One question that often arises with French press brewing is whether it is okay to leave coffee in the press after it is brewed. In this article, we’ll explore the answer to this question.
Brewing Coffee In A French Press
If you love coffee, you’ve probably heard about the French press. It’s a great way to make delicious coffee at home without any fancy equipment.
But can you leave coffee in a French press? Let’s explore the steps involved in brewing coffee in a French press and how long you can leave coffee in it.
The Steps To Brewing Coffee In A French Press
Brewing coffee in a French press is a simple process. Here are the steps to follow:
- Start by boiling water in a kettle.
- While the water boils, add coarsely ground coffee to the French press. A good rule of thumb is to follow a 1:15 coffee-to-water ratio.
- Once the water is heated, pour just enough water slowly to cover the coffee, give a gentle stir and let it sit for 30 seconds. It is called blooming, which allows carbon-di-oxide to escape from the coffee beans resulting in a better-tasting cup.
- After 30 seconds pour the rest of the water (not the boiled water, use 195~205 °F water)
- Let the coffee steep for four minutes.
- After the steeping time is up, use the plunger to separate the coffee grounds from the liquid.
- Pour the coffee into your mug and enjoy!
Coffee In A French Press: What Happens When You Leave It?
Coffee in a French press is an excellent way to start the day. It is easy to make and provides an incredible taste to coffee lovers.
But can leave the coffee in a French press for an extended period? Let’s explore the effects of leaving coffee in a French press.
Bitterness Is Intensified
If you leave coffee in a French press for an extended period, it continues to brew, and the bitterness increases. As a result, the coffee taste becomes unpleasantly acidic and strong.
Oxidation Takes Place
Oxidation is a process in which coffee comes into contact with air, altering its taste and aroma. Over-brewed coffee in a French press is more likely to undergo oxidation, resulting in a stale flavor.
Contamination By Microbes
Leaving the coffee in a French press for an extended period may lead to microbial contamination, as microorganisms can quickly grow in damp environments.
You should avoid consuming coffee that has been left in a French press for more than four hours.
Leaving the coffee in a French press for too long leads to an unpleasant aroma. The stale odor may cover up the typical coffee aroma, making it hard to enjoy the coffee experience.
Leaving the coffee in a French press for an extended period ruins the perfect coffee taste. The fermentation process intensifies, bitterness increases, and the coffee aroma becomes stale, contaminating the coffee with microorganisms.
It is best to pour the coffee into a thermal carafe after brewing it and avoid leaving it in a French press.
