Roast Phase Reference Table
| Phase | Typical Marker | Why Track It | Useful Record |
|---|---|---|---|
| Drying | Charge to yellowing | Shows early heat application. | Time, temperature, gas, airflow |
| Maillard | Yellowing to first crack | Supports sweetness and browning control. | Duration and percentage |
| Development | First crack to drop | Helps compare roast balance. | Time and DTR percentage |
| Yield | Green versus roasted weight | Tracks moisture and mass loss. | Weight loss percentage |
| Color | Post-roast measurement | Provides another repeatability check. | Target and actual Agtron |
Why Roastery Batch Sheets Matter
A roastery batch sheet creates one reliable record for every production roast. It connects green coffee details with machine settings, roast milestones, final yield, and quality observations. That connection helps teams compare batches without relying on memory. Clear batch identifiers also improve traceability when coffee moves from storage into roasting, packaging, wholesale orders, and retail inventory.
Use Roast Data for Consistency
Consistent roasting requires more than matching a final temperature. Operators should compare drying time, Maillard time, development time, gas changes, airflow adjustments, and total roast duration. Development Time Ratio shows development as a percentage of total roast time. It is useful for comparison, but it should not replace sensory evaluation. Weight loss also matters because it highlights changes in moisture removal and roast degree. Large differences can indicate a changed profile, green coffee condition, or production error.
Build Better Quality Records
After roasting, the batch sheet should capture appearance, color, cooling performance, defects, and cupping results. Those notes provide context when a roast tastes different later. Recording target values beside actual values makes deviations easier to spot. This generator calculates phase percentages, development ratio, roast loss, yield, target variance, and estimated finished cost automatically.
Support Traceability and Planning
Supplier references, green lot numbers, roasted lot codes, packaging dates, and destinations support practical traceability. Cost fields connect green coffee expense with packaging and other batch costs. CSV exports help with spreadsheets and production analysis. PDF exports create easy batch records for storage, audits, training, or handoff. Consistent records make future roast decisions faster and clearer. Teams can also compare seasonal changes across repeated purchases from suppliers over time. Training records become stronger when new operators review previous successful production batches. Packaging notes connect roast performance with shelf life and direct customer feedback. Regular review meetings identify trends before they become expensive production problems later. Good batch sheets turn repeated roasting into measurable learning.
Frequently Asked Questions
What is roast weight loss?
Roast weight loss is the percentage of green mass lost during roasting, mainly through moisture and volatile compounds.
How is Development Time Ratio calculated?
Development time is measured from first crack to drop. Divide it by total roast time, then multiply by one hundred.
Should every roastery target the same DTR?
No. Development ratio is a comparison tool. Coffee style, machine behavior, batch size, and sensory goals can require different profiles.
Why track green and roasted lot codes?
Lot codes make it easier to trace finished coffee back to the exact green coffee and production roast.
What does Agtron variance show?
It compares actual roast color with the target color. The result helps teams identify lighter or darker outcomes.
Can I export the batch sheet?
Yes. Use CSV for spreadsheet records and PDF for a formatted production document.
