Here is something interesting for those of you with out of date Fermentis Safspirit Malt.
I was in contact with a supplier over in WA, who was sent this document from Bintani (Australian distributers for Fermentis).
It appears to be a certification to extend the shelf life date from Fermentis.
Neither I or the supplier had heard of this before, but he sent it to me anyway. He was also notified by Bintani, that ALL of their stock is out of date, and it would be highly unlikely to find any in date product available to the public.
For reference, the batch mentioned has an expiry printed on the packet of 11/12/12, and they appear to have extended that to June 2013.
For those with blocks marked with an expiry of Sep 2012, maybe we could assume that they would be just as viable until at least April 2013?
Here's the doc anyway, I had to convert to a jpeg as the forum would not allow pdf or word doc to be uploaded, so hopefully you can read it:
