Master Brewer Certification Inventory Management & Supply Chain 3 — Questions and Answers
Question 1: A craft brewery receives a malt shipment that fails its internal moisture specification but the COA shows it within limits. What is the BEST immediate action?
- Use the malt immediately before further degradation occurs
- Place the lot on quarantine hold and notify the supplier with counter-data (Correct answer)
- Return the entire shipment without testing further
- Blend the lot with compliant malt to average out the moisture
Correct answer: Place the lot on quarantine hold and notify the supplier with counter-data
Quarantining the suspect lot and sharing counter-data with the supplier initiates a formal non-conformance process without disrupting production prematurely.
Question 2: Which type of purchase contract locks in a set price for hops over a multi-year period, protecting the brewery from spot market price spikes?
- Spot contract
- Forward contract (Correct answer)
- Consignment agreement
- Net-30 open account
Correct answer: Forward contract
Forward contracts establish a future price and quantity at the time of signing, shielding the buyer from market volatility.
Question 3: In a brewery's supply chain, 'lead time' most accurately refers to which time span?
- Time from brew day to package date
- Time from placing a purchase order to receiving usable inventory (Correct answer)
- Time from raw material receipt to finished goods transfer
- Time from sales order to customer delivery
Correct answer: Time from placing a purchase order to receiving usable inventory
Lead time is the elapsed time between issuing a purchase order and having the ingredient available for use, critical for planning reorder points.
Question 4: A brewery tracks its yeast slurry usage across multiple fermenters. Which inventory unit is MOST appropriate for yeast cell tracking?
- Pounds per batch
- Cells per milliliter or pitching rate (million cells/mL/°P) (Correct answer)
- Gallons per fermenter
- Colony Forming Units per gram
Correct answer: Cells per milliliter or pitching rate (million cells/mL/°P)
Yeast is managed by cell count and viability relative to wort volume and gravity, making cells/mL/°P the standard unit for consistent pitching.
Question 5: Which analysis technique helps a brewery prioritize which SKUs to manage most tightly based on their relative revenue contribution?
- ABC analysis (Correct answer)
- SWOT analysis
- Pareto chart of defects
- Ishikawa diagram
Correct answer: ABC analysis
ABC analysis classifies inventory into A (high value), B (moderate), and C (low value) tiers so management effort matches financial impact.
Question 6: A brewery's supply chain manager wants to reduce dependence on a single CO2 supplier after a regional shortage. This strategy is called:
- Vertical integration
- Supplier diversification (Correct answer)
- Demand aggregation
- Safety stock elimination
Correct answer: Supplier diversification
Supplier diversification spreads sourcing risk across multiple vendors, ensuring supply continuity if one source fails.
Question 7: When a brewery uses a 'pull' production system, raw material orders are triggered by which event?
- A pre-set calendar schedule created months in advance
- Actual consumption or downstream demand signals (Correct answer)
- The procurement department's quarterly forecast
- Supplier promotional pricing windows
Correct answer: Actual consumption or downstream demand signals
Pull systems replenish inventory in direct response to actual usage or customer demand, minimizing overproduction and excess stock.
