As colder temperatures set in, proper storage of brewing ingredients becomes crucial to maintain product quality and effectiveness. Two particularly sensitive components—isinglass and enzymes—require special attention in winter. This guide will help you understand best practices for storing these products safely through the season.
Isinglass: Handle with Care
Isinglass is highly temperature sensitive. To preserve its properties, always:
- Store in cool conditions away from direct sunlight.
- Keep containers sealed when not in use.
- Maintain storage temperature between 5–15°C (41–59°F).
- Never allow the product to freeze (minimum temperature: 1°C/34°F).
- Observe a shelf life of 8 weeks from the date of manufacture at recommended temperatures.
Following these steps will help you maintain the effectiveness of isinglass in your brewing process. Always refer to your product’s technical datasheet for specific storage instructions.
Enzymes: Cold Storage is Critical
Enzymes are proteins that act as biological catalysts, essential in brewing and other beverage production. Because they are so reactive, enzymes are prone to degradation and decay if not stored correctly, especially in winter months.
Key guidelines for enzyme storage:
- Most enzymes should be kept in dedicated laboratory refrigerators or freezers, depending on type.
- Enzyme storage temperatures typically range from -10°C to -25°C (+14 to -13°F), but always check your technical datasheet for specifics.
- Enzymes denature and lose efficacy at higher temperatures.
- Avoid repeated freeze-thaw cycles and minimise humidity exposure.
Different Enzyme Types, Different Needs
There are six main classes of enzymes—oxidoreductases, transferases, hydrolases, lyases, ligases, and isomerases—each with unique storage requirements. Some may require ultra-low temperatures (-70°C or lower), while others remain stable at -20°C for extended periods. Carefully read manufacturer guidelines and invest in reliable, high-performance laboratory refrigeration to protect your valuable enzyme stocks.
Why It Matters
Improper storage of isinglass or enzymes during winter can compromise your brewing results and lead to unnecessary waste. By following best storage practices and consulting technical datasheets for each product, you can ensure consistent quality and extend the shelf life of your ingredients.
Stay vigilant this winter—your brews will thank you!
