Equipment

  • airtight container
  • marker or pen
  • freezer bags
  • Ice Cube Tray

Instructions

In the carton

  • You can simply toss the whole, unopened carton into the freezer.
  • Notes:
    1) for extra protection, toss it into a freezer bag first.
    2) Liquids expand when frozen, this may tear or bulge the carton.
    3) Store-bought cartons don't provide as much protection as freezer safe containers or freezer bags, so it may not last as long this way without quality degredation.

In a freezer bag or airtight container

  • Portion it into the amounts you will need when defrosted.
  • Pour your portions into individual airtight containers or freezer bags.
  • Seal your packages up:
    containers: place the lid on top. Try to use containers that will only have 1 - 2 inches of space between the oat milk and the lid.
    freezer bags: carefully push any air from the bag, then zip it shut.
  • Take a market and write the date on the outside of the container or bag.
  • Lay it flat in the freezer.

In an ice cube tray

  • Pour your oat milk into each hole in the ice cube tray. Leave a little space at the top of each for it to expand as it freezes.
  • Pop the tray into the freezer for a few hours until the oat milk is frozen solid.
  • Remove from the freezer and pop your frozen cubes out of the tray.
  • Toss the frozen cubes into an airtight container or freezer bag.
  • Seal your package:
    container: press the lid down on top of the container.
    bag: press the air out of the bag and zip it closed.
  • Jot the date onto the package and toss it into the freezer.

Notes

Portion it right: package and freeze it in the portion sizes you will need when you defrost it.  This way you can just defrost the amounts you need at a time.
Do it fresh: the fresher it is when you freeze it, the better.  This will help it maintain maximum taste and quality.
Plan it's use: defrosted oat milk is a little grainier than fresh oat milk even after whisking it together.  So you may not want to use it for plain drinking. Although, I find it to be fine, my husband, for instance does not like it.
