The wine buyer made the statement from the audience Friday at a seminar at the International Cool Climate Chardonnay Symposium in Niagara, Ontario.
The LCBO tests every wine submitted for sale in Ontario for a variety of faults, including residues of pesticides and herbicides. It does not make its results public, and the buyer told me afterward that it cannot, for fear of being sued. He did not name any of the wines containing cobalt or lead, or their country of origin.
But the public comment is provocative, because if anyone has previously reported cobalt being found in wine, I haven't seen it.
