The Kilner 3 L Fermentation Set is designed for larger batch fermenting, making it ideal for preserving seasonal harvests or preparing multiple servings of probiotic-rich foods in one go. Whether you’re making sauerkraut, kimchi, pickled vegetables or fermented condiments, this set offers a reliable, reusable system that simplifies the process.

Included in the set is a generous 3 litre Kilner glass jar, a silicone lid, a traditional two-piece airlock system that fits into the lid, two ceramic fermentation weights, and a detailed instruction and recipe booklet. The airlock allows carbon dioxide to escape while blocking oxygen, supporting a stable anaerobic environment ideal for long ferments. The two-piece design is particularly suited to handling the larger gas volumes that come with bulk fermentation, helping to maintain clarity and texture in your finished product.

This 3 L set offers immediate benefit by allowing you to ferment larger quantities without compromising control. It provides a personal advantage by reducing the frequency of batches and making the most of your time and ingredients. From an ecosystem perspective, it encourages low-waste living and supports food preservation at home, reducing reliance on mass-produced alternatives. With its generous capacity and thoughtful design, this is a solid choice for home fermenters who are serious about quality and scale.

Fermented foods made with live cultures offer a powerful boost to gut health by increasing the population of beneficial bacteria in the digestive system. These microbes support nutrient absorption, improve digestion and help restore the gut microbiome after periods of stress or antibiotic use. A healthy gut also contributes significantly to immune strength, with up to 70% of immune function linked to gut health. Regularly consuming home-fermented foods can improve your body's natural defences, reduce inflammation, and support overall resilience. This makes the Kilner 3  Fermentation Set not just a food tool, but a valuable contributor to long-term wellbeing.
