Oh, one more thing.  I might suggest that in passing you mention what happened to your supplier in passing and see if they volunteer to help out in some way.  It could be done in a manner like asking them if they had heard about problems with that batch of maple because...(describe what happened to you).  Maybe they will, maybe they won't.  But if you approach it this way you are unlikely to cause any bad blood and affect your relationship with them.

Just a thought.
