How rye is grown
Rye survives snow cover that kills winter wheat. Its leaves make their own antifreeze proteins.

The short version
Farmers sow this cereal in autumn on land too cold or poor for most other grains. It sprouts, sits through the winter, sometimes under snow, and takes off in spring. A combine harvester cuts and threshes it just like wheat. Germany leads world output, and the grain goes into bread, beer, whiskey and animal feed.

Sow in autumn
Winter varieties, the most popular kind, go into the ground in autumn and start to grow before the cold arrives. Rye accepts much poorer soil than most cereal grains need.
-
Wait out the winter
The plants keep growing on warmer days when sunlight lifts them above freezing, even with snow around. Antifreeze proteins in the leaves help them cope. Stalks later reach 1 to 2 meters.
-
Cut and thresh together
A combine harvester cuts the plants, threshes and winnows the grain, and drops the straw back on the field. The straw can be baled later or left to feed the soil.

Clean out the ergot
This crop is highly susceptible to ergot, a toxic fungus. Modern grain cleaning and milling have nearly eliminated the disease it causes, though only as long as the checks are kept up.
-
Store at the elevator
Grain goes to local silos or regional elevators, where lots are combined for storage and shipment. Relatively little of it crosses borders.
Worth repeating
- Among cereals, only wheat and rye have the qualities needed to make a loaf of bread.
- This hardy grain grows as far north as the Arctic Circle.
- Europe's rye likely arrived as a minor admixture in wheat crops, and was only later farmed in its own right.
Where it comes from
- Germany25% of world output
2023 world rye production of 12.7 million tonnes, as quoted on Wikipedia. Poland and Russia are the next largest producers.
