How to choose the right size

Measure the inner diameter of your demijohn's neck before ordering. Size 3 corresponds to a 35 mm neck and is suitable for 2 to 5-litre containers. For larger demijohns, from 5 to 10 litres, choose size 4 (Ø 45 mm); for 10 to 15 litres, size 4A (Ø 50 mm). This version has no hole; for the active fermentation phase with an airlock, prefer the perforated version (Gärkappe).
