Okay real talk. After freeze-drying milk from so many mums, I can almost tell before I even open the cooler bag.
The stashes that come in frozen flat, air pushed out? Neat, stackable, clean. The ones with air trapped inside? You can already see the little ice crystals forming along the top. That’s freezer burn starting.
Same milk. Same freezer. The only difference is a five-second habit before the bag goes in.
So if you’re building a stash, this is the one worth keeping:
Push the air out. Seal it. Freeze it flat.
Flat bags stack like files, so you fit way more into the same freezer. They thaw more evenly. And honestly they travel better too when it’s time to send them over to us.
