How long does it take for coffee to wear off?

In the average adult, the half-life of caffeine is about 5-6 hours. This means that once take a dose of caffeine, you’ll break down about half of that caffeine after 5-6 hours.

Can you drink day old coffee?

We don’t recommend drinking day-old coffee, especially if it has gone rancid and has accumulated an unpleasant smell and/or taste. Brewed coffee also has a tendency to accumulate molds especially when kept outside the fridge. Do not drink day-old coffee if it has milk mixed in it, unless you kept it in the fridge.

Does coffee expire or go bad?

The good news: No, coffee doesn’t really go bad in the way that bread grows mold or a banana slowly rots on your counter top. And drinking coffee made from old beans won’t make you sick, even if the expiration date has passed. (We can’t vouch for the taste, though).

Is coffee still good after 4 years?

If taste is your concern, your best bet is to store coffee in an airtight container somewhere cool, dry, and dark. Stored this way, ground coffee can be used for a few months past its expiration date, whole bean for up to nine months, and instant coffee for up to twenty years.
