Using a kombucha keg for beer?

[scruff311]

I was going to buy a couple of kegs from someone who was using them for kombucha. I'd be using them for beer, but I was hesitant because I wasn't sure if the regular process of PBW + Star San would be enough to make sure there would be no lingering cultures that would re-ferment my beer.

Is there any concern here as long as a normal sanitization process is followed?

I can't say for sure, but when I've made kombucha it never ferments completely dry. And that's all simple sugar. I think any beer yeast will easily outcompete kombucha even if it does linger and infect the beer. (but I doubt it's all that hard to kill with normal sanitization)

Boiling water will take care of anything hiding in there.

I've never made any distinction on what my kegs are used for.
