The Short Answer
Yes, most conventional beers contain trace amounts of glyphosate. When consumer watchdog U.S. PIRG tested popular brands, they found the weedkiller in 19 out of 20 beverage samples.
Tsingtao, Coors Light, and Miller Lite had the highest levels, while only one organic brand tested completely clean. While the detected amounts fall below EPA limits, the findings prove that agricultural chemicals are quietly making their way into your Friday night pint.
Why This Matters
Beer is made from barley and wheat, crops heavily sprayed with agricultural chemicals. Farmers often use glyphosate as a pre-harvest desiccant to dry out the grains quickly. What Is Pre Harvest Glyphosate Spraying
Because the chemical is applied right before harvest, it is absorbed directly into the grain. You cannot wash or brew glyphosate out of the raw ingredients. Why Is Glyphosate In Wheat A Problem
The sheer volume of glyphosate used in modern farming means contamination is now environmental. Even organic beers sometimes test positive for trace amounts because the chemical travels through rain, soil, and irrigation water. Is Organic Produce Actually Pesticide Free
What's Actually In Conventional Beer
Independent testing has consistently found agricultural residues in the final product, meaning you're getting more than just water, malt, hops, and yeast.
- Glyphosate — The active ingredient in Roundup. The World Health Organization classifies it as a "probable human carcinogen."
- Pre-harvest desiccants — Chemicals sprayed directly on barley and wheat to artificially speed up the drying process before harvesting.
- Environmental drift — Cross-contamination that occurs when chemicals from conventional farms blow into organic fields or enter the water supply.
What to Look For
Green Flags:
- Certified Organic labels — While not a 100% guarantee against drift, organic certification strictly forbids the intentional use of glyphosate.
- Independent pesticide testing — Brands that publish third-party lab results proving their products are residue-free.
Red Flags:
- Conventional wheat and barley — Non-organic grains are at a high risk for pre-harvest glyphosate spraying.
- Mass-market imported beers — Brands like Tsingtao have tested with some of the highest glyphosate levels (49.7 ppb).
The Best Options
If you want to minimize your exposure, your best bet is sticking to certified organic breweries.
| Brand | Product | Verdict | Why |
|---|---|---|---|
| Peak Organic Brewing | Peak Beer Organic IPA | ✅ | The only beer tested with zero detectable glyphosate. |
| Samuel Smith | Organic Lager | ⚠️ | Tested at a very low 5.7 ppb, likely from environmental drift. |
| Tsingtao | Tsingtao Beer | 🚫 | Tested with the highest levels of glyphosate (49.7 ppb). |
| Coors | Coors Light | 🚫 | Tested at 31.1 ppb. |
| Anheuser-Busch | Budweiser | 🚫 | Tested at 27.0 ppb. |
The Bottom Line
1. Choose certified organic beer. It is illegal to spray glyphosate on organic crops, drastically reducing your exposure.
2. Avoid conventional wheat beers. Wheat is frequently sprayed with glyphosate right before harvest.
3. Don't panic about trace amounts. While you should minimize exposure, the levels found in organic drift (like 5.7 ppb) are vastly lower than what you'll find in conventional foods.
FAQ
Is the amount of glyphosate in beer dangerous?
According to the EPA, the levels found in beer (around 20-50 ppb) are well below the legal safety limit. However, many health advocates argue that because glyphosate bioaccumulates, any chronic exposure should be minimized.
Why do organic beers have glyphosate?
Glyphosate is the most widely used agricultural chemical in the world. It spreads through rain, wind drift, and shared water sources, meaning even strict organic farmers can suffer from environmental contamination. Is Organic Produce Actually Pesticide Free
Do craft beers have less glyphosate than mainstream brands?
Not necessarily. A 2023 study published in Toxicology Reports found that conventional craft beers often contained higher levels of toxic pesticides than mainstream brands. The only way to confidently avoid pesticides is to buy certified organic.
