Grand Teton Ancient Grains Organic Einkorn Berries

1. Ingredients 25% of the rating 5 of 5

   One ingredient: organic whole einkorn berries, unmilled, with nothing sifted out or added.

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

   USDA Organic plus the maker’s word that it tests the berries for glyphosate, with no lab or result shown. The outside glyphosate test covered a different Grand Teton flour.

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

   A named family farm and mill in Teton, Idaho. This grain’s growing place, harvest year and pack date are not stated, and contract growers across the northwest also supply grain.

4. Trust 10% of the rating 3 of 5

   No recalls or Prop 65 notices found. Points off for a “Glyphosate Free” badge that is the maker’s own claim, “excellent for sprouting” beside a 40 to 50 percent germination footnote, and discount-code deals with a testing site and a recipe blog.

5. Value 20% of the rating 4 of 5

   $4.48 a pound at 2.5 lb, falling to $3.35 at 15 lb and $3.00 at 48 lb. You also need a mill to make flour.

The rating, 3.5 of 5, is the weighted average of these scores. See how we rank grains & flour and our standard.

1. Organic einkorn berries (whole grain, hulls removed). The product page prints no ingredient list.

• 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 these berries: 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 glyphosate free?

The page says “Certified 100% Organic & Glyphosate Free” and that the maker tests its berries “to certify that they are free of glyphosate”. Only the organic part is a certificate. No lab or result is 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 these berries. That article lists a “MAMAVATION” discount code for Grand Teton products, so the brand and the tester have a commercial tie.

Can I sprout them?

Poorly. The page calls the berries excellent for sprouting, then notes that hull removal cuts germination to 40 to 50 percent, which the maker says it tested. The FAQ (opens in a new tab) gives 40 to 60 percent and says the seedlings lack vigor, and that the berries are not recommended for seed.

Do the berries arrive with weevils or debris?

The FAQ says all grain can carry weevil eggs, that Grand Teton will not ship grain with weevils, and that freezing the bag for a few days kills any eggs. Home millers on Reddit describe its grain as clean, for example “No debris, bug bits, or rocks” (opens in a new tab). Those comments cover its grains in general, not einkorn specifically.

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 product. Cadmium concentrates in the bran, so whole grain carries slightly more than white flour (see our cadmium article).

Is einkorn safe if I avoid gluten?

Not with celiac disease. The FAQ says einkorn is not gluten-free but that many people with gluten sensitivities eat it without problems, and advises talking to a health care professional first. A 2022 review (opens in a new tab) found ancient wheats contain more protein and gluten, and more celiac-active epitopes, than bread wheat.

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 in its handling scope (record read 22 Oct 2026).
• It is a whole grain by form: the page describes the berries as whole grains, unmilled, with the hull removed, so nothing is sifted out.
• Prices run from $11.21 for 2.5 lb ($4.48 a pound) through $26.91 for 7.5 lb ($3.59), $50.23 for 15 lb ($3.35) and $143.95 for 48 lb ($3.00), read 23 Oct 2026.
• The maker packs in paper bags “to eliminate contact with plastic”, and its FAQ gives a shelf life: up to 2 years in paper bags.

• The glyphosate claim is the maker’s own. It says it tests the berries and certifies them glyphosate free, 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 product.
• The page does not say where this grain was grown, or give a harvest year or pack date. The FAQ says the farm also contracts growers across northwestern North America.
• The hull has been removed, which the maker says drops germination to 40 to 50 percent, yet the page still calls the berries excellent for sprouting. Use them for cooking or milling, not sprouting.
• At 2.5 lb the berries cost more per pound than the maker’s ready-milled whole wheat flour ($3.97 at 5 lb). They only undercut it at about 15 lb ($3.35 a pound) and above, and you also need a mill.
• Einkorn is wheat. It contains gluten and is not safe with celiac disease. The FAQ only advises talking to a health professional first, and says many people with gluten sensitivity tolerate it.
