When you consider barley and quinoa, it’s important to understand their distinct agricultural environments and processes. Recognizing how they grow and the steps taken after harvest gives you better insights into these grains.

Growing Conditions

Barley thrives in cooler climates and is quite adaptable to different soil types. It’s commonly grown in temperate regions and has a wide range of varieties, including hulled and pearled barley.

Hulled barley retains the bran and is considered a whole grain, offering a denser nutritional profile.

On the other hand, quinoa prefers well-drained, sandy soil and can even flourish in poor soil conditions where other grains may struggle.

Unlike barley, it’s tolerant of droughts and high elevations, often associated with the Andean climate where it originates. Quinoa’s resilience to varied conditions makes it a remarkable crop.

Harvesting and Processing

After maturing, which takes about 90 days for quinoa and 55-60 days for barley, you’ll find harvesting methods differ.

Barley is harvested similar to other cereal crops; the process includes reaping, threshing, and winnowing. Once harvested, barley is processed into several forms, the most common being pearled barley, where the grain has been polished to remove its bran and germ.

Quinoa’s post-harvest process involves removing the saponins, a natural coating making the seeds bitter and acting as a deterrent to pests.

It’s a crucial step to make the seeds palatable. Quinoa does not come in hulled or pearled forms because its outer layer is not as tough or inedible as the husk of barley grains, and the whole seeds are consumed after the saponins are washed away.
