So there you have it, coffee comrade. Cold brew lasts one to two weeks in the fridge, with its golden era right around days three through five. Store it right, trust your nose, and never let a jar of liquid gold meet an untimely end. You’ve got this.
And hey, if you finish a batch before it goes bad, that’s not a problem—that’s a victory lap. Pour yourself one last perfect glass, toast to your own coffee prowess, and smile. Because life is short, but homemade cold brew is a beautiful, caffeinated adventure—and now you know exactly how long it’ll last. Go forth and steep, my friend. The fridge is your oyster.
