Thanks for the answers, and some of the questions :
Biggles : It's not the water content of the honey, more to do with any other chemicals picked up from the environs.
Midland Beek : It's nothing specific, its just there is a lot of industry in the area and a lot of stuff that isn't 'natural'. I'm a little concerned about what the plants pick up from the local water and therefore what gets into the honey.
VEG : Nothing specific really, I just want to be sure that I'm not poisoning my friends/family
I was just wondering what the big sellers do. Do they just ship the honey out hoping that it doesn't have lots of heavy metals in it or some other 'nasty'. So I was wondering if anyone knew of a lab that would test a sample and give me the thumbs up to say it is ok.
