What it does :
This device holds a heavy glass carboy securely in an unbalanced position so that it can drain and dry.
What it is:
A carboy drain is a support that holds a glass carboy in an upside-down position.
How it works:
After dutifully scrubbing clean the inside of your glass carboy, it is helpful to have something nearby to drain it upside down without it rolling away and possibly breaking.
A carboy drain does not come into direct contact with the wort and so should merely be kept clean.
