What Are Ancient Grains?

The term "ancient grains" refers to cereals and pseudo-cereals that have been cultivated for thousands of years with minimal selective breeding. Unlike modern wheat — which was extensively hybridized throughout the 20th century to maximize yield and disease resistance — ancient grains retain their original genetic makeup, flavor complexity, and nutritional density.

Nutritionists and food scientists increasingly recommend ancient grains as part of a balanced diet because many varieties are higher in protein, fiber, and micronutrients (zinc, iron, magnesium) compared to refined modern wheat. They also tend to have a lower glycemic index, meaning they cause slower blood-sugar spikes after eating.

For bakers and cooks, ancient grains present a practical challenge: each variety has a different density, water absorption, and cook time. A cup of farro weighs 190 grams, while a cup of bulgur weighs only 145 grams — a 31% difference that matters when following weight-based recipes.

Grain-by-Grain Guide

Farro

Farro is an umbrella term for three wheat varieties: emmer (most common in Italy), einkorn, and spelt. When sold in the US, "farro" almost always means emmer farro (Triticum dicoccum). It has a nutty, slightly chewy texture that holds up well in salads, soups, and grain bowls. One cup dry weighs 190g and yields about 2.5 cups cooked. Cook semi-pearled farro in salted water for 25–30 minutes; whole farro can take up to 40 minutes. It is not gluten-free.

Kamut (Khorasan Wheat)

Kamut is a trademarked name for khorasan wheat (Triticum turgidum ssp. khorasan), an ancient relative of durum wheat with large, elongated kernels. It has a rich, buttery flavor and is prized by those who find modern wheat hard to tolerate — though it still contains gluten. With 200g per cup, kamut is the densest grain in this comparison. It takes the longest to cook (70–90 minutes), so pre-soaking overnight significantly reduces cooking time.

Freekeh

Freekeh is green durum wheat that is harvested early and roasted over fire — a technique from ancient Levantine cuisine still practiced today. The roasting gives freekeh its signature smoky, grassy flavor. At 175g per cup and only 20–25 minutes cook time, it is one of the fastest-cooking whole grain options. It also boasts the highest fiber content in this group at 16g per 100g, plus a respectable 13g of protein.

Einkorn

Einkorn (Triticum monococcum) is the oldest cultivated wheat species, domesticated around 10,000 years ago in the Fertile Crescent. It has a higher proportion of carotenoids (giving it a golden yellow color) and the highest protein of these grains at 18g per 100g. The gluten structure in einkorn is weaker and more extensible than modern wheat, which is why einkorn baked goods are denser. At 195g per cup, it weighs slightly more than standard wheat berries.

Spelt Berries

Spelt (Triticum spelta) was a staple crop in Europe from the Bronze Age through the Middle Ages. Spelt berries (the whole unprocessed kernel) weigh 188g per cup and take 60–90 minutes to cook. Spelt has a mild, nutty flavor and is relatively high in fiber (11g per 100g). Note that spelt flour is different — it is lighter and works well in baked goods as a partial substitute for all-purpose flour.

Wheat Berries

Wheat berries are the whole kernel of modern wheat (Triticum aestivum) — the germ, bran, and endosperm intact before any milling. They are the foundation of all wheat products and weigh 195g per cup. Like spelt berries, they take 60–90 minutes to fully cook. Wheat berries have an excellent nutritional profile with 13g protein and 12g fiber per 100g, and a pleasantly chewy texture that works well in pilafs and stuffed vegetables.

Oat Groats

Oat groats are the whole oat kernel with the inedible hull removed — the most minimally processed form of oats. They weigh 175g per cup and take 45–60 minutes to cook, yielding 3 cups cooked per 1 cup dry. Oat groats are the base from which steel-cut oats (chopped), rolled oats (steamed and flattened), and quick oats are derived. They have 13g protein and 11g fiber per 100g, plus uniquely high levels of beta-glucan fiber linked to cholesterol reduction.

Bulgur

Bulgur is the lightest grain in this comparison at 145g per cup — and also the fastest to prepare at just 12–15 minutes. It is made from whole wheat that has been parboiled, dried, and cracked. The pre-cooking during processing means bulgur only needs to rehydrate, not fully cook. It has exceptional fiber (18g per 100g) because of its intact bran. Bulgur is the base of tabbouleh and many Levantine dishes.

Quinoa

Quinoa (Chenopodium quinoa) is technically a seed from the Andes, not a true cereal grain — but it is cooked and eaten like one. Quinoa weighs 170g per cup dry and cooks in just 15–20 minutes, yielding 3 cups cooked. Its standout trait is being a complete protein (14g per 100g), containing all nine essential amino acids. It is also naturally gluten-free, making it the best ancient grain option for celiac disease or gluten intolerance.

How to Substitute Ancient Grains in Recipes

When substituting one grain for another in a recipe, you need to account for three factors:

1. Dry weight density: Use our comparison tool above. If a recipe calls for 1 cup (190g) of farro but you want to use quinoa (170g/cup), you need approximately 1.12 cups of quinoa to match the same dry weight.
2. Water ratio: Different grains absorb different amounts of water. Check the water ratio column in the comparison and adjust accordingly.
3. Cook time: Bulgur takes 12 minutes while kamut takes 90. Plan your cooking time — or pre-cook grains in bulk and refrigerate for up to 5 days.

Storage Tips

All whole grains should be stored in airtight containers in a cool, dark place. Because they retain the bran and germ (which contain oils), whole grains can turn rancid. For long-term storage beyond 6 months, store in the refrigerator or freezer. Properly stored, most ancient grains last 6–12 months at room temperature and 2+ years frozen.
