• Incoming raw materials
• Washing and sanitizing equipment
• Fermentation and storage
• Packaging and labeling
• Transportation and storage

2. How do you ensure that yeast is viable and active before pitching?

Microscopic examination

• Examine yeast cells under a microscope to assess their size, shape, and motility.
• Check for signs of contamination or damage.

Wort viability test

• Pitch a small amount of yeast into a sample of wort and measure the fermentation activity.
• Compare the results to a standard or reference value.

3. Describe the process of wort cooling after boiling.

• Use a wort chiller to rapidly cool the wort to below 100°F (38°C) to prevent caramelization and microbial growth.
• Aerate the wort during cooling to provide oxygen for yeast growth.
• Monitor the temperature and adjust the flow rate of the cooling water as needed.

4. How do you maintain a sterile environment during fermentation?

• Sanitize all equipment before use.
• Use aseptic techniques when pitching yeast and sampling wort.
• Control temperature and humidity to minimize the risk of contamination.
• Monitor for signs of infection and take corrective action if necessary.

5. What are the potential causes of off-flavors in beer?

• Contamination by bacteria or wild yeast
• Exposure to oxygen or light
• Improper fermentation conditions
• Use of inferior ingredients
• Equipment malfunctions

6. How do you troubleshoot and resolve problems during fermentation?

• Identify the problem by examining the wort, yeast, and fermentation vessel.
• Research potential causes and consult with experts if necessary.
• Implement corrective actions, such as adjusting temperature, adding nutrients, or repitching yeast.
• Monitor the progress and make further adjustments as needed.

7. Describe the different types of filtration used in beer production.

• Depth filtration: Removes particles by passing the beer through a bed of filter media.
• Membrane filtration: Uses a semi-permeable membrane to separate particles from the beer.
• Crossflow filtration: Forces the beer through a membrane while simultaneously removing particles.

8. How do you ensure that bottled or canned beer is properly carbonated?

• Calculate the desired carbonation level based on beer style and packaging type.
• Add sugar or priming solution to the beer before packaging.
• Control temperature and storage conditions to promote slow and even carbonation.
• Monitor carbonation levels using a pressure gauge or other appropriate method.

9. What are the key safety considerations in a vat house?

• Proper handling of chemicals and cleaning agents
• Equipment safety, including guarding of moving parts and lockout/tagout procedures
• Safe lifting and handling practices
• Slip and fall prevention
• Emergency response plans
