Section 3: Glass

1. Usage in Brewing Equipment:
   • Describe the use of glass in smaller-scale brewing equipment, such as carboys or laboratory apparatus.
   • Discuss its transparency, which allows visual monitoring of processes.
2. Limitations and Applications:
   • Highlight its fragility and susceptibility to thermal shock.
   • Discuss its application in experimental brewing or for showcasing beer in taprooms.

Section 4: Plastics

1. Polyethylene (HDPE) and Polypropylene (PP):
   • Discuss their use in brewing for plastic fermenters, tubing, and fittings.
   • Highlight their affordability, lightweight nature, and ease of cleaning.
2. Considerations and Limitations:
   • Discuss potential issues with flavor retention, especially in reused plastic equipment.
   • Highlight the need for careful maintenance and replacement due to wear and tear.

Section 5: Considerations for Material Selection

1. Factors Influencing Material Choice:
   • Discuss factors like cost, durability, ease of maintenance, and compatibility with brewing processes.
   • Highlight the importance of selecting materials based on specific brewing needs and budget constraints.
2. Hygiene and Sanitation:
   • Emphasize the critical role of proper sanitation and hygiene in brewing equipment materials.
   • Discuss how certain materials may require different cleaning and sanitation methods.

Conclusion: Summarize the significance of various materials used in brewing equipment and their impact on brewing processes and beer quality. Encourage brewers to carefully consider material choices based on their brewing goals, budget, and maintenance capabilities.
