Got a free qtr bbl sanke keg

[ChiknNutz]

I picked up a mini fridge for my upcoming fermentation chamber build and was given the subject keg. It has some old beer in it, but seems like I should be able to do something useful with it, just not sure yet. It would make a decent fermenter for 5G batches since it's 7-3/4G or so. Or could use for a standard serving keg, but then have different fittings as I plan to use corny kegs for the most part. Not sure what to do with it since it's non-standard with the rest of my gear. They were just gonna throw it away.

You can remove the spear and use it for a fermenter.
An orange carboy cap fits on the top, or you can get a fermenter kit for NorCal or Brew Hardware that attaches with a tri-clover clamp.

If the chine, the top part of the keg, is stamped with a brewery name, or it is marked in any way, it belongs to the brewery.

I'm using one for both fermenting and bulk aging (bright tank) with this adapter to facilitate oxygen free transfers.
