Process problem
Frame an attenuation enquiry with comparable records
Agree what is being measured and where in the brewing process the change is needed.
Start with the observations
Define the measurement
State which attenuation measure and analytical method are being used. Record sampling time and process stage with each result.
Describe the baseline
Identify the raw materials and relevant mash and fermentation conditions. Note changes between the baseline run and the run under review.
Agree the trial boundary
Specify where a treatment is proposed and what outcome would justify further evaluation. Confirm the intended use and current guidance for any candidate product.
Keep attenuation figures on the same basis
Review the fermentation record before changing a product or process.
Confirm the reported metric
Identify the measurement and calculation, including whether attenuation is apparent or real. Use the same basis for reference and trial, with instrument and sampling details.
Compare the process histories
Document recipe, mash schedule, yeast and fermentation temperature history. Mark changes between batches; a different endpoint alone does not show which change caused it.
Agree the quality boundary
Include the finished-product requirements used by your team. Decide in advance which process and quality checks must pass before a trial is considered useful.
Bring the brewing evidence together
Provide enough context to distinguish a measurement question from a process question.
Starting conditions
Send recipe and wort records with the relevant batch identifiers. Describe preparation and any departure from the usual process.
Fermentation profile
Include time-stamped readings, temperature records, method details and the stated endpoint. Explain missing data or changes in sampling practice.
Review request
State the desired outcome and constraints. If the enquiry concerns a non-brewing fermentation, use the fermentation support page so the review starts with the correct process context.

A step-by-step review example
Illustrative review sequence for content demonstration. The observations below are hypothetical branches, not a diagnosis or a verified customer case.
| Decision point | Possible observation | Next check | Decision to document |
|---|---|---|---|
| Are the figures on the same basis? | Measurement or calculation differs | Align the reporting basis | Reassess the apparent difference |
| Did the upstream process change? | Recipe or mash history differs | Compare the relevant preparation records | Separate the upstream question |
| Is the time profile different? | Comparable measurements show a changed profile | Review actual fermentation history and quality constraints | Define the next controlled check, not an assumed enzyme remedy |
