Freezing Lactose

I recently bought some lactose to use in a milk stout, but I think I want to delay brewing that until later this year for more of a fall beer.  Think I should freeze the lactose?

That or just vacuum seal it and call it good. It should freeze fine though.

You will be fine with a simple vacuum seal.

Cool - it came sealed albeit not vacuum sealed.  I’ll open it and vac seal.  Thanks guys
