This set of fermentation equipment is designed for use within a standard demijohn – typically holding between 5 and 10 litres. Crafted from durable, food-grade plastic, these components are built to withstand the rigours of home brewing and winemaking. The kit includes all necessary tools for transferring liquids, measuring additions, and controlling temperature during fermentation, providing a robust foundation for successful batch production.
These plastic fermentation vessels are favoured by brewers for their hygienic properties and resistance to breakage compared to glass alternatives. The included components – tubing, airlocks, sparging spoons, and hydrometer holders – are specifically sized and constructed for optimal use within a demijohn environment. This equipment facilitates precise control over the fermentation process, allowing you to monitor temperature fluctuations and ensure consistent results.
The plastic construction also offers advantages in terms of cleaning; simply rinsing with warm water or using mild detergent ensures minimal residue buildup. Remember to always follow manufacturer's instructions regarding sanitation to maintain a clean brewing environment. This kit provides a solid starting point for any home brewer focused on traditional demijohn fermentation.

FAQ
What size demijohn is this equipment suitable for?+
This set is primarily designed for standard demijohns holding between 5 and 10 litres, offering ample space for most brewing batches. Larger demijohns may require additional tubing or components to maintain optimal flow.
Is the plastic food-grade and BPA-free?+
Yes, all plastic components are manufactured from food-grade polypropylene, ensuring they are BPA-free and suitable for contact with fermenting liquids. This prevents contamination and maintains the purity of your brew.
What type of airlock does this kit include?+
The kit includes a standard rubber stopper airlock, designed to allow carbon dioxide to escape while preventing oxygen from entering the demijohn – crucial for maintaining anaerobic conditions during fermentation.
How do I measure additions accurately using these tools?+
The included measuring cylinder and spoons are marked with clear volume graduations. For greater accuracy, use a calibrated hydrometer to monitor specific gravity changes, which directly relate to sugar concentration.
Is the tubing food-safe?+
The tubing is made from PVC (Polyvinyl Chloride) that meets food contact standards and is designed for use in fermentation processes. It's important to rinse thoroughly before first use.
What temperature range does this equipment support?+
Fermentation temperatures will vary depending on your chosen yeast strain, but these plastic components are suitable for a wide range of conditions generally between 18°C and 24°C (64°F - 75°F). Maintaining consistent temperature is key.
Do I need to sterilize the plastic components before use?+
Absolutely! Thorough sterilization is crucial for preventing contamination. Use a brewing-specific sanitizer like Star San, following the manufacturer’s instructions carefully. Rinse well with potable water afterwards.
What are the dimensions of the tubing?+
The standard tubing supplied has an inner diameter of 6mm (0.24 inches), providing sufficient flow for transferring liquids between your demijohn and other vessels within your brewing setup.
Can I use this equipment outdoors?+
While the plastic is durable, it's recommended to store and use the equipment indoors or in a shaded area to protect it from extreme temperatures and direct sunlight which could degrade the plastic over time.
What’s included in the kit exactly?+
This standard demijohn fermentation equipment set includes: 1 x Plastic Air Lock Stopper, 1 x Measuring Cylinder (250ml), 1 x Sparging Spoon, 1 x Hydrometer Holder and approx. 3m of 6mm Tubing.
