Last summer marked my first year growing
grains for an edible crop. I came across a variety of Irish oat seeds called
'Sonas,' and thought I'd give it a whirl! Being a Baker by trade, I'm very intrigued to the growing, harvesting
and processing needed to get grains from the soil all the way to flour.
With little research I made a small border 4ft long to grow them, and
away they grew. Very satisfying to watch, as oats are one of the easiest
grains to grow. I had my own notions of homegrown porridge in the year
to come.
It's worth noting here when growing oats for grain in
your backyard, to purchase a 'hulless' variety. Traditional oat grains
have two barriers of covering; the outer husk and a hull coating the
grain. The husk is easily removed from the oats, and with a 'hulless'
variety that is all that is needed. The 'Sonas' oat does happen to have
an inner hull. Which requires cracking and winnowing further, this is
hard to achieve without a grain mill.
I have yet to buy a grain mill, so no porridge for me! I am in
the market for one, and the grains will keep till it arrives. I have
in-the-mean time just recieved a package full of new grains from,
Brown Envelope Seeds, including: Hulless Oats! (the oat saga continues...) I will be devoting 1/3 of my potager to grains this year. Among the oats I'm also experimenting with sweetcorn, flint corn, quinoa, wheat and rye grains.

When growing oats you will find the time to harvest, when pressing the oat grains they are hard and no milky liquid seeps out. To harvest, simply cut the base of the oat stalks and bunch the stems together. The oats will need curing to dry out further, it's best to do this by leaving them up right for a good few weeks, I waited months until I got around to it! Once cured you can begin thrashing and dehusking the grains
The following procedure works for both hulless and hulled varieties of oats. As I mentioned you will have to process the hulled varieties further, to get to your whole oat groats.

Dehusking Oat Grains
- Using a large receptacle, (rubbish bins work well) hit the side of the container forcefully with the oat stems. The oats should seperate from their stalks.
- If you find the grains are being stubborn, as I did, you can pull them off by hand.
- Once removed pour the oats on to baking trays, bake for 1 hour at 80C (180F).
- The husks will become wispy and dry. Let cool and rubb the grains by hand, to help seperate the grains.
- On a windy day go out doors and pour the grains with their husks onto a seperate tray.
- The husks will float away in the breeze leaving you with happy little oat groats or, if you grew the hulled variety like me, oat groats in their hull jackets. (pictured above)
