32 Oz Anaerobic Fermentation Kit

A complete 32 oz (946 ml) anaerobic fermentation solution comprising a thick-walled transparent glass jar, stainless steel fermentation lid with silicone gasket, food-grade polycarbonate airlock, and solid glass fermentation weight. Jar capacity is calibrated to hold standard 2–3 cup vegetable prep volumes, ideal for household-sized ferments. Dimensions: ~15.5 cm tall × 8.5 cm wide; weight approx. 680 g. The glass is non-reactive and scratch-resistant, preventing off-flavours or leaching into acidic ferments. The airlock requires only plain tap water filled to the midpoint — no oils or additives — and reliably vents CO₂ while blocking airborne yeasts, bacteria, and dust. Once fermentation slows (typically after 3–10 days depending on ambient temperature), the silicone plug on the lid converts the jar into a sealed storage vessel for fridge use. Compatible with all traditional lacto-fermented recipes including sauerkraut, kimchi, beet kvass, and fermented garlic. Designed for UK homes where space, safety, and simplicity matter — no external power, no complex calibration, just proven passive fermentation control.
