All the horrible chemicals that Agave is exposed to pretty much boil down to inert filtration agents--activated charcoal and mined perlite--inorganic acids, resins (likely another part of the filtration process, and not likely a source of contamination) and enzymes. Not saying the stuff isn't bad for you--it's nectar, hence sugar. But that ZOMG Teh Chemicals!!!!!!!! always gets under my skin. Water's a chemical.

I'll stop now.
