Some people believe that starting with cold water is the best way to make coffee. Others think that it makes the coffee taste bad and there are better ways to produce coffee. But the question remains. Why do coffee makers suggest starting the process with cold water? The cold brew method is a different way of making coffee. This article will explain how coffee makers utilize cold water to provide a hot and tasty cup of coffee.
How Does Water Affect the Coffee Taste?
Most people would agree that the combination of hot water and coffee brings out a strong taste, especially when compared to iced coffee. This is because hot water has a very high surface tension which causes it to be viscous.
However, water affects the taste of the coffee differently. Temperature affects the extraction of the flavor. The hotter the water, the more flavors it releases. The downside of using hot water is its tendency to burn the coffee grind and cause a bitter taste at times.
Making Coffee With Cold Water
By heating water to its boiling point, you’ll get a better extraction since the water has more capacity to dissolve the coffee oils. Water that is too cold won’t dissolve these oils and they’ll sit at the bottom of your cup, creating a layer of sludge. So why recommend starting with cold water?
Hot Water Is Less Acidic
Boiling water lowers the pH of the coffee by a significant margin. The lower pH reacts with the oils in the beverage, releasing acids and giving it a sharp taste. Cold water neutralizes the acidity and gives a cup of sweet-tasting coffee.
Different Temperatures of Water
The variants in water temperature give different results for the end product. For example, boiling water gives a different outcome than hot water. If the water is too hot, the level of acidity will increase in the mixture. However, keeping the water cold would reduce the acidity and produce a flavorless coffee.
Cold water coffee has a lower extraction rate than coffee made in hot water. However, this is not the case with iced coffee, which has a higher extraction rate than its counterpart. If you want your coffee to taste flavorful and fresh, consider using cold water.
Temperature Affects Tasting
Different water temperatures have different effects on the taste. This also applies to coffee brews in general. The warmer the beverage, the more intense its flavor will be. Cool temperature coffee would be a refreshing drink when it’s hot outside but tastes worse when the atmosphere is chilly.
Is It Better To Use Cold Or Hot Water?
Both cold and hot water have their pros and cons. Hot water is capable of extracting more flavor from your coffee beans than cold water. On the other hand, adding ice to the coffee means that it’s already diluted with melted water. The advantage of cold water is producing a less acidic coffee and it doesn’t burn the coffee grind.
How Does the Water Temperature Affect Coffee Taste?
If you make your coffee with cold water, the oils in the coffee beans will dissolve slowly. As a result, these oils won’t be evenly distributed in the cup. Instead, they’re going to sit and concentrate at the top of the cup. On the contrary, these oils dissolve very quickly in hot water and their extraction is also even. That’s why coffee in hot water taste better and eliminates any off-flavors that might be present.
The Optimum Temperature For Extraction
The suitable temperature for aroma and flavor extraction is 185°F. This temperature is a bit higher than the coffee brewed in cold water. If your looking for a mild tasting coffee, then cold water temperature is a better option. Never make coffee in boiling water and only use it once the temperature has dropped below the optimal level.
Finding the Right Temperature
Start With Cold Water
It’s better to use a digital thermometer to find the exact temperature for a delectable cup of coffee. So if you take 180°F water for the grounds, the taste of the beverage would be bitter. However, using water with a temperature of 190°F would provide a low-tasting coffee. Instead, figure out a middle ground. Start at 180°F and use more hot water as needed.
Preparing Coffee With Cold Water
1. Use a larger coffee to water ratio for making coffee. Since the cold water isn’t going to extract the coffee oils from the beans, this process must be carried out in different ways. By increasing the amount of coffee, you’ll get more flavor from each cup.
2. Grind the beans before brewing them. Grounded coffee beans will release more flavor and aroma during the brewing process than finely grounded beans. As a result, it’s best to grind beans in a medium-coarse size before brewing them.
3. Fill the coffee maker with enough water to cover 41% of the grounds in a single layer. This is one of the most critical steps required to prepare cold-brew coffee.
4. When the grounds are steeped, you can add sugar, cream or fruit and then pour it over a hot cup of coffee. It’s important to remember that the consistency will change between cups of coffee once the ice has melted. The temperature of the drink will drop below 90 degrees.
5. While it’s tempting to add cream and sugar right into the coffee, both food ingredients can affect the texture of the coffee. If the main goal is to get a drink that produces a warm effect, then bubbles should not be left in the mixture. As a result, before you pour in any flavorings, take a spoon or whisk and give the bubbles a good stir.
Which One Is Good for Coffee, Bottled or Tap Water?
Bottled water has a distinct taste. Most of these are treated with different amounts of minerals, salts and other chemicals to give the water flavor. Tap water and bottled water vary in terms of these chemicals depending on the location and area.
It’s best to use a filter in the faucet or reverse-osmosis filter when using tap water. A reverse-osmosis filter will remove particles, bacteria and other unwanted material from the cup. On the other hand, it doesn’t change the taste of the water, making it an excellent choice for cold-brewing coffee.
How Long Does It Take To Make a Cold Brew?
When you’re making cold brew, you should allow the coffee to steep for about 12 hours. This period allows for the extraction of all flavors from the coffee grounds and adds them into the cup.
Common Mistakes While Preparing Coffee
1) Using Excessive Hot Water
A common mistake that cold brew makers make is using too much hot water. If you do this, the coffee will grow weak and bland. Instead, add enough water to cover the grounds completely.
2) Over-Extracting Or Under Preparing
Another common mistake for first-time cold-brew aficionados involves an insufficient extraction or preparation of grounds. If coffee is made with a limited amount of water, it will taste weak and bitter. If you use too much water, it will be sweet and less flavorsome.
3) Not Adding Enough Flavor
When you’re making coffee with cold water, you’ll need to put in more coffee to get the same amount of flavor. According to many experts, this is the main advantage that cold brewing has over hot brewing. If you’re making your coffee with hot water, it’s easy to add sugar and cream.
4) Pouring Hot Coffee Quickly
If you put hot coffee in a glass or mug and pour it quickly, the drink produced will taste weak. To develop a strong flavor and aroma, let the coffee sit for some time.
5) Pouring Too Much Milk
When you’re making a cold brew with hot water, adding too much milk can be dangerous. If you’re hesitant to add milk, then you should use cream. Milk tends to curdle when it is left at room temperature for a long time.
6) Forgetting To Stir
The last common mistake that first-time cold brew drinkers make is forgetting to stir their grounds after brewing them, leading to over-extracted or under-extracted coffee. As a result, it’s essential to ensure that all coffee grounds are immersed entirely in water.
How Long Does It Take To Make a Steaming Hot Cup of Coffee?
Although steeping coffee grounds for 5-10 minutes is usually enough, you should allow them to steep for 12 hours if you want a flavorsome cup of coffee. The coffee will become much more intense in aroma and stronger in taste.
The cold brew coffee method is growing in popularity and is great for those who suffer from acid influx. It is an optimum drink for coffee enthusiasts who want a milder and smoother taste. Starting with cold water, it has various benefits and advantages. It helps to maintain the freshness of the coffee and preserves all the flavors.
This method of coffee making is great for individuals with sensitive stomachs. It doesn’t contain caffeine which is a common cause of acidity. Hope this article was a good read for you and provided valuable information. Take care!
