When you order your iced coffee, do you ever think why they are so bitter? Surprisingly, the answer is not just in the amount of coffee that goes into your drink. The bitterness comes from the way that your coffee is brewed.
In brewing, coffee is boiling in water and then cooling it down to a very cold temperature. This process creates two chemicals: acid and caffeine. Acids break down flavors in coffee, while caffeine gives it that bitter taste. In the following, we will disclose all the findings that make iced coffee bitter.
Reasons, Why Iced Coffee Is Bitter?
When coffee is brewed, the hot water causes the oils and acids from the coffee beans to come out. These oils and acids are what give coffee its distinct flavor. Iced coffee, however, is brewed with cold water. This doesn’t give the same opportunity for the flavors to develop, which can make iced coffee taste bitter. Additionally, when hot water is poured over ice cubes, it can create a watered down drink.
Coffee Bean Quality
Different coffee beans have different levels of bitterness. This is because the flavor compounds in the bean interact with one another in different ways. Some of these interactions produce flavors that are perceived as bitterness, while others don’t. The best quality beans will have less bitterness and a richer flavor.
An article published in The Atlantic details how coffee bitterness can vary depending on the quality of the beans. The study looked at 11 coffees from around the world and found that while all the coffees had a bitterness rating below 5 on a scale of 1 to 10, the ratings differed significantly depending on where they were from. For example, Ethiopian coffees had a rating of 3, while Brazilian coffees had a rating of 8.
Over-Extracted Coffee Beans
With over-extracted coffee beans, you’re likely to experience more bitterness in iced coffee. This is because over-extraction causes the coffee beans to be released too many chlorogenic acids and caffeine that are not balanced with the sweetness of the ice cream or other ingredients. These chemicals can create a bitter taste in iced coffee.
The Brewing Method Used
Although most people believe that iced coffee is made by adding cold water to hot coffee, the truth is that the brewing method used is the reason for its bitterness. Iced coffee is typically made with hot coffee, ice, and milk, but the way that these ingredients are mixed can actually create a bitter taste. When the hot coffee is poured over cold ice, it causes a rapid decrease in temperature, which crystallizes any dissolved gas in the liquid.
Brewing iced coffee using a cold brew method results in a bitterness that is not experienced with hot coffee. The water used for brewing is at a lower temperature, which causes the coffee grounds to extract more flavor and caffeine than when brewing with hot water. This increased bitterness is caused by the chemical compounds called tannins that are present in coffee beans. Tannins interact with water molecules to form complexes that can bind to taste receptors in the human mouth.
The Roast Level Of The Coffee Beans
Roasting the coffee beans creates chemicals that change the way they taste when cooled, resulting in an Iced Coffee with less bitterness. However, not all coffees are roasted to create this flavor. Some, like Folgers, have a moderate roast level, resulting in a less intense flavor.
The higher the roast level, the more bitter the resulting iced coffee will be. Roasts that are darker than medium tend to be the most bitter, while lighter roasts produce less bitterness.
Dilute with Ice
When you order an iced coffee at a restaurant, you might be surprised to learn that the drink is often diluted with ice before it’s served. This dilution makes the coffee taste bitter because cold water reacts with the coffee’s acidity to create a sour flavor.
If you’d like to enjoy a refreshing iced coffee without the bitterness, try making your own by using fresh brewed coffee and cold water.
Poor Storage and Chilling Practices
Poor storage and chilling practices can lead to coffee bitterness. Researchers from the University of Alabama at Birmingham studied how stored iced coffee affects bitterness. They found that cold temperatures cause the compounds responsible for bitterness to form faster and in greater amounts. These findings could help improve the quality of iced coffee products.
