I generally get one or two weeks worth of beans so do not freeze although I have before. If you have more than a months supply seal some and freeze them, will prolong the freshness. If you divide your beans into single brew amounts you can throw them directly through the grinder but if you freeze larger amounts take them out and allow the temp to stabilize before opening to prevent condensation buildup and do not re freeze. Ideally you wouldn’t freeze, rather buy less beans at a time, but does help if you end up with too much.
