Cold Brew Coffee

Hey guys! I recently made cold brew coffee. I used 250ml cold water, 12g of dark roasted coffee beans(woody dark chocolate profile) and brewed for almost 24 hours. Afterwards I strained it twice with a strainer and cheesecloth and tasted it afterwards. It tasted great(the usual - mildly sweet and a hint of dark chocolate). I bottled it and stored in the refrigerator overnight. The following day, I tasted it again and it was bitter. What could've happened? Usually cold brew can be stored for a week in the ref, but I don't understand why it came out bitter when it should be mildly sweet. Any insights would be great! Thanks!

My experience has been that bitterness is often caused by over-extraction, which itself is often caused by using too fine a grind for your preferred brewing method. I'd suggest grinding a little coarser on your next attempt. In case you're curious, I usually grind for french press when making cold brew coffee.

The chilled coffee becomes slightly bitter as it sits in the refrigerator chilling, even if it's only for a few hours. It happens all the time. If your don't add milk to your cold brew, it would be more noticeable. I know that a lot of people don't add milk and sweeteners to their hot coffee, but they do add them when they drink iced coffee.
Also it might be beans. For instance, I once bought Tiny Footprint and the batch tasted bitter when it was cold.
