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!
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.
- See Tip 12 for another method
- In my opinion, this is the quickest and easiest way to seal a Mylar Bag using a traditional type vacuum sealer.
