Freezing is okay and helps for storage of big bags, but freezing and taking them out and putting them back in every day isn't good because of the condensation.
I don’t do that. I only thaw and grind enough for about a month’s consumption at a time. I got ~6 pounds of coffee for Christmas and only have a cup a day usually.
I was just providing my process because it seems, unintentionally, well designed to avoid condensation.
