Rubber & Silicone Bungs, Cork Stoppers
Bungs and stoppers are the cheapest part of a batch and the one that decides whether it survives. A perished bung lets air in slowly enough that you will not notice until you taste it.
Rubber and silicone bungs. Both come bored, with a hole for an airlock, or solid, to seal a vessel that has finished. They are tapered and sold by size range, from 17 mm up to 91 mm in silicone, to suit demijohns, carboys, flasks and barrels. Silicone is food grade, handles heat and lasts longer without going hard, which matters if a demijohn sits for a year. Rubber is the cheaper, traditional option for everyday fermenting.
Special bungs and grommets. A thermometer bung for still columns, an Italian bored bung stopper at 17 mm top and 12 mm bottom, a top hat grommet for fitting an airlock to a fermenter or jar lid, and a rubber grommet for brew fermenter lids.
Cork stoppers. Natural cork stoppers with wood heads at 19 x 28 mm, beige synthetic stoppers, synthetic stoppers at 22 x 28 mm, plastic expandcork at 19 mm, and black plastic flat top port stoppers for fortifieds and spirits. A large rough top tapered cork at 110 mm base suits a wide neck demijohn or a jar, and wood bungs from 12 to 17 mm are the traditional option for barrels.
Two things worth doing. Measure the inside of the neck rather than eyeballing it, because a bung that almost fits is a batch that spoils slowly. And replace bungs on a schedule rather than when they fail, since they cost a few dollars and a demijohn of wine does not.
Bring the vessel in if you are unsure. See also airlocks, corks and capsules and demijohns.

A rubber grommet for a fermenter lid, from Morgans. It seats into the hole in the lid and holds the airlock, giving you a snug fit so the ferment can breathe out without letting anything back in. Grommets perish, go hard and get lost in the bottom of the sink, so it is worth keeping a spare or two in the brewing box rather than discovering on brew day that yours has gone walkabout. Cheap insurance for anyone still fermenting under a standard plastic brew lid, which is most of us.
For still head
$16.00 AUD
A bored bung stopper made in Italy, with a 17mm top diameter and a 12mm bottom diameter. The bore lets you pass a thermometer or tube through while still sealing the neck. Bungs need to sit snugly rather than be forced, so measure your opening against both diameters before ordering. Bring the vessel neck measurement in and we will pick the right one with you.
$2.80 AUD
Top Hat Grommet fits into a drilled or punched hole in your fermenter lid. This allows for a standard handy or bubbler airlock to fit securely into the fermenter, with an airtight seal.

Frequently asked questions
What size bung do I need?
Measure the inside diameter of the neck. Our bungs are tapered and sold by range, such as 25 to 33 mm, so pick the one whose range takes in your measurement, ideally with your neck near the middle of the range. If you are unsure, bring the vessel into Laverton North or Epping.
Should I buy a bored or solid bung?
A bored bung has a hole through the middle for an airlock, blow-off tube or thermometer, so use one while something is fermenting. Our bored silicone bungs have an 8 mm hole for an airlock. A solid bung seals a vessel that has finished, for storage or ageing. See our airlocks.
Rubber or silicone bungs?
Both seal well. Silicone bungs are food grade, handle heat up to 180°C and last longer without going hard, which suits wine stored in a demijohn or barrel for a long time. Rubber bungs are the cheaper, traditional choice for everyday fermenting.
