Usage
Before use, the caps should be washed thoroughly with warm water and dishwashing liquid, and then dried completely. This removes the silicone layer left from production, which may cause rubber caps to slip off during wine fermentation.
The caps are highly elastic, which makes it possible to use them on various vessels; they can serve as a tight closure for a wine demijohn or, after cutting off the tip, as a stopper with a hole for a fermentation tube (airlock).
