Coffee, Tea, Roasting & Dry Goods Processing calculator

Cupping Sample Rate Calculator

Use this calculator to track sensory coverage for green coffee, roasted coffee, tea lots, spices, or dry goods that require taste, aroma, or defect review. It helps QA decide whether enough lots were sampled before release or purchase decisions.

What this calculator does

  • Calculate cupping sample rate from cupped lots or batches, total lots or batches, and target sampling rate.
  • monitoring cupping, tasting, or sensory sampling coverage
  • The result shows whether sensory coverage meets the release or purchasing requirement.

Formula used

  • Cupping Sample Rate = cupped or sensory-reviewed lots ÷ total lots or batches in scope × 100
  • Gap to target = target cupping sample rate - cupping sample rate

Inputs explained

  • Cupping Sample Rate affected amount: undefined
  • Cupping Sample Rate total amount: undefined
  • Cupping Sample Rate target rate: undefined

How to use the result

  • Use it when managing QA release, green buying, supplier approval, or customer complaint prevention.
  • Treat the result as a planning estimate until it is checked against actual roast logs, green and finished weights, moisture readings, grinder or blender records, packaging checkweigher data, lot traceability, labor reports, utility bills, and released production records.

Common questions

  • What is the cupping sample rate calculator for? It calculates the percentage of lots or batches covered by cupping or sensory review.
  • What information should I enter? Use reviewed lots, total lots in scope, and the target sampling percentage.
  • What does the result tell me? The result shows whether sensory coverage meets the release or purchasing requirement.
  • When is the result only an estimate? Treat the result as a planning estimate until it is checked against actual roast logs, green and finished weights, moisture readings, grinder or blender records, packaging checkweigher data, lot traceability, labor reports, utility bills, and released production records.
