In 2016, beer testing in Germany revealed residues of glyphosate, a suspected carcinogen, in every sample of beer. The environmental organization EcoWatch has found glyphosate in all of the most popular brands of wines in America and the world. One common factor in the tests is the presence of Monsanto Roundup, which is commonly sprayed in vineyards. Glyphosate herbicides do not dry, wash or cook-off. They have also been proven to be neurotoxins, endocrine disruptors and a cause of liver disease even at very low levels.
