How long does homemade cold brew last?

Cold brew concentrate keeps for up to 2 weeks in the refrigerator when stored in an airtight container. Ready-to-drink diluted cold brew lasts about 3-5 days. You will notice the flavor peak at days 2-3 and gradually decline after that. Always keep it refrigerated.

Is cold brew less acidic than hot coffee?

Yes. Cold brew is approximately 67% less acidic than hot brewed coffee because the cold water extraction process does not release the same oils and acids that hot water does. This makes it gentler on sensitive stomachs and produces a naturally sweeter, smoother flavor profile.
