FAQ
What type of plastic is commonly used in rubber & plastic fermentation equipment?+
You’ll often find polypropylene (PP) and polyethylene (PE) plastics, both recognised as food-grade. These materials are resistant to acids and won't leach harmful chemicals into your finished product – always check the specific material listed by the manufacturer.
Why is rubber important in fermentation vessels?+
Natural rubber forms airtight seals within airlocks and tubing, preventing oxygen ingress which can lead to oxidation and off-flavours. It’s crucial for maintaining a controlled anaerobic environment during fermentation, essential for desired tastes.
Can I use these equipment with fruit wines?+
Yes, rubber & plastic equipment is generally suitable for fruit wines. However, be particularly diligent about cleaning and sanitising due to the higher sugar content and potential for microbial growth in fruit-based ferments.
How do I clean rubber components after fermentation?+
Use a food-grade sanitizer like Star San or Iodophor – avoid harsh chemicals that could degrade the rubber. Rinse thoroughly with potable water before reassembling the equipment.
Are these materials suitable for high-alcohol brews?+
Generally, yes, but ensure the plastic components are rated for higher temperatures and pressures if you're brewing strong ales or lagers. Consult the manufacturer’s specifications to confirm suitability.
What should I do if an airlock stops working?+
First, check that the tubing is clear of obstructions. Then, ensure the rubber seal is still intact and creating a proper airtight closure – replace if necessary to maintain pressure control.
How does the plastic affect the flavour of my beer/wine?+
When choosing equipment, select food-grade plastics to avoid any off-flavours. Regular cleaning also plays a key role in preserving the purity and taste of your fermented beverage.
What's the best way to store rubber components?+
Store rubber parts away from direct sunlight and extreme temperatures to prevent cracking or degradation. Proper storage will extend their lifespan and maintain their sealing properties.
Are these sets suitable for beginners?+
Most starter kits with rubber & plastic equipment are perfectly adequate for beginners, but careful attention to sanitation practices is still essential for successful fermentation – follow the manufacturer’s instructions meticulously.
What cleaning products should I *avoid* using on rubber components?+
Avoid using strong alkaline cleaners or solvents like bleach as these can damage and degrade the rubber over time. Stick to food-grade sanitizers designed specifically for use in fermentation equipment.
