act inside limits

    Recommend or apply approved cooling, nutrient, and transfer adjustments, with the operator able to pause the loop.

Outcomes

Illustrative design-partner targets, measured against each site baseline.

18%fewer stalled or delayed fermentations
12%tighter gravity endpoint variance
7%higher ester-target conformance
100%of control actions logged

Assurance note

Ferment & Wash runs under bounded control. Every recommendation and action is logged, grounded in available signals, and reviewable by the distiller. Human-in-the-loop checkpoints stay active across shadow, assist, and graduated autonomy modes.
