Anyway my wife found a keg near her work just lying in the park. It was still there 2 days later so I went and picked it up.
I know nothing about kegs and it appears to be a commercial style 50l keg at first glance. Does anyone know what this keg is and is it useful to a homebrewer.
If it is useful what sort of cash outlay would be required to get something setup to utilize this keg???
See the photos below.
