Cold Brew Process Yields Low Acid Coffee
Both bean type and roast type can play a major role in the acidity of the coffee but how you make your coffee also makes a difference. Cold brew coffee, and the process to make it, significantly reduces the volume of organic compounds such as caffeine and acids, compared to hot-water brewing.
A tradeoff of drinking cold brew coffee in lieu of hot coffee that takes only minutes to brew is it takes around 12 to 24 hours to make. But the result is compelling. Industry research has determined that slow-steeped cold brew coffee has 70 percent lower acid levels without sacrificing taste. Understand the difference between iced coffee and cold brew. Iced coffee is made by simply cooling down hot brewed coffee and is not a process that will result in low acid coffee.

Premium Roasters Use The Drum Roasting Process
In the drum roasting process, the green coffee is heated to only 200°C for 20 – 30 minutes. During this process, a roasting master with experience must be present, who determines whether the roasting process requires a different temperature or more time based on the smell and also specific noises.He knows the exact roasting profile for each variety and thus gets the best out of each bean. This is the only way to develop the very special characteristics of a single origin. Only then does the roast master blend the separately roasted coffees into a perfect blend.With these roasters, the quality of the coffee is in the foreground. This requires more time and effort, but the result is tasty!
Decaf Coffee Vs Caffeinated Coffee
Low acid coffee is available in decaf. Switching to decaf coffee may reduce heartburn, acid reflux, and GERD.3 Caffeine causes the LES to relax allowing stomach acid to reflux into the esophagus. Decaf coffee, however, still contains some caffeine. Those with digestive disorders should avoid drinking decaf coffee in excess.
Is decaf coffee less acidic than regular coffee?
No, decaf coffee is not necessarily less acidic than regular coffee. Coffee acidity depends on the coffee bean, roast, processing method, and the brewing method used. The primary benefit of decaf coffee for reducing acid reflux symptoms is the lack of caffeine. Caffeine relaxes the LES increasing the likelihood of acid reflux.

Water Temperature Is Important
The optimal extraction temperature for coffee is between 195 and 205 degrees Fahrenheit. Water, on the other hand, boils up to 212 degrees.
If you allow the water to boil completely, and use it when the temperature is too high, you end up quickly extracting the flavours. This will include the oils which are hugely responsible for coffees acidity.
To avoid this, go ahead and use a thermometer to measure waters temperature before adding the coffee grounds. In case you do not have a thermometer, giving the water 30 seconds to cool down will lower the temperatures to optimum levels.
While at it, keep your extraction time between 4 to 5 minutes.
Feel Good About Your Caffeine Fix
Brewing your own coffee at home is taking control of what you are putting into your body. Not only are you saving money by avoiding coffee house prices, but you are also gaining the luxury of choosing exactly which beans you want to put in your beverage. Go ahead and pick out one that leans toward the fruity side, perhaps a Colombian bean with its unique spicy finish or an Ethiopian bean that is floral in aroma.

What Is Coffee’s Ph Level
Coffee does indeed have a pH level, but this is not a useful measure of flavor. It would vary depending on brewing method and roast level, but not significantly.
Most coffees have a pH around 4.5.
A “low acid coffee” falls around 4.7 and a “high acid coffee” falls around 4.3. While this may not seem like a big difference, the pH scale operates on a logarithm , so a 0.4 difference can actually be substantial.
For comparison, apple juice lands at 3.8 .
Acidity as a flavor descriptor does not refer to the pH level of the coffee. It also shouldn’t be confused with the character of sourness .
This ambiguity is nothing more than a failure of the coffee industry to properly name its measures.
A high acidity is described as bright while a low acid coffee may be described as smooth, but if it is too low it will be considered unexciting and boring. A total lack of acidity may also result in a “flat” coffee.
Black coffee generally lands around a pH of 4.5 and milk has a pH of 6.5 . This means that adding milk to coffee makes it slightly less acidic by way of dilution.
Ph And The Brewing Process
Another thing that can affect the perceived acidity of a coffee is the brewing process.
Most baristas will agree that the faster a coffee is brewed, whether it be a shot of espresso or a pour over, the more acidic it will taste.
This is because acidity is one of the first things to be extracted when brewing coffee.
On the flip side, the longer a coffee is brewed, the less acidic it will taste. This is because the coffee brewed for longer will contain more bitterness and more sweetness, both of which help balance out the acidity.
While the brewing process wont alter the actual pH level of the coffee beans, it will change the way that acidity is perceived.
For example, cold brew pretty much always tastes less acidic than the same coffee brewed as a pour over.
But these two drinks will have a very similar pH level. So whats the deal? It turns out that pH isnt the only thing that decides how acidic a coffee tastes. With lower levels of what is known as titratable acidity, cold brew tastes far less acidic to most people.
Likewise, adding milk to coffee doesnt do too much to increase the pH either. Milk has a level of around 6.5, meaning that it too is acidic. However, when we add milk to coffee, we are diluting it, reducing the coffees perceived acidity.

