Glyphosate found in organic beer and wine, research reveals. To conduct the test, researchers evaluated 20 samples of domestic and imported wines and beers, all sold in the United States. Sampled wine brands included conventionally-grown varieties such as Barefoot, Beringer, and Sutter Home. And, yes, two organically grown wines, Frey and Inkarri Estates, were included. In terms of beer, researchers looked at Coors, Corona, Heineken, Sam Adams, Stella Artois, and Tsingtao. A pair of organic beers, Peak and Samuel Smith, were tested as well. Disturbingly, all samples of the beverages contained glyphosate – albeit in varying levels.
