Urban legend involving beer

Factual Questions
1

I once heard a story about a beer that was brewed with an ingredient that helped to treat a local (genetic) disease.

The ingredient was unspecified, the disease, if named, was not retained. Here is all I remember:

Was probably in the UK.
The beer might have the word Spring in the name.
It may have been a wheat beer.
Only 18 people in the world had the disease.
The ingredient helped ease the symptoms.
Was possibly brewed by monks.

OK, there we have a lot of ifs, maybes and misremembered things. I can’t find anything at all online regarding this. I’m starting to think I may have dreamed it. (This isn’t too far fetched, I dream some weird stuff.) Anyone know anything at all about this?

send me a sample of the beer and I may be able to remember it. It’s right there on the tip of my left frontal lobe.

Don’t know about that but there is a beer brewed in the Shetlands (or Orkneys) which involves using cow shit. It is called “poo brew”.

I would have guessed Cow-Orker Lager…
