Buon Vino stoppers have a longer taper to help produce a better fit and a snug seal, and a lip which prevents them from falling into your container. Available with a 3/8 inch hole for an airlock, or solid with no hole.

#8-9 (medium) size is recommended for medium size barrels and 9 gallon demijohns.
