  2. I’ll often leave black coffee in a thermos or closed container overnight, If I know I’ll be pressed for time in the morning. A quick 30 seconds or so in the microwave and it’s drinkable, granted not quite as good as fresh ground and brewed but it’s coffee.

  3. I do not know about others, but I do keep black coffee overnight at room temperature about 70 F or 21 C, heat it next morning in the microwave, and use it.
    I have been doing for years, and writing this answer/article, obviously, it is okay to do so.
    Lately, I put it in the refrigerator just in case and use it the next morning. I just love coffee, sometimes I wake up very early in the morning and start my day. And do not want to disturb anyone by making too much fuss, I warm up coffee with any fuss as quietly as I can and get out or start my paperwork.
    Some times I work very late and coffee is just like a fuel to me, I brew a pot and keep going, and whatever is left I use it the next day.
    I found out leftover when refrigerated it tastes a bit better than keep at room temperature.
    I have not done any scientific study on the leftover coffee such as do some microbiological testing or other chemical tests.
    These observations are based on my sensory evaluations and my own use.
    I hope it helps.

  4. Yes. In fact it can be left on the counter for several days. Eventually it will be colonized by a mold – you’ll see little floating islands of greenish white in the pot. But until then you’re good to go.
    In summer I cold steep coffee (grounds in the water, stir, and leave out for about 8–12 hrs.) filter off the grounds the next day, and drink from that jug, for the day. Sometimes in a heat wave we refrigerate the filtered coffee. Or add ice.
    If you do this, grind the beans fairly coarse.

  5. Yes, black coffee can be left out overnight.
    However, it is important to note that coffee will continue to oxidize and deteriorate even after it is brewed, so it is not advisable to leave coffee out for too long.
    If you plan on drinking coffee the next day, it is best to refrigerate it or store it in a sealed container at room temperature. This will help prevent the coffee from going bad and tasting stale.

  6. Almost all the coffee sellers would recommend you to drink fresh brewed coffee instead of storing it till the other day, generally speaking coffee won’t go bad too soon if you store it in the refrigerator, 3-4 days is Okay, while under room temperature you’d better dump it out after 12-24 hours.