Are There Health Risks To Drinking Coffee
Many people opt for low acid coffee because the acid in regular coffee causes some discomfort and low acid coffee options allow them to enjoy coffee without these side effects.
However, its important to understand that for some people, its actually a very serious issue. There are many conditions that, when severe enough in a person, can be dangerously affected by too much acid in coffee:
- Acid reflux
- Gastric ulcers
- Irritable bowel syndrome
If youve been officially diagnosed with any of these, its often recommended that you avoid coffee altogether. Although low acid coffee can be an option for those who suffer from these conditions, its important that you heed the instructions of medical professionals above all else.
How Different Roasts Have Low Acid Profiles
Casual observance of the roasting process proves that one of the best ways to lower the acidic level of any coffee regardless of region or natural acidity is to roast the beans darker.
Dark roasts are quite popular and making coffee with them is a great way to ensure you are getting lower acidity. Even still sometimes you want a lighter roast and sticking to the aforementioned regions can help.
If you are looking for the lowest acidity levels possible in your coffee then definitely stick to the regions mentioned above and err to the side of the dark french or Italian roasts. The darker the higher the pH levels and the more palatable the coffee will be to your stomach. Sure, you could go for a branded low-acid coffee but you will get better results sticking with naturally low acidic levels in the beans.

Is Coffee Acidity Good Or Bad
We can split this question into two:
Firstly, flavour. It is down to personal preference, but a bold acidity is usually a desirable characteristic for the flavour of your brew. Different substances and concentrations can give flavours such as:
- Citrus
- Wine/grape
- Clean/crisp
Secondly, health. The only issues it may cause are for your stomach. If you have a sensitive stomach or suffer with acid reflux, then it may be a concern for you.
For those with sensitive stomachs, in large quantities it could damage stomach lining or cause you to produce excess acid, which can cause acid reflux.
If you are concerned about this or have symptoms of GERD, then low acid products are the perfect way to continue enjoying coffee.
Choose A Darker Roast
Lighter roasts naturally contain more acids in the beans as the roasting process is fairly quick. As a general rule, the darker the roast of the bean, the less acid it contains. This is due to two main factors.
Firstly, the longer the beans are roasted, the more they are processed and the chemical compounds are affected. Simply put, the acids burn away during a longer roast cycle.
Another factor that makes these beans less likely to upset your system is the reduction of caffeine in these beans. Darker roast beans generally contain less caffeine than light and medium roasts. This results in less acid being produced by your stomach and less chance of you feeling unwell after consuming coffee.

Why Is Coffee Acidic
There are many reasons why your coffee may taste acidic and cause adverse reactions in your digestive system. Coffee naturally contains acid, and certain brew techniques or post-brew habits may increase the acidity in your cup.
Firstly, acidity and alkalinity are measured on the pH scale with a pH of seven being classed as neutral. Anything above this is seen as alkaline, while the figures below are known as acidic. Coffee beans measure somewhere around a pH value of five. This means that coffee can easily upset you if you are sensitive to acid.
Luckily, you dont have to give up on the delicious brew just yet. There are several ways to reduce the acid levels in your cup, such as choosing a better bean, changing your brewing method, and being mindful of some post-brewing habits.
The acid in coffee is released at different rates through different brewing methods, and if your coffee is unusually acidic, it could be a result of under-extracted coffee. This is presented as a sour cup of coffee as the acid is what gives coffee that distinct sharp taste.
While usually the acid is welcomed in a cup of coffee, it should be balanced correctly to ensure it offers the sweeter tasting acids while reducing the sour acids. This brings us to the idea that the acidic taste in coffee does not come from one type of acid.
Best Temperature For Drinking
When it comes to drinking a cup of coffee, the best temperature is a matter of preference. Warm, room temperature water will not extract as much acid from the beans, resulting in a beverage with a smoother flavor. However, if you prefer your drink to be hot or cold, simply let it cool for a few minutes after brewing to avoid burning your tongue on the first sip.

