✍️ Sample CBP Questions & Answers
1. What is 'rickhouse' or 'rackhouse' temperature cycling, and why does it matter?
Natural temperature cycling causes bourbon to repeatedly push into and pull back from the wood, driving extraction of flavors, color, and maturation compounds.
2. What is the recommended frequency for reviewing and updating bourbon history protocols?
Monitoring outcomes through regular data collection and trend analysis is the correct approach because effective bourbon history in the bourbon professional field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.
3. Why is iron content in water considered detrimental to bourbon production?
Iron inhibits yeast health and fermentation efficiency, and can produce off-flavors in the finished bourbon, which is why Kentucky's limestone-filtered water (naturally iron-free) is prized.
4. What is the maximum entry proof at which bourbon distillate may be placed into the barrel?
Federal standards require bourbon to enter the barrel at no more than 125 proof (62.5% ABV).
5. What percentage of a typical bourbon mash bill does malted barley represent?
Malted barley typically comprises 5-15% of a bourbon mash bill, providing sufficient enzymatic power for saccharification while contributing subtle flavor notes.
6. Which factor most directly determines how quickly a bourbon matures in terms of flavor development?
Greater temperature swings and a higher surface-area-to-volume ratio (as with smaller barrels) accelerate maturation by increasing spirit-wood contact.
