You walk into a winery and the sound of fermentation fills your ears as the barrels bubble away turning ripe grape juice into wine.
On the top of each barrel is a little gismo that appears to be bubbling away. That’s a barboteur! So what is a barboteur and what does it do?
The word barboteur comes from the verb barboter, a technical word used in the laboratory when dealing with gases that bubble through a liquid.
A barboteur is used as a bung for fermenting barrels of wine. It allows the carbon dioxide to escape while at the same time, keeping oxygen out.