Acidity Comparison Between Cold Brew Coffee And Hot Brew Coffee
For this comparison, we scoured the web for scientific papers that made the most sense.
The paper titled Acidity and Antioxidant Activity of Cold Brew Coffee covers the topic in the best way possible.
Since antioxidant levels are outside the scope of this topic, lets stick to the acidity levels discussed in this paper.
| Coffees Region | |
| 4.95±0.04 | 5.08±0.04 |
According to the table , it is clear that the CQA levels in hot brew coffee are a lot higher than cold brew coffee while there isnt a huge difference in the pH levels.
What does this mean?
The pH value is simply the quantification of deprotonated acid molecules in a sample.
The pH value of both cold brew coffee and hot brew coffee is between the range of 4.85 and 5.13. When considering the pH value, you can say that there is not a big difference when it comes to acidity between these two brewing methods.
But thats not where the story ends.
You can figure out the acidity of a drink outside the pH scale. Thats why we have included the CQA levels in the table.
CQA stands for Caffeoylquinic acids. The total CQA in the table is the sum of 3-CQA, 4-CQA, and 5-CQA levels in the sample. This should give you a better idea of the total acids present in the coffee.
When you consider the CQA levels, you can see that cold brew coffee is a lot less acidic when compared to hot brew coffee. Why is that?

Is Coffee Acidity Bad For The Health
According to research, the acid present in coffee is a combination of almost 34 natural acids also found in oranges, apple and vinegar. Due to the presence of antioxidants, minerals and vitamins, coffee bean is inherently acidic.
However, each of us has a different body reaction to the natural acids when we drink coffee. Some people feel discomfort. Others experience a burning sensation similar to heartburn and acid reflux. Some people with weakened or thinning tooth enamel tend to develop tooth decay when drinking coffee.
While these issues occur, it is not a direct correlation to coffee. Coffee does not cause or result to acid reflux or tooth decay. People with existing conditions often have a negative body reaction to coffee.

Which Coffee Has The Least Acidity
Coffee with milk has the lowest acidity. Coffee has a pH value of about 4.5, milk about 6.6. Depending on the amount of milk added, the pH value increases accordingly. The higher the pH of a liquid, the more basic or less acidic it is.The Arabica and Robusta coffee varieties have different acidity levels. However, this difference is very small when you consider the influence that roasting has on the acidity: whether a coffee is low in acidity depends much more on the type of roasting than on the coffee bean variety. During roasting, the acidity increases first, so that mildly roasted varieties have a higher acidity. If the roasting process takes longer, the coffee then loses acidity, up to 50% of the original content. In this way, the roaster can determine the level of acidity himself.
The roasting process is decisive for the acidity of the coffee bean.
The darker the beans are roasted, the less acid they contain!
Does Instant Coffee Have Less Acid Than Regular Coffee
There is no difference between instant coffee or fresh ground coffee in terms of acidity. What you need to find is the correct bean, region, and roast to find a low acid instant coffee. Find a dark roast Arabica from a low elevation region like Brazil or Central America to get the best flavor and lowest acidity in coffee in your final cup.
The only difference you will find in acidity is through the brewing process. Since instant coffee is not brewed in the same way as fresh grounds, you cannot take the extra steps to lower the acidity in coffee as mentioned above during the brewing process. Your best bet is to find instant coffee made from low acid coffee beans that result in a cup of low acid coffee.

What Are The Ph Levels In Instant Coffee
Just like with all other coffee types, the acidity and pH level of instant coffee will depend on several factors such as the processing method, origins climate and roasting times. Coffee that is grown at higher elevations and colder temperatures will ripen slower, which will develop more complex flavors. It will tend to be more acidic and aromatic than coffees that were grown in warmer climates.
The coffee roasting time will also affect the chemical balance of the beans and their flavors. While the pH levels of dark and light coffee roasts might be the same, very dark roasts and cheap coffee beans are also notorious for being overly acidic.
It is important to note that all coffees and instant coffees have some acidity, which cant be removed however, some brands neutralize the acid levels with added potassium. Adding potassium to instant coffee is as if you put an antacid tablet in your cup of joe.
At Waka Coffee, we chose not to include any additives in our instant coffees so we dont neutralize the natural acid levels of our coffees. Both our Indian instant coffee and Colombian instant coffee have pH levels of 4-5. Our decaffeinated Colombian instant coffee has pH levels of 4.5-4.5.
