FAQ
What type of fermentation can I use this 100ml jar for?+
This 100ml glass jar is ideal for small-scale ale, wine, cider or kombucha fermentations. It's sized perfectly for experimenting with fruit wines or trying out different yeast strains before scaling up to larger batches.
What size lid does this jar require?+
The jar typically uses standard fermentation lids designed for smaller vessels, often around 30mm – 40mm in diameter. Ensure your lid is compatible with the jar's dimensions to maintain an airtight seal during fermentation.
Is the glass suitable for high-pressure fermentation?+
While borosilicate glass is strong, it’s best suited for lower pressure fermentations like wine or small-batch ales. Avoid using this jar for highly carbonated beverages where significant pressure build-up could compromise its integrity.
How do I clean the glass jar after use?+
Thoroughly rinse the jar with hot water and a bottle brush after fermentation. Use a gentle detergent if necessary, followed by several rinses with distilled or filtered water to remove any residue before storing.
Does this kit include yeast?+
No, this 100ml trial jar set is designed as an introductory starter kit. You will need to purchase your own yeast strain specifically formulated for the type of beverage you intend to brew – check Amazon UK for a wide selection.
What kind of seals are recommended?+
Rubber or silicone fermentation airlocks are commonly used with this size jar. These create an airtight seal while allowing CO2 to escape, preventing oxygen from entering and preserving your fermenting liquid’s quality.
Is borosilicate glass easier to clean than standard glass?+
Yes, borosilicate glass is more resistant to thermal shock and staining, making it significantly easier to clean compared to regular glassware. It also resists scratching better, prolonging the life of your fermentation jar.
Can I use this jar for mead production?+
Absolutely! This 100ml trial jar is suitable for mead fermentations, particularly smaller batches using honey and fruit. However, ensure you select a mead yeast strain appropriate for the specific flavours you are aiming for.
What safety precautions should I take during fermentation?+
Always monitor your fermentation closely, checking for excessive bubbling or off-odours which could indicate spoilage. Maintaining a cool temperature and an airtight environment is crucial to prevent unwanted microbial growth – refer to specific brewing guidelines for your chosen beverage.
What are the dimensions of the 100ml jar?+
The jar typically measures approximately 12cm (height) x 8cm (diameter), but please verify precise measurements on the Amazon UK product listing before purchasing, as sizes can vary slightly between suppliers.
