Vacuum sealer bags are great at sealing out oxygen, preventing freezer burn, etc. FoodSaver bags, vacuum sealers and the like are a great way to store hops, grains, spices and more!
Mylar bags block oxygen and are a great way to store hops and other oxygen sensitive materials. As a testament to this, many hop distributors and sellers distribute hops in Mylar type bags. Sometimes those are vacuum sealed and sometimes they are nitrogen flushed.
Mylar bags are not generally expensive, so that’s great! The problem is vacuum sealers that can seal Mylar bags ARE expensive. Sometimes very expensive. That’s not great!
Sealing Mylar Bags Using Traditional FoodSaver-Type Machines
There are some techniques out there that allow you to seal Mylar bags using a standard FoodSaver-type sealer. All the techniques I’ve found make some use of channeled vacuum bags.
The techniques that I’ve run across are cumbersome. I’ve developed two techniques to easily vacuum seal Mylar bags using traditional vacuum sealer type bags. I originally wrote this in 2011. It’s possible someone had used these techniques prior to this post.
#1 The “Nested” Method for Sealing Mylar Bags
- Insert a filled Mylar bag into a standard vacuum sealer bag.
- Vacuum seal the standard vacuum sealer bag.
- The only entry path for oxygen is now the very top of the Mylar bag. That very small opening is protected by the outer bag.
- To access contents, trim a small amount off the outer bag and re-use as many times as possible.
#2 The “Snorkel” Method for Sealing Mylar Bags
- Cut a 1″ strip off the top of a vacuum bag.
- Fill the Mylar bag with hops or whatever you’re going to store.
- Insert the 1″ strip into the filled bag so that the strip sticks out of the Mylar bag.
- Trim the end of this strip so that about 1/2″ is sticking out of the Mylar bag.
- Insert the top of the Mylar bag into the vacuum sealer bag, ensuring that the 1″ strip of vacuum bag is sticking slightly out of the top of the Mylar bag. This acts as a channel.
- Vacuum and Seal.
- Because Mylar bags can be thicker that standard vacuum sealer bags, you may need to double seal the top with your vacuum sealer’s heat strip.
- Trim the excess vacuum bag strip.
- Trick Required: There is a trick here. Notice I didn’t say FoodSaver bag. I, initially, tried this with a FoodSaver bag and it wouldn’t seal correctly. FoodSaver bags are a bit thicker than most others on the market. Look for a thinner style bag to try with this technique.
