If you’re a person who loves coffee, you may think of using it twice to brew another cup of coffee the next day. Now the question is, can you use coffee grounds twice?
You can use coffee beans twice to brew another cup of coffee, but the taste you will get will not be the same due to the presence of bitter-tasting compounds in the second brew.
Do you get the coffee with the same taste and flavor as the second brew? No.
Coffee extraction is the method that occurs during the preparation of the coffee. Naturally occurring desirable compounds are dissolved during the process of extraction. The coffee solubles are lipids, fruit acids, caffeine, melanoidins, carbohydrates, and plant fiber.
What happens when you brew your first cup of coffee?
When you pour water on coffee beans, the extraction starts, and the coffee’s soluble compounds ( fruit acids, sucrose, sugars, and coffee oils) starts dissolving in the water. The aim is to dissolve 30% of the compounds in the coffee, if you brew it for a longer time, bitter solids from coffee will start dissolving.
Most of the taste and flavor producing solids are dissolved during the extraction of the first cup. So if you are using the coffee grounds the second time, you will get bitter-tasting tannins in your cup.
Also, when coffee comes in contact with water, it produces carbon dioxide.
Compounds released during the extraction
During the extraction, solids that get dissolved in a coffee cup depend a lot on the extraction method. The most common methods to extract Coffee grounds are the drip method, french press, espresso.
As long as you use creamer and other flavoring agents to make the coffee, you will not feel the taste change.
It is best to avoid using coffee grounds for the second cup.
Cons of using coffee grounds the second time
When you brew the coffee the first time, most of the solids responsible for fruity flavors and sweetness dissolve with the water.
If you are using a paper filter, only dissolvable solids will pass to the cup.
Coffee extracted with other French press, Turkish fabric, espresso will allow even non-dissolving solids in the cup. This is the reason why coffee tastes bitter at the end.
If you try to reuse the coffee grounds to make one more coffee, it may taste unpleasant.
Due to moisture and the temperature, used coffee grounds are a perfect place for bacteria and molds.
