11L Glass Carboy/Jar/Demijohn for storage and aging of spirits, and wine.
You can also use it as a 11L fermenter if you choose a silicon bung with an airlock.
These 11L glass carboys are great for aging beer/wine as they are completely oxygen-impermeable.
Used by traditionalist brewers who prefer the trusted quality of glass and being able to see your funky batch age.
