Cornelius Fermenter Lids – convert kegs to fermenters

Cornelius Keg Lid for Secondary Fermenter

Cornelius Keg Fermenter Lid via Adventures in Homebrewing.  It has a 3/4″ Hole that’s designed to accommodate a #3 drilled stopper (included) and airlock (also included).  That allows you use a Cornelius Keg as a fermenter.  Use a 5 gallon keg as a secondary for a 5 gallon batch, use a 5 gallon keg as a primary fermenter for smaller batches or use a 10 gallon Cornelius Keg as a fermenter for 5 gallon+ batches.

I have two 10 gallon kegs that I use as primaries.  This allows you to do quite a few things including, easily transfer under pressure, ferment under pressure, carbonate in the primary fermenter and carbonate and serve from the primary (with a cut off dip tube).

    Thanks for sharing this one. Picked up a couple of the used pin lock kegs from them at the $35 price point from HBF, this was the next logical piece.
