You brew a big batch of cold brew, you drink 1,2 or 3 glasses a day and after a couple of days, you still have some cold brew left. So now you are asking yourself “Does cold brew coffee go bad? And after how long time?”.
That is what I will try to answer today!
But first, make sure to join the DripBeans Facebook-group. This the perfect place to ask any future questions about cold brew and get answers from hundreds of cold brew lovers.
Can Cold Brew Go Bad?
Yes, it can. But, first, we will have to be clear with what we mean by “go bad”.
Do you mean that the coffee starts to taste bad? Or, do you mean that it is harmful to drink it?
Both of these options can, of course, be true, but there is a big difference in how long time it takes for the coffee to reach the different stages.
The coffee is of course also affected by how you store it. Do you store it in the fridge? With or without a lid, is there other food nearby? Etc. Maybe most important, have you removed the ground coffee from the cold brew? (you really should!).
How Long Before Cold Brew Goes Bad?
It varies. It all depends on temperature, how you store it and so on.
If you are worried about the taste and not if it is harmful, I would suggest just tasting it. If it starts to taste bad very fast, maybe you should get a cheap airtight jug that can save your all valuable coffee from going bad.
If you are more worried about the coffee getting so bad that it would be harmful to drink it, I think you should stay calm. Cold brew will keep for at least one week at least. In most cases even longer than 2 weeks. But, then the taste won’t be the same and I think that is the bigger problem.
After all, you drink cold brew because you enjoy it. Not because it is not harmful…
Solution
The solution is easy, brew no more cold brew than you would drink in 2-3 days. If you for some reason skip your cold brew for 1,2 or even 3 days, you would still finish the whole batch in under a week.
After all, cold brew is pretty easy to do. If you don’t know how to make it, check out our cold brew video guide.
