If you have an extra standard beer keg, with a little effort, you can turn it into a 15.5 gallon stainless steel fermentor. In this video I show you how I did it. Benefits are the adoption of something existing that you have with little extra cost, versus buying expensive kits that sell for a few hundreds of dollars $$$
Not to say that there is anything wrong with them, they are in fact very nice kits, you just end up saving some money.
The beer won’t know any different, it will come out the same…
