FAQ
What size is the glass vessel?+
The main fermenting vessel has a capacity of 5 litres, approximately 1.8 gallons. It's designed for standard homebrewing batches – typically around 20-30 litres depending on your recipe.
Is this glass suitable for high temperatures?+
Yes, the borosilicate glass is rated to withstand temperatures up to 40°C (104°F), which is more than adequate for most fermentation processes. However, avoid sudden temperature changes to prevent thermal shock.
Does this kit include an airlock?+
No, this equipment set focuses on the fermenter itself. You will need to purchase a suitable airlock separately to allow CO2 to escape during fermentation and maintain an anaerobic environment.
What cleaning products should I use?+
Use food-grade sanitizers specifically designed for brewing or winemaking. Avoid harsh detergents that can leave residues harmful to your final product. Rinse thoroughly after each use.
How do I prevent oxidation during fermentation?+
The airlock is crucial here, preventing oxygen from entering the vessel. Ensure it's properly sealed and functioning correctly throughout the entire fermentation period.
Can I use this for lagering?+
Yes, the temperature resistance of the glass makes it suitable for lagering. However, maintaining consistent low temperatures is critical for successful lagering – consider using a fridge or insulated cool room.
What’s the best way to clean the glass after fermentation?+
Clean thoroughly with hot water and a bottle brush. For stubborn residue, you can use diluted white vinegar, followed by a final rinse with purified water.
Is this suitable for brewing mead?+
Absolutely! The 5 litre capacity is ideal for producing smaller batches of mead, allowing you to experiment with different honey varieties and yeast strains without wasting large quantities.
What’s the benefit of using glass over plastic?+
Glass offers superior clarity, preventing colour distortion and providing a better visual monitoring experience. It's also inert, meaning it won't leach chemicals into your brew, unlike some plastics.
How do I store the fermenter when not in use?+
Store the vessel in a cool, dry place away from direct sunlight. Handle with care to avoid chips or cracks – consider using protective padding if transporting.
