Grand Teton Ancient Grains Organic Einkorn Whole Wheat Flour

1. Ingredients 25% of the rating 4 of 5

   One ingredient and, per its FAQ, nothing added. Held at 4 because the page both says 100% whole grain and describes sifting out most of the bran.

2. Independent testing 25% of the rating 2 of 5

   USDA Organic plus the maker’s own word that it tests for glyphosate and mold, with no lab or results shown. The outside glyphosate test covered its all-purpose flour, not this one.

3. Sourcing & freshness 20% of the rating 3 of 5

   Milled at its own mill in Teton, Idaho, a few times a week and shipped fresh. Grain origin is given only as Idaho plus contract growers in the northwest, and no milled-on date is on the page.

4. Trust 10% of the rating 2 of 5

   No recalls or Prop 65 notices found. Points off for a page that contradicts itself on whole grain, a “Glyphosate Free” badge that is the maker’s own claim, unsourced “Easy to Digest” wording, and discount-code deals with a testing site and a recipe blog.

5. Value 20% of the rating 5 of 5

   $3.97 a pound at 5 lb and $3.32 at 40 lb, the lowest price per pound of the flours here.

The rating, 3.3 of 5, is the weighted average of these scores. See how we rank grains & flour and our standard.

1. Organic whole-grain einkorn flour. The product page prints no ingredient list; the FAQ says nothing is added or removed from the whole-grain flour, and the page says it has no additives.

• Paid certification USDA Organic, certified by the Idaho State Department of Agriculture October 2026

  Audits the farm’s and mill’s practices and records. Certifiers must also residue-test samples from at least 5 percent of the operations they certify each year (7 CFR 205.670), so no lot is tested by default. Open ↗ (opens in a new tab)

• Independent Mamavation (consumer site; earns Amazon affiliate income and lists a discount code for Grand Teton products) June 2026

  Glyphosate in Grand Teton’s all-purpose einkorn flour, not this whole-grain flour: not detected at a 10 ppb limit, by an EPA-certified lab using LC-MS/MS. Ten organic all-purpose flours were tested. Readers mostly donated the samples, and donations from Environmental Health News and readers paid for the testing. Heavy metals and mold toxins were not tested. Open ↗ (opens in a new tab)

Is it really whole grain?

Probably, but the page contradicts itself. Its headline says “Whole Grain, Freshly Stone Milled”, and the maker’s FAQ (opens in a new tab) says its whole grain flour is “just the berries ground into flour with nothing added or removed” and that the all-purpose flour is the one that is sifted. The all-purpose page adds that a 100% whole-grain flour is sold separately. But a paragraph lower on this page says the flour is “sifted to remove most of the bran”. The nutrition panel on einkorn.com (opens in a new tab) shows 12 g of fiber in 136 g (about 8.8 g per 100 g). That sits between Jovial’s sifted einkorn label (about 6.7 g per 100 g) and its whole wheat label (about 12.5 g per 100 g), so it does not settle the question, and it does not say which of the two flours it describes. We have asked the maker which statement is right.

Is it glyphosate free?

The page says “Certified 100% Organic & Glyphosate Free”. Only the organic part is a certificate. The FAQ says the maker tests its grains for glyphosate, yeast and mold, with no lab and no results shown, and Grand Teton is not on The Detox Project’s list (opens in a new tab). Mamavation’s 2026 test (opens in a new tab) found no glyphosate in Grand Teton’s all-purpose einkorn flour, not this one. That article lists a “MAMAVATION” discount code for Grand Teton products, so the brand and the tester have a commercial tie.

Has it been tested for heavy metals or mold toxins?

No results are published. The maker says it tests for yeast and mold and names no lab. We found no independent heavy metal test of any Grand Teton flour. Lead Safe Mama (opens in a new tab) has tested Jovial’s einkorn but not this brand. Cadmium concentrates in the bran, so whole-grain flour carries slightly more than white flour (see our cadmium article).

Is einkorn gluten “good”, and is the flour easy to digest?

The page title says “Easy to Digest” and its text calls einkorn gluten a “good gluten”, citing customers, not research. The FAQ says einkorn is not gluten-free and advises talking to a health care professional before trying it with celiac disease. A 2022 review (opens in a new tab) found ancient wheats contain more protein and gluten, and more celiac-active epitopes, than bread wheat. Einkorn is not safe with celiac disease.

Where is the grain grown, and how fresh is the flour?

The FAQ says the farm is in Teton, Idaho and surrounding areas and that it also contracts farmers in the northwest of North America. einkorn.com says this flour is milled from Idaho-grown grain. The page says each order is milled on the next milling day and shipped fresh. It shows no milled-on date, although the all-purpose flour page says its bags print one.

Who is paid to promote it?

Grand Teton works with promoters through discount codes. The recipe blog Glue & Glitter (opens in a new tab) says it is working with the owners and gives readers 15 percent off a first order with its own code, and it notes that its posts may contain affiliate links. Mamavation (opens in a new tab), which tested Grand Teton’s all-purpose einkorn flour, lists a code for 10 percent off. We could not see the terms of either deal.

• The USDA Organic Integrity Database lists Ancient Grains, LLC dba Grand Teton Ancient Grains (NOP ID 2170041852) as certified by the Idaho State Department of Agriculture since 2013, with Einkorn Flour in its handling scope (record read 22 Oct 2026).
• It is the lowest price per pound of the flours we list: $19.87 for 5 lb ($3.97 a pound), $37.08 for 10 lb ($3.71) and $132.95 for 40 lb ($3.32), read 23 Oct 2026.
• The maker says each order is milled on its stone mill on the next milling day, a few times a week, in a mill used only for einkorn, and shipped by 2-day service. The flour comes in paper bags, not plastic.
• Its FAQ says nothing is added to either of its einkorn flours: no bromate, no folic acid and no added vitamins.

• The page contradicts itself on whole grain. The headline and the FAQ say whole grain with nothing removed, but a paragraph lower down says the flour is “sifted to remove most of the bran”. That paragraph looks like text shared with the all-purpose flour, whose page says the whole-grain flour is sold separately. We have asked the maker which is right.
• The glyphosate claim is the maker’s own. It says it tests its grains for glyphosate, yeast and mold but names no lab and posts no results, and Grand Teton is not on The Detox Project’s list. An outside lab found no glyphosate in its all-purpose einkorn flour, which is a different flour.
• No mill date is shown on this page, although the all-purpose flour page says its bags print one. The grain’s origin is only given by region.
• Einkorn is wheat. It contains gluten and is not safe with celiac disease. The page title says “Easy to Digest” and the text calls einkorn gluten a “good gluten”, with no source. We do not repeat those claims.
