Hands On Review: Gamma Seal Lids for Homebrew Grain Storage

gamma seal lids review

Buckets are… Good for Grain Storage

Buckets are cheap and efficient containers for storing bulk homebrewing malts.  They are generally sturdy and cost effective.  Since they stack, they are also space efficient.  Search Amazon for “food safe buckets”

How Much Grain Can You Store in a 5 Gallon Bucket?

My general rule of thumb for unmilled malt storage is 5 lbs per gallon.  That means a 5 gallon bucket would hold about 25 lbs.  Two x buckets would hold a full 50 lb bag of malt.  That’s a rough estimate.  Actual storage capacities will vary.

The Problem… Lids

I’ll group standard bucket lids into two categories.

  • First… relatively easy to install and remove and…. questionable on air-tightness.  No o-rings or gaskets.  They go on fairly easy and come off relatively easy.  Sometimes too easily, I’ve had this style pop off on their own.
  • Second… sturdy, airtight lids… that require the power of Thor to remove.  These are gasketed and seal well but are tough to remove.  They’re so hard to remove, they make tools to do it.  If you’re stuck with these lids, those are worth a look.  Search Amazon for “bucket lid opener” to see what’s out there.

The Fix… Gamma Seal Lids!

High quality, gasketed lids do exist for 5 gallon buckets.  The problem with these lids is… they are usually difficult to remove, sometimes very difficult.  The revolutionary thing about Gamma Seal lids is that the ring stays installed on the bucket.  That ring is used in conjunction with an easy to remove spin off lid that features airtight seals.  Airtight + Easy to Use = Whammo!

Outfitting your buckets with Gamma Seal Lids allow you to convert relatively cheap buckets into easy to use, airtight grain storage containers.

These are a great option for grain storage.  I’ve used (many) of these for years with great success.  For kits, I’ll generally store 1 kit per bucket (less the parts that need refrigerated) and leave the contents in any bags they came in.  For bulk grains, I’ll generally remove those from any packaging and put them right in Gamma Seal Lid-outfitted buckets.

For labeling, I affix GrogTag’s Keg and Carboy Labels on each bucket.  Those are write on/wipe off friendly, so they keep the bucket looking nice.  You could also just write on the bucket directly, the marker will probably stain the outside of the bucket over time, but no huge deal.

After years of use, I can heartily recommend these as upgrades to your grain storage buckets.

    I use one of these on my primary fermenter. I’ve done about 4 brews with it. I drilled a hole in the exact middle of the lid for the airlock and it works great. Leaves just enough clearance for the handle and my knuckles to clear it while transporting it.

    The ring around the top CAN be a great place for bacteria to grow so after removing the beer I spray hot water along the bottom of the ring with the vegetable sprayer on my sink. Then I fill the bucket all the way to the top with super hot water and PBW, put the lid on and let it sit overnight. The next day I drain thoroughly rinse, set upside down to dry and then put it away with the lid on tight. So far, I have never had an infection. Even on big beers when the krausen reached the lid, they turned out fine.

    Has anyone tried these lids on a fermenter yet? My current lids are getting old and seem to leak a little.

    Could anyone comment on using these as a primary bucket lid by drilling a grommet hole for an airlock? Do they seal tight enough for that? Seems like twisting it off would be more ideal than popping off the regular lids which could shake up trub? Make sense?

      I believe that they are tight enough for this to work. My concern would be cleaning and sanitizing. Awful lot of space in nooks and crannies that would be hard to clean and sanitize. If you were planning to completely remove the outer ring every time, I think it would be fine.
