Many friends who don't like acidic coffee have had this experience: they order based on online recommendations, only to brew a cup with a fruity sour taste that ruins their mood. What exactly determines whether coffee is sour or bitter? How can you choose beans to avoid sourness? This article explains it all at once.
The acidity and bitterness of coffee mainly depend on these factors
The roast level is key to influencing sourness. The lighter the roast, the more acidity the coffee beans retain, and the more pronounced the floral and fruity aromas; the darker the roast, the more the acidic compounds are broken down, and the bitterness and body increase accordingly. So if you're afraid of sourness, prioritize medium-dark or dark roast beans, and you basically won't go wrong.
Origin and processing method also have an impact. Beans from different regions naturally have different flavors—some are bright and tangy, some are mild and mellow; processing methods like natural and washed also affect the final acidity. Generally speaking, beans from low-altitude regions (such as Brazil and Indonesia) are naturally lower in acidity, while beans from high-altitude regions (such as Ethiopia and Kenya) are brighter in acidity.
Simply put: if you want low acidity, just go for the combination of "dark roast plus a mellow-type origin" and you're set.

Two small tips for friends who are afraid of acidity
First, pay more attention to roast level information when buying beans. If you see words like "light roast" or "medium-light roast," and the flavor description includes "citrus," "berry," or "floral," the acidity will generally be more pronounced, so avoid those first if you're afraid of sourness.
Second, if you want to transition from "slightly acidic" to "not acidic," you can start with beans like medium-dark roasted Yunnan Typica, and once you've adjusted, try low-acidity options like Mandheling and Brazil Queen's Estate.
Once you understand what you like and how to choose beans, drinking coffee will become more and more enjoyable.
