What does it mean? Acid vs acidity

Before we get to coffee, here’s the definition of acid:

‘A substance with particular chemical properties including turning litmus red, neutralizing alkalis, and dissolving some metals; typically, a corrosive or sour-tasting liquid of this kind’, Google tells us.

In simpler terms, it means any substance that has a pH level of less than 7.

Coffee has a pH of around 5, which is actually less than a lot of juices, fizzy drinks and alcoholic drinks.

However, when we are talking about this substance in coffee, we aren’t referring to the pH level.

The presence of certain acids in our favourite drink creates varying flavours, and for a lot of people it is a desirable characteristic.

But first, here’s a few example products, which you can choose if you really do want to buy low acid coffee.

Is decaf coffee acidic?

Although caffeinated coffee may not have a higher concentration than decaffeinated does, decaf coffee beans may be better for those who are sensitive to acid content.

This is because caffeine can cause your stomach to generate more acid. So, for those who struggle with symptoms of GERD (Gastroesophageal reflux disease), decaf may be a healthier option for your body.

Decaf that goes through a mountain water process is best for low acidity as it removes the caffeine thoroughly and safely, without the use of harsh chemicals.

Where does coffee acidity come from?

There are two main groups found in coffee; chlorogenic and quinic.

Chlorogenic acids are antioxidants. Large concentrations are found in green beans, but as you roast the beans the levels diminish. Benefits of this group include weight loss, reduced blood pressure, improved mood and a smaller risk of developing diseases such as diabetes and cancer.

Quinic acids are developed as the beans are being roasted. They are responsible for the flavours in coffee, such as a ‘bright’ or ‘mellow’ acidity.

Is coffee acidity good or bad?

We can split this question into two:

1. Is it good for flavour?
2. Is it good for health?

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
• Sweet
• Fruity
• Sharp
• 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.

Can I remove the acid from my coffee without altering the taste?

There are a few ways which some claim will lower the concentration in your cup. Although, they have not been scientifically proven to reduce it.

1. Use a coarser grind to avoid over extraction. As there is a small surface area, less acid may be extracted from the grounds.
2. Use a cold brew method as this is less likely to bring out the acids compared to using hot water.
3. Add milk to your drink as it will help neutralise it.
4. Some claim adding egg shells or baking soda to your drink will reduce high concentrations, however we wouldn’t recommend this as it may affect the taste and may not be pleasant.

Low acidity coffee is the best way to avoid high concentrations, as no flavour is sacrificed, and you still get to enjoy high-quality, delicious blends.

How to complement the taste of coffee

Of course coffee is known for its rich, bold flavours and vibrant acidity That’s partly why it pairs exceptionally well with cake. Firstly, the coffee’s acidity complements the sweetness of the cake, creating a harmonious balance of flavours. The coffee’s boldness provides a delightful contrast to the cake’s texture, enhancing the overall sensory experience.

Furthermore, the complex notes in coffee, such as fruity, nutty, or chocolaty undertones, can mirror or complement the cake’s ingredients. Whether it’s a moist chocolate cake, creamy Vanilla cake or a fruity tart, acidic coffee’s versatility enhances the dessert’s flavours, making it a perfect pairing for any cake lover.
