Diastatic Power
Diastatic Power (DP) is a way to measure how well malted grains can convert starches into sugars during the brewing process. Think of it as measuring the grain's ability to "self-convert" during brewing. It's like a score that tells brewers how active the natural enzymes in the malt are. This is important because these enzymes turn the starches in grains into the sugars needed to make beer. When you see this term in resumes or job descriptions, it usually indicates experience with malt analysis or quality control in brewing. Other similar terms you might see are "enzymatic activity" or "malt modification."

Example Interview Questions
Senior Level Questions
Q: How would you implement a quality control program for monitoring Diastatic Power in a large malthouse?
Expected Answer: A senior candidate should explain setting up regular testing schedules, establishing acceptable ranges, training staff on proper measurement techniques, and creating documentation systems for tracking trends over time.
Q: What factors affect Diastatic Power during the malting process?
Expected Answer: Should discuss how temperature, moisture, germination time, and grain variety affect enzyme development, and how to adjust these factors to achieve desired DP levels.
Mid Level Questions
Q: How do you measure Diastatic Power and what are acceptable ranges?
Expected Answer: Should explain basic measurement methods using standard laboratory equipment, typical ranges for different types of malt, and how these values affect brewing processes.
Q: What problems might arise from malt with low Diastatic Power?
Expected Answer: Should describe how insufficient DP can lead to incomplete starch conversion, resulting in brewing efficiency problems and potential quality issues in the final beer.
Junior Level Questions
Q: What is Diastatic Power and why is it important in brewing?
Expected Answer: Should provide a basic explanation of DP as a measure of enzyme activity in malt and its role in converting starches to sugars during brewing.
Q: How do you record and document DP test results?
Expected Answer: Should demonstrate familiarity with basic laboratory documentation practices, data recording, and quality control sheets.
