You can make it hot or cold for a silky, comfortable, and delicious freshly roasted coffee experience. However, we understand that you probably want to know all the facts. That’s why we’ve broken it all down below!

Key Takeaways

  • In the world of coffee, the question, “is cold brew coffee less acidic?” is frequently posed. The answer can be found in the brewing nuances.
  • Primarily, the cold brew coffee preparation method distinctly involves steeping coffee grounds in cold water, often for an extended period.
  • Interestingly, the types of coffee beans selected can influence the overall acidity of the brew, with some beans naturally having lower acidic profiles.
  • The brew time of cold brew coffee also can alter the acidic content extracted; longer brew times typically mellow out the sharpness.
  • Additionally, temperature fluctuations during brewing have a direct impact on acidity extraction, with colder environments reducing acidic compound leaching.
  • Not to forget, even the water type for brewing might play a role in determining the final pH level of the coffee, especially if the water has specific mineral contents.
  • Thus, while cold brew is generally seen as less acidic, several variables determine its final acidity.

is cold brew coffee less acidic? Everything you need to know!

The simple answer is: it depends. According to studies from Thomas Jefferson University, the cold method often has a slightly higher pH level  thebrew hot method. However, there are many exceptions to this.

Different types of “Caffeine seeds” can have different levels of acidity. If you prprefer theot method, there are plenty of great options too. Tartness is tricky when making a cold infusion, and the method you use to make your drinks is important too!

When that is made by slowly steeping it in cold water, it definitely feels silkier and is less irritating when consumed. This is related to inflammatory effects in the body, temperature, and tartness.

  • Cold-brew’s pH ranges from 5.10 to 6+, while espresso has a pH of 4.9 to 6. So they are generally in the same pH range.
  • The beans can also have a pH of up to 4.8, depending on the beans used, how they are processed, how roasted they are, and the acidity of the water used for making them.

However, I am here to tell you that concentrations of total titratable acids may adjust. 

The thing is, extracting coarsely ground coffee in fresh, cold water for 24 hours can help balance tartness and potentially distribute lipids more evenly. Also, as a rule of thumb, heat causes inflammation, while cold tends to reduce it. That’s why you ice inflamed muscles but use heat to combat nerve pain.

Types of acids and how they affect coffee taste

It can be helpful to understand which type is less zesty and how the zesty flavor acts on cold and hot brew coffee. Here you’ll find all the types of zesty compounds in a cup of coffee and how they affect the flavor profile of the beans.

  • Additionally, higher concentrations of total titratable zesty compounds affect whether you can taste the zesty flavor of the coffee.
  • Therefore, even if coffee has high zesty characteristics, you may not be able to taste it in certain situations. Ergo, regular iced coffee brewed using the hot brew method and then poured over ice is just as zesty as any hot-brewing coffee.
  • Alternatively, hot coffee made from our dark-roasted Arabica coffee beans is far less zesty than any Starbucks cold-brew.
  • Here are the five main types of caffeic and zesty compounds and how they affect their taste.
Types of acids and how they affect coffee taste

Citric acid

Citric acid has a fruity and spicy taste. Think lemons and oranges. Due to the humid climate and slow growth of trees, Latin American beans are known to contain high levels of citrus tartness.

The citrus tartness is also removed during roasting. A medium roast contains only about 50 percent of the original acid concentration of citrus tartness.

A dark roast contains even less citrus tartness and therefore has a silkier, less acidic flavor than a hot roast.

While Latin American coffees are often known for having a fruitier flavor due to citrus tartness, Kenyan coffees are believed to contain less citrus tartness. Even when they’re green and unroasted, these beans are super soft.

Acetic acid

Acetic acid is also affected by the degree of roasting. The darker you roast the beans, the less acetic acid there is. In low concentrations, acetic acid gives coffee a clean, pleasantly sweet taste.

It also helps create the fermented beverage flavors that so many people love in cask-aged. Acetic acid is affected by cultivation methods and soil types.

Quinic acid

This acid gives the coffee a slightly astringent taste. People who don’t like the dryness of ingredients taste quinic acid.

However, quinic acid goes well with a gin and tonic! Brewed that sits on the boiler for too long develops that Chinese taste. That’s why fresh coffee always tastes better! Our drinks are always delivered freshly roasted on the day the order is received.

So if you want the freshest, least bitter beans, you’ve come to the right place.

Malic acid

Next is malic tartness. It is found in fruits such as green apples and has a tangy taste. It also leaves a lingering taste on the tongue.

This tartness is produced in the plant itself, and roasting does not have much of an effect on it. If you want to avoid this tanginess, look for coffees from Africa.

We have some delicious ones, like our Ethiopian Yirgacheffe! Alternatively, the Panamanian type is known for its distinct apple flavor. It is sometimes described as imparting notes of apple or pear.

