Hi y'all.
Looking at getting into milling my own grains and am now looking at my storage options.
I'm sure I can figure out the containers but as the title suggests I'm wondering about keeping the grains in a shed in good old Victoria with our lovely temp swings.
Just built a 12x7.5m shed with aircell in the roof but nothing in the walls.
If stored in sealed containers will this be ok?.
How and where do you store yours?

Also remember vermin will happily chew thru wood or plastic to get a tasty meal. A mouse only needs a tiny hole.
Hotter the grain the quicker the deterioration and rapidly a write off if it's damp as well.

Damp is my biggest concern. I will be brewing out there and will open all doors but under normal storage conditions I imagine that the shed will get a bit of condensation in it from the temp swings

Build yourself a condenser, transformed my brewday. Big extractor fans are noisy and not that good. Less energy for the boil. Less loss.
Then all you need is a small extractor fan for general air movement. I assume not gas burners indoors?
You could put some damp absorber containers in your grain bins.

Hi mate, got details on your condenser? I brew outside, but under a tin roof and it ends up raining on me after the first half hour in winter.

Hops/specialty grains vac sealed and kept in freezer, dried yeast kept in freezer.
Base malts in opaque airtight poly bins (old screw top fermenters work well) kept in a big old chest freezer, inkbird controlled and also used for crash chilling, lagering etc, surprisingly cheap to run and vermin proof. you can keep at ambient but as cool as possible, it's nice to have everything in one spot but a tin shed in Victoria? Most houses have a "cool" room, usually on the South side, consider keeping your base malts there, it's not like you'll be accessing them every day.
+1 for vermin, in your case a bait station in each corner and another in the middle of the long sides of your shed, you'll be amazed how much bait you'll go through initially, after a month or so things slow down and it's just a case of topping up every 3 months or so.
The big one though is moisture, you can renew those little bags of "do not eat" silica gel that seem to come with everything these days, just pop them in a low oven for an hour or two, I fill a hop sock with them and just chuck it in the grain bin.
I know this all looks like overkill but the first time you lose a bag of malt is heartbreaking, and Murphy dictates it will be a long week-end with multiple brews planned, and no way of getting new stock.
fwiw I'm rural, so maybe the vermin thing isn't as bad where you are, but an ounce of prevention is better than a pound of cure. 😭

I only keep my home dried kveik in the freezer, not sure I've seen any manufacturers recommendations to keep their dried yeast below zero, just below 4 deg Celsius.

Couple of good threads here,

This one has the detail of my one in post seven


I got the parts from a dairy supply company innox.co.nz expect there will be the equivalent in Aus.

But they source all the parts from china.

The most interesting thing about the condenser is how little boil off you get. No problems with DMS it has reduced my water use in the brew, water for condenser I recycle for the garden / washing machine.

Yep, not saying it's best practice it's just what I do, I have a mini freezer for hops/grain/yeast bank, so it's just a convenience thing, otherwise I'd be using the kitchen fridge, and I get enough grief about my liquid yeasts being there, I did discuss getting another fridge dedicated to yeasts but it took 3 days for the mushroom cloud to settle so I shelved that idea, I've never had a problem with it, just take packet out an hour or so before use, then re-hydrate.
