Carefully selected coffee beans may last for 2 years. But a cup of brewed coffee-in terms of taste- is said to be best for the first hour it was served. Traditional coffee drinkers wouldn’t care to dispute that claim about the brew because you may even agree that the statement is true.
I had been using a 12-ounce coffee maker and I never got to brew more than 16 ounces for 4 spoonfuls of finely ground arabica coffee. Someone had told me that the finely ground coffee powder yields stronger brew than the coarse variety when the brew is continuously heated for up to 12 hours. But I did not bother to try it because I had dropped the practice of drinking reheated brew; the taste of reheated coffee isn’t like the taste of the original fresh brew.
It didn’t occur to me that brewed coffee isn’t meant to be prepared in bulk until I came across the cute 2-ounce coffee maker at a hotel in New York. It confirmed my theory that brewed coffee is unlike wine that becomes more desirable as it gets older. I realized why the customized 2-ounce coffee maker existed. You cannot simply throw away without regret the leftover precious brew.
Coffee making tips
I got curious when someone suggested that I look into several websites or coffee-making tips; the websites didn’t yield anything new or remarkable, but most of what they say is similar to what I found other also said. I found from other sites the following interesting quips:
So, does brewed coffee go bad?
- Brewed coffee’s longevity depends upon whom you ask about it.
- Brewed coffee is good only up to the point where its distinct taste ends.
- Consume brewed coffee while it’s hot. The brew becomes either safe or harmful to consume after it has gone cold.
- Flavor and safety are the common parameters being used to measure the longevity of brewed coffee.
- It’s better to brew small amounts of coffee-good for 1 to 2 hours. If you want coffee later in the day, brew anew.
- Is it safe to drink day-old coffee? You could refrigerate the brew for up to 4 days. You may serve it hot or cold.
- If you brew coffee with cold water, it may last for 2 weeks in the fridge.
- How long can coffee sit out with milk? Unadulterated brewed coffee lasts longer than when milk, creamer or sugar is added to it. Coffee with pasteurized milk last longer than coffee with unpasteurized milk.
- Brewed coffee using coffee powder derived from selected coffee beans tastes better and lasts longer.
- You do not get sick for imbibing stale brewed coffee; you get sick because of the harmful organisms that contaminate it.
- If you drink brewed coffee for what it is meant to be- regardless of what science may say- drink your coffee within 20 minutes from the time it was brewed.
- The validated Ig-Nobel prize-winning 5-minute rule applies to coffee. Coffee is an astringent, a lot of growth may take place in it for a while, but contamination eventually happens.
- The longevity of brewed coffee is notably influenced by the quality of water, the roasted beans’ quality, the brewing procedure, and the storage conditions.
- There are people who really like to drink cold-brewed coffee. Cold-brewed coffee is being served along with liquor in some bars.
- It’s best to refrigerate brewed coffee in airtight sealed bottle containers.
- It’s also possible to preserve brewed coffee as ice cubes, but ice cubes couldn’t convert into a full-fledged coffee.
- Remove from your fridge decaying items that may contaminate the coffee brew.
- Pathogenic bacteria thrives and grows more rapidly in temperatures above 40 degrees Fahrenheit. Your brewed coffee is susceptible to these kinds of bacteria. Remember that refrigeration only slows down the growth of bacteria.
- Cooking generally kills microorganisms. But repeatedly reheating cold coffee makes its taste turn sour.
- Any coffee left at the counter for 12 hours becomes breeding ground for bacteria.
- A scientific study has yet to conclusively confirm how long brewed coffee may last.
Your taste bud
Brewed coffee is unlike wine that attains greater value as it grows old. Brewed coffee deteriorates as time goes by. Hence, enterprising coffee parlor owners had been trying ways to preserve the brew. It seems the persistent ones had stumbled on converting liquid coffee into ice cubes as a cheap and practical way to extend the useful life of brewed coffee. Preserving brewed coffee as ice cube could be simpler in many ways than storing brewed coffee in a tightly closed container in the fridge. But the ice cubes couldn’t convert into full-fledged coffee, but these could serve as iced-coffee candy.
Should there be a scientific experiment to study brewed coffee’s longevity, I hope the scientists will also determine if the nutritional value of the brew should be a factor to consider.
