Acidity is a tricky element of coffee. Some people crave it, and others do everything they can to avoid it.

This can be due to either flavor preference or because of a sensitive stomach.

Personally, I think a piquant acidity balances a sweet cup coffee, but if that’s not your style I don’t hold any grudges.

In this article, I’ll explain exactly what you should be looking for if you want to find the best low acid coffee beans that still offer flavor.

Is coffee acidic?

Coffee, in general, is an acidic beverage with a Ph level of around 5. However, soda and orange scores around Ph 3, so comparatively it’s not that acidic.

Green coffee beans contain acids from nature’s side. The most desirable ones are citric and malic acids. These compounds make coffee taste like lime and apples as well as a whole range of stone fruits and berries.

But coffee beans also contain something known as chlorogenic acid, which isn’t known to be tasty. It often gives off a flavor and mouthfeel which can be described as ‘unripe banana’. Not pleasant, at all.

When coffee is roasted, all the acids gradually disappear. Then the Maillard reaction and caramelization occurs. In regular cooking, we call this effect ‘browning.’

A good rule of thumb is that coffee becomes sweeter and less acidic the longer you roast it – up to a certain degree, of course.

How to find the best non acidic coffee beans

There are actually some robust rules of thumbs you can use when shopping for coffee.

A higher amount of acid (or sourness) is often found in lighter roasts. In that sense, it’s a good idea to go for a darker roast. However, you shouldn’t go for an espresso beans, as the sweetness will be subdued and replaced with some bitterness.

Instead, you should look for what is known as a ‘full city’ roast. This is a roast profile that can be described as ‘the darker spectrum of a medium roast.

Countries with low acid coffee beans

Okay, but now you had enough of my specialty coffee rant, and just want some recommendations for low acid beans? I hear you.

Some countries are also known for producing exactly this kind of flavor profile. This has to do with the altitude the coffee is grown at.

Brazil is an excellent place to look for a coffee that has body and roundness. Again, Brazilian coffee beans usually aren’t favorites among hardcore coffee snobs, but if you’re looking for something clean, sweet and acid free, it’s a good bet.

Indonesia is another country that is often recommended for coffee drinkers who want a different experience. Coffee from Sumatra is one of the least acidic ones – usually it’s earthy and has more body than and mouthfeel compared to African or Central American coffees. Remember, that you also want to make sure that the roast is medium to dark if you’re going to ensure a non-acidic experience.

Pro-tip: Avoid coffee from Kenya, Ethiopia, Rwanda, and Guatemala as it’s almost always light roasted and very fruity.

Counter Culture Big Trouble

Go Deeper: Sourness, bitterness and Acidity

As mentioned before, low acid doesn’t always mean tasty. In the world of specialty coffee, acidity is also used to describe the brighter flavors that can be found in expensive, high-altitude coffees.

Real coffee lovers actually distinguish between

  • sourness
  • bitterness
  • acidity

The two first ones are negative traits, while the last one is an essential part of a quality coffee.

A perfect cup, according to true coffee snobs, is one that combines sweetness and acidity.

Think of it as a hamburger. You don’t only want the sweet or umami flavors from the bun and the beef patty – you also crave the acidic and fresh flavors from pickles, tomato, and raw onion. It’s a more complete experience that way. That’s the way coffee geeks approach the cup.

It’s worth remembering that your idea of what constitutes acidity is not the same as a pro coffee cupper’s view on the matter.

The reason that acidity might be undesirable in your cup of morning joe is that the coffee isn’t sweet in the first place, or because it’s actually sourness.
