Can you freeze cannabutter?
Yes, and freezing is the best way to keep it. Frozen in an airtight container, cannabutter keeps its potency for months, staying best for about three and good for up to six. Freeze it in measured portions and every piece is a dose you already know.
How do you freeze cannabutter in doses?
Pour the strained, still-soft butter into a silicone ice cube tray or a mini muffin tin, one tablespoon per well, using a measuring spoon. Freeze until hard, then pop the cubes into a freezer bag or airtight box.
Because you know the potency per tablespoon, every cube is a known number of milligrams. That turns your freezer into a dosing tool: one cube, one measured amount, no guessing at a block of butter.
Does freezing affect potency?
Very little. THC breaks down with light, heat and air, and a dark, airtight container in the freezer protects against all three. The butter's flavour fades sooner than its potency does, which is why quality is best within about three months.
How do you thaw and use it?
Thaw cubes overnight in the fridge, or drop them straight into a recipe that melts the butter anyway. Avoid microwaving on high, since hot spots can scorch it.
Label the bag before it goes in: what it is, the date and the milligrams per cube, plus the words contains cannabis. A frozen cube looks exactly like regular butter.
Frequently asked questions
How long does cannabutter last in the freezer?
Best within about three months and good for up to six when it is airtight and labelled. In the fridge it lasts about two to three weeks.
Does freezing cannabutter lower its potency?
Hardly at all. Cold, dark, airtight storage protects THC far better than the counter or the fridge door.
Can you refreeze cannabutter?
Best avoided. Freezing in single-tablespoon cubes means you only ever thaw what you need.
