How Long Does Cold Brew Coffee Last?
Avid coffee drinkers attest to the fact that cold brew coffee usually only lasts one to two weeks in the refrigerator. Once your coffee has been stored for a week, it will start to lose its caffeine content and you might notice a slight variance in its flavor. In two weeks, cold brew coffee might begin to smell, this is a sure sign that the coffee has gone bad.
If you dilute the coffee concentrate with cream prior to storing in the fridge, you can expect to have a much shorter shelf life. Granted, you can likely brew the coffee using older grounds, and it would still last 7-14 days in the fridge, but it would not be nearly as delicious right off the bat as the fresh-ground batch. While you will get more than 2 weeks of enjoyment out of your cold brew when it is stored in the refrigerator, be aware that coffee flavors start to deteriorate after the first week, and this is inevitable. A lot of this comes down to how much preparation goes into the beginning, if you take your time making sure that everything is sterilized and that the Cold Brew Coffee is filtering out after being brewed through the paper filter, it is still going to taste absolutely amazing 2 weeks later.
| Shelf Life | |
| Older coffee grounds | Will last up to 7-14 days in the fridge. |
| Dilute Coffee | It will last for only 2-3 days in the fridge. |
You also need to make sure that your grounds are not super coarse; otherwise, your coffee will have weaker, non-coffee-like flavors. Experts recommend using coarser grinding as this makes it easier to filter. If you can avoid standard pre-crushed coffees that are sold in markets, then buying the whole beans and grinding it yourself is recommended.

If you want to get best results, using the correct kind of beans and following proper instructions is recommended for making your own coffee at home. You can find various recipes to guide you to make cold brewed coffee at home, and the process is pretty easy to do unless you are ok with steeping the coffee beans in water for up to 24 hours.
While you might find a few recipes that recommend steeping in cold water on your kitchen counter, it is always best to brew in your fridge. Another benefit is that, unlike hot coffee, cold brewed coffees can last a long time in the refrigerator and not taste compromised. Do note that the flavor of the cold brew does begin to wane after the first week, but it is still better than any soda, fruit juice, or poured over ice coffee that you may find on the market.
Cold brew is different than iced coffee, which has been heated up especially to extract those extra layers of flavour and other naturally occurring coffee compounds, which are not extracted as much, if at all, in cold brew (see ourScience Corner piece below for more about the extraction). The issue with the iced coffees that gave rise to the Cold Brew Obsession is that, even though cafes make an extra effort to chill their hot brewed coffees to prevent you from getting a sour cup of coffee, a hot-brewed cold coffee is often acidier than hot, unchilled coffee, the resulting acidity is often higher than hot, unchilled coffee. Generally, the process of cooling encourages oxidation, making the chilled hot coffee more acidic than a warm, chilled coffee.
The quality of hot coffee begins to deteriorate within 30 minutes of the water touching the grounds of coffee beans. The flavors in a hot coffee usually begin to deteriorate in the first half-hour of the roasting process, the same is true of a regular coffee that is cold. Keeping your cold brewed coffee sitting on the counter is not going to cut it, and as I wrote in my earlier post about leaving your coffee untouched, hot coffee is best within 30 minutes, fine within about 24 hours, and then rapidly declines from there.
If you add water to your cold brewed concentrate before storage, or keep a cold brewed from the coffee shop in your refrigerator, it is best consumed within 3-4 days. Unrefrigerated- If you are steeping your Brew at your counter, it will keep fresh for 14-18 hours. Coffee experts recommend that chilling your cold brew is the best way to keep it for at least one or two weeks (for an undiluted cold brew), while sitting at room temperature, the flavors start sour in just 2 hours, and in another couple of hours, mold starts forming.

Brewn espressos can also be stored for several hours at room temperature, or kept refrigerated in sealed containers for several days, however, the taste will diminish. If you keep your cold coffee in the refrigerator, you can still slurp it up over the next few days, but chances are, you will not want to. The flavor may have gone, and it is still totally safe to drink, but life is too short for a subpar coffee, so if the flavor has gone, throw it out and brew some fresh.
Make sure you sniff the coffee you are making and check for any signs of spoilage before you drink because the milk will go bad. Leaving coffee out in the cold does not make an enjoyable cup, even in the winter when your home is fairly cold all around. With over-extracting your coffee, you are left with weaker coffee, and your coffee does not keep as fresh as you would like.
While cold-brewed ready-to-drink uses just the right amount of coffee right at the start, giving you the strength and flavour you want (so you do not have to dilution), concentrates are made with more or less coffee grounds, and need to be diluted with cold water once you have ground it, says Travis Beckett. The dilution process helps reduce bitterness, while also yielding twice as much coffee as you would get if making a coffee hot. If you are looking to brew small batches, simply reduce the coffee to water ratio, keeping it similar.
Because although store-bought cold brew is probably treated with more preservatives and additives to help it last longer, you have no idea how long it is been in the bottle yet, and may have spent months in the warehouse or shipping container before ever reaching the shelves you bought it on.
