Buttermilk is not a good choice for coffee. Its high acidity can cause curdling when mixed with hot coffee, resulting in a sour and unpleasant taste. While it is nutritious and low in fat, most people prefer alternatives like whole milk, oat milk, or cream for a smoother and richer flavor.
Also, you can add milk powder to coffee.
However, some people prefer buttermilk in coffee, so it is a personal preference of an individual.
I will discuss which type of milk is better in coffee, why buttermilk isn’t a good option, and what will happen if we add buttermilk to coffee.
What is buttermilk?
Buttermilk is a fermented dairy product with a slightly sour taste and thick texture, similar to yogurt.
Traditionally, it was the liquid left after churning butter. Today, it is made by adding lactic acid bacteria to milk, which gives it:
- A tangy flavor
- Creamy consistency
- Probiotic benefits
Buttermilk doesn’t have butter in it. Traditionally, butter is the product obtained from the fat in milk.
But nowadays, butter is a dairy product caused naturally by bacteria and lactic. Butter is thick and similar to sour cream. Also, buttermilk is pretty identical to Greek yogurt.
What Happens When You Add Buttermilk to Coffee?
Combining buttermilk with coffee typically results in an unpleasant taste experience.
Here’s why:
- Coffee is naturally acidic
- Buttermilk is even more acidic
- Heat + acid = curdling
If you want buttermilk in your coffee, hold, and think again. You may get a bad experience while doing this. This option is not sweet or creamy as what you usually want for coffee.
Why Buttermilk Curdles in Coffee
When buttermilk meets hot coffee:
- The proteins coagulate
- The drink separates into lumps
- The texture becomes unpleasant
Result: Sour, curdled, and unappetizing coffee
Explain scientifically
Heat + acid = protein coagulation, which leads to curdling
Coffee = acidic (pH 5)
Buttermilk = more acidic (pH 4.5)
Also, make coffee with powdered sugar.
Pros and Cons of Buttermilk in Coffee

Does Buttermilk Work Better in Iced Coffee?
Yes, it provides slightly better results, but it is still not ideal.
In cold drinks:

- The tangy flavor remains strong
It may work if you enjoy slightly sour beverages, but it’s still an acquired taste.