Phosphoric acid

Phosphoric acid has no taste. However, it does affect your taste buds. It leaves a sharp taste and a tingling sensation on the tongue.

High amounts of phosphoric acid should be avoided. Instead, a balanced drink is best. Too little phosphoric acid, and your beverage will be boring. Too much, and it has a hard bite. Coffee that is freshly picked at the peak of its ripeness is ideal!

Don’t worry; all our coffee would come from there. Check out our single-origin beers to get the ideal phosphorus levels straight from the source!

Chlorogenic acid or CQA

This type of acid leaves a bitter taste on the tongue. It is most often found in Robusta beans. So if you don’t like that lingering bitterness, skip Starbucks.

Instead of a cold beverage from Starbucks, make your own beverage with Arabica beans! Arabica beans undoubtedly have far less CQA. Good news for you: Almost all of our coffees use pure Arabica beans in different varieties from regions around the world!

4 burning truths about making low-acid coffee

The facts about low-acid coffee can be elusive. Some people simply avoid drinking their favorite beverage because they are trying to reduce the acidity of their diet, avoid heartburn, or suffer from gastritis or other gastrointestinal or gastroesophageal diseases (GERD), such as acid reflux.

The taste of your drink is heavily influenced by the acids naturally occurring in the beans. So how can you reap the benefits of an enjoyable caffeine experience, including caffeine, while minimizing your body’s exposure to the acids naturally occurring in the beans?

There are four main factors that affect coffee acid levels:

  • coffee bean variety
  • the roasting type of the bean
  • The following process followed to prepare the coffee
  • water quality
  • The good news for coffee lovers is that you can control these factors, resulting in a friendlier, less acidic coffee experience.
4 burning truths about making low-acid coffee

Influence of the type of bean on the acidity of the coffee

Coffee is grown all over the world. The correlation to wine is that the terrain or soil characteristics of the country and the climate in which the plants grow have an impact on the quality and taste.

Some types of beans are better choices for low-tartness coffee. For coffee drinkers trying to minimize tartness exposure due to stomach irritation or other reasons, there are two categories of options to consider: treated and unintentional.

Treated coffee is just as it sounds – the beans are treated through a mechanical process to change the tartness of the beans. Alternatively, some beans are naturally low in tartness, and these types of beans fall into the “unintentional” category.

Examples of countries that grow low-tartness beans include Brazil, Sumatra, and Nicaragua (email our roaster to check if we have Nicaraguan coffee in stock). Although the origin of the bean is not the only important factor in producing acid-free coffee, it is a good starting point.

Influence of the type of roasting on the tartness of the coffee

In addition to the type of bean, roasting is another important factor in enjoying low-tartness coffee. The difference between light, medium, and dark roasted beans simply depends on how long the beans spend in the roaster. The actual tartness and pH of the coffee will be very similar regardless (assuming the bean type is the same across all roasts).

However, industry research suggests that there is a chemical called N-methylpyridium that is produced during roasting and reduces the ability of stomach cells to release hydrochloric tartness.

Therefore, opting for a dark roast coffee combined with a bean variety with lower tartness is a good option to enjoy coffee and counteract increasing tartness sensitivity.

The cold brew process produces coffee with low acidity

Both the type of bean and the roast can play a big role in the tartness of the coffee, but the way you prepare your coffee also makes a difference.

The least tart coffee preparation method is to make cold coffee. The manufacturing process significantly reduces the amount of organic coffee beans for cold extraction compounds such as caffeine and acids compared to hot water brewing.

One downside to drinking cold coffee instead of hot coffee, which only takes a few minutes to make, is that it takes about 12 to 24 hours to prepare. But the result is convincing. Industry research has found that cold-brewed and slow-brewed teas have 70 percent less tartness without sacrificing flavor.

Understand the difference between iced coffee and cold brew. Iced coffee is made by simply chilling drip coffee brewed, which is not a process that results in low tartness. You can email our roaster to order Grumpy Goat Cold Brew in 16-ounce bottles, half gallon bottles, or full gallon bottles.

Test your water for the acidity of coffee. Water is the main ingredient in your coffee. If you use tap water to make your coffee, be aware that the pH of that water can affect the tartness of your coffee.

Many municipal water supply systems inject chemicals into their systems to keep water contamination to a minimum. These treatments can affect the tartness of your water.

Home water filtration systems are one way to avoid this challenge. Additionally, a digital pH meter can be used to determine the alkalinity or tartness of the water you use to make your coffee.

Sometimes we pay so much attention to the beans, roasting, and brewing that we overlook the importance of water – an underestimated factor in the overall taste of your coffee.

The burning truth about enjoying low-acid coffee

With conflicting information online, researching the facts about acid-free coffee can be frustrating. Focus on the four main factors that determine low-acid coffee—bean type, roast type, making method, and water. When you take control of these four factors, you can start enjoying the benefits of coffee again.
