I have a question about old pin lock coke kegs. I have an opportunity to acquire some cheaply, and I'm going to take it regardless of the answer.

But my question is this: are they heat safe enough to receive boiling wort or are they lined with plastic?

They should just be stainless steel, no lining, assuming you didn't get some special version.

They're just stainless steel, but there's a possibility that the tops + bottoms may separate due to the heat. Keep that in mind.

And.. watch out for burnt fingers and legs!

I'm curious why you're putting boiling wort into a keg?

No-chill method? Fermenting in the pin-locks?

Just be careful that you don't suck in any nasties when the wort cools and sucks a vacuum.
I've used a star-san soaked rag over the head of the keg and had no problems, but just be aware that it won't be a closed system until you get internal positive pressure.

A professional brewer friend of mine suggested to me that kegs aren't a great choice for fermentation. The shape isn't good. They're too tall and skinny - he explained that you don't get good circulation. I'm sure you've seen all the movement in your fermenters when the little yeasties are chugging away. The keg won't produce as much of that circulation - which means a slower fermentation.

I won't suggest you don't pick up cheap kegs - I certainly would. But if you're looking for additional fermentation containers what about buckets? They're cheap, durable and a better shape.

Its an issue of temp controlled space, I can fit 1x 6.5 gallon bucket into my cooler, but 4x 5 gallon kegs. Also circulation is nothing a strong starter can't compensate for.

That's interesting, coming from a pro, because when I look at the fermentation vessels in use at the bigger local "micros", the 120 barrel and especially the 200 barrel monsters have an aspect ratio that is actually closer to a 5 gallon corney than the typical fermentation bucket - and even closer than that of a 6.5 gallon glass carboy...

Cheers!
