How long will crushed grain keep?

[scrambledegg81]

Noobish move on my part...got my AG equipment together in a rush and completely forgot that I needed to get my keggle cut & cleaned. The LHBS already crushed the grains (nice folk that they are), and they're currently in a heavy-duty paper grain bag that's taped closed.

Seeing as I may not be able to get the keggle thing figured out for another week or so, how long should most grain stay fresh in 65-70, low humidity?

It should be fine for a couple of weeks. If you put it in a plastic bag, and keep it cooler, it'll last longer.

Freeze it, freezer bag + Tupperware.

Before my wife gifted me with a barley crusher for Christmas (bless her!) I kept my crushed grain in the freezer portion of my keggerator.

 

[Mavtech]

I kept crushed grain in one of the orange paint buckets with the sealed lids from Home Depot for 2 weeks. It was perfectly fine.

 

[defenestrate]

+3 on a few weeks. i order my batches 3 or 4 at a time and some sit for a month. FWIW, country malt recommends using its pre-crushed within 3 months.

I had grain from a PM oatmeal stout in an air-sealed bag, in a Tupperware container, in the freezer that kept fine for 2 months.

few weeks if sealed up

Sorry to re-hash this lads, but I'm in a pickle: I'm typing this with one hand seeing as the other has 2 broken knuckles (got into it with a certain family member yesterday...don't ask).

Long story long, I'm not brewing for at least a month or 2. These grains have been sitting in the freezer for a week now, and I'm just starting to think they're a lost cause if I can't get them into a brew soon. Any thoughts on whether or not to cut my losses or should they keep for that long (again, milled about a week ago).

Put it in a zip lock and remove as much of the air from it as you can. Store the grain in your freezer until you brew day, you should be fine for a month.
You can also pop a few pieces into you mouth and taste if they have gone stale. It's kinda like how you can tell the difference between fresh & stale potato chips.

 

[bradjoiner]

you are fine brew the beer whenever you get the chance

 

[Laughing_Gnome_Invisible]

You are good to go..........However, it's always a good move to persuade the missus that she needs a foodsaver, they are very handy.

 

[Arkador]

Foodsavers are great for saving money on meat, hops, and crushed grain.

I resuse bags for crushed grain all the time.

I kept a crushed brown porter grain bill in a plastic garbage bag sealed with a cable tie in my basement for a month. Everyone said it was the best porter I ever brewed....

Either my other attempts sucked or the grain was no worse for the wear.

Based on my experience, I feel comfortable within 3 months. Just using plastic bags and a cool, dry place, I've used pre-crushed base grains up to 6 months out. I wouldn't recommend it but it turned out ok. There was a certain "meh" to the beer that I blame on how stale the grain was. I once used some pre-crushed chocolate malt I forgot I had a year after the crush. I looked it over well for any sort of mold or critters and didn't find any. That beer turned out great.

Keeping crushed base grain for an extended period is obviously a bad thing.

However, mellowing out a strong taste profile grain like chocolate malt might be considered a process in a particular recipe of your own making. An aged and weaker tasting chocolate grain might make an interesting speciality grain IMO.

What about uncrushed. I was thnking of picking up a 55lb bag of base grain. Wondering how fast I would have to use it.

 

[Grinder12000]

I used grain at the 9 month range - friend says it's ok - I say it's skanky!

[Brett3rThanU]

I used crushed grains that were sealed in a bag after 6 weeks and everything was fine. I did the taste and smell test.

 

[mb2696]

i buy all my grain in bulk and crushed. some of it is a couple months old by the time i use it. i keep it in sealed bags and haven't noticed any staling or off flavors

 

[petep1980]

Throw it in the freezer you're set for a while.

I know this is an old thread, but for prosperity, I'll mention that I brewed 4 10gal batches of beer in my new bewery, forgetting that the grain was out of date by 2 years.

The beer had little head, and just tasted totally one dimensional. Like a glass of water sugar with a stale twist. Brews a year ago were also not up to my expectations.

Resurrection because I was seeking verification for what I've been doing for some time now.

Northernbrewer has flat rate shipping so I order crushed grain bills, 4-6 batches at a time. Sometimes I'll brew that in a week, other times over several months.

Just cracked open a vanilla porter I made in August 2011 with grain crushed in December 2010. Bought enough grain to make 3 batches, the August was the last of it. Beer turned out EXCELLENT. It was the first time I've truly made an effort to properly age a heavy brew and it was totally worthwhile. The other two batches at 4 and 6 months aged were nowhere near as great as this.

Properly stored, away from oxidizers (sealed container, controlled environment) I suspect crushed grains will be fine 3 months out. At least in my experience, I have not noticed a discernible difference between grain brewed immediately after crushing and grain that's been stored for a couple months. And like I stated above, 8 months after crushing I brewed what turned out to be the best porter I've ever made.

Also resurrection: I accidentally left that entire bag of grain in my freezer in San Diego when I moved to central CA.

 

[GarageDweller]

lol. how's the broken knuckles?

Go back for it. It's not too late.

 

[scrambledegg81]

Gah...forgot about that. Knucks are fine, but the tarsal joint in my right pinky finger healed weird and I now have a funky looking bump in my palm over that joint.

I started reading this and was thinking "surely nobody loves brewing THAT much"?!!!

I was about to start a new thread, curious about keeping quality. Our local Home Brew Supply Shop would sell me a 50# bag of 2 row pale malt for $51 which makes it pretty cheap. I was not sure if would have been a good idea to have them crush it first in their professional crusher or rather I use the "grist" mill I have at home. It's one of those hand crank affairs that you put the grain in the top and crank and depending on how right the two metal plates are from each other determines the size of grind.

I could keep it in a sealed 6 gallon twist lid bucket that has a gasket on it and seals air tight, and in the Quonset over the winter. Summer might be a different story.

As an aside, Bell's Brewery, just down the road 40 miles from me, has some newer equipment which allows them to crush 2,000 pounds of malt in 4 minutes, which used to take them an hour to do before.
