I have two batches of un-milled grains packaged for a future batch, about 15 pounds bagged. I won't be using these for several months, possibly 6 or more.

Is there any value in storing the bags in the freezer?

What is the best storage method?
 
Treat grains as you would any foodstuff; they are composed of complex organic molecules and can be degraded by many conditions, such as:
oxygen(air), heat, moisture, extremes of pH, light(especially UV), exposure to any critters from fungus to rodents, being finely-divided(milled), radiation(rare), time. Probably others.
I buy mine in amounts which I plan to use soon. They are stored in whatever container they come closest to filling, eg., PET bottles, poly bags, whatever. Then, I flush them with CO2, bought in bulk(eg. 20# cyl.) like this:
WARNING: use CO2 at your own risk; 10% CO2 will cause humans to become unconscious-you have been warned.
Run a poly tube to the bottom of the container(using PET soda bottles allows bottles to collapse a bit-see below), loosely seal the opening, invert the container, slowly flush w/ CO2. This minimizes cavitation.
When done, seal bottle, store in fridge. If sealed, bottle will collapse, not a problem.
 
I store my bulk grains in 5 gallon buckets and everything else in these clear containers meant for food storage that snap shut and have a rubber gasket that makes a nice air tight seal. They come in different sizes that hold anywhere between 3 - 20 lbs.
 
In the freezer is good if totally sealed, otherwise they could absorb moisture. I store my bulk grains in 5 gallon buckets with Gamma lids. Smaller amounts are in lock and lock type storage containers (sealed lid). I have used some grains well over a year old with good results.

Cool and dry. Most important is DRY.
 
I buy a lot of Maillard malts, coming repackaged in ziploc bags. I keep them in a dunage container on the bottom shelf of my wire rack with the lid halves snapped shut. They last a long time high & dry. What light gets to them doesn't seem to be a problem so far. But they are uncrushed as well.
 
Closed plastic bags inside a plastic garbage can, stored in a cool dry place.

I keep my grains in plastic bags, usually in coolers in my garage / brew house attached to the house. This area, for what ever it's worth is kept at 50 degrees during the winter and the only temp control during the summer is when he garage door is closed, (garage / brewery is under the master bedroom) on the north side of the house so the central air being on keeps it pretty cool.
 
I buy used icing buckets from the grocery store bakery for $2 a pop. They seal good enough. I buy some grains in bulk and just dump them in the buckets.
 
I bought a couple 35 gallon plastic barrel with a metal snap ring from the surplus section at macs hardware for something like 15 bucks each. Washed them out, they used to hold naproxin sodium which I think is what aleve is? Keep them in the cellar.

Maltsters store there malt in silos that are vent regulated with blowers.
 
To my understanding, the real enemy of malt is moisture, within reasonable temperature parameters (cooler being better). I store mine in the basement in a Vittles Vault. Works great, never had any sense of staling, highly durable.

Bags of grain are not airtight or even sealed, so while I can't see any harm in purging with CO2, that is certainly not done commercially, as it is with hops.

I use five-gallon buckets with gamma lids for my bulk base malts, as well. They're in my cool, though perhaps not completely arid, basement. I don't flush with CO2 or anything and I recently finished up a sack of MO that if had for about ten months. No issues at all with that grain. All my other grains are stored in Ziploc bags that are in one of those big Rubbermaid-type containers.
 
I use Homer buckets for my base malts and ice cream tubs for my specialty grains. Some I re-vacuum seal in the bags, some I don't. I keep them in my garage where it gets to be 100 degrees in the summer.

I've had some for over a year. They keep fine and taste fresh.

X2, these are great. You can stack them and put them in a corner out of the way. I have four and am thinking of ordering four more.
 
Base malts are in. 5 gallon homer buckets with gamma seal lids. No CO2 flush. Garage temps range from about 50-80F during course of the year. I like how they stack.
 
Homer buckets aren't food-grade, and that may or may not matter to some folks. For me, I bought food-grade buckets from Wal-Mart and put the gamma kids of those.
 
Repurposed old bucket fermenters with gamma lids works great for me. Larger size than homer buckets and food grade.
 
I store base malt in spare pin-lock cornies under CO2 pressure. Specialty malts spend a week in the freezer before storing them in gamma screw top buckets. No weevil issues, ever.

Homer buckets w/ gamma lids. I've heard multiple times the "food grade-ness" often has to do with mold release agent. I give me buckets a good scrub and they're good to go. Haven't died yet.
 
I also use homer buckets.They're hdpe and that's food grade enough for me. Especially when you consider the malt went from an open field to a barely sanitary silo and then to its final home in carelessly mistreated burlap sacks.
 
I used my homer cheapo bucket with my grain mill. But this was after a lot of PBW & Starsan went through it delabeling bottles, sanitizing things, etc. I now use one of the blue Lowe's buckets with the grain mill. Still here, so they're ok.
 
I use Vittle Vaults. Not cheap but they will last a lifetime and keep my grains fresh.
My specialty malts are kept in bags inside the Vittle Vault and my base malts are loose.
 
Another Vittle Vault user here. I have two of the big tubs that will hold 50lb sacks of grain. The small quantity stuff is usually sealed in vacuum bags.
