Can You Put Buttermilk In Coffee? – BaristaHQ

If you're someone that enjoys drinking coffee, there's nothing wrong with experimenting with various flavors to make your coffee more enjoyable to drink.

While syrups and other coffee flavor enhancers are typically the best way to improve the taste of your coffee, what about buttermilk in coffee?  

In this guide, we’ll talk about whether or not you can put buttermilk in coffee, and if it will affect the overall taste of your coffee.  

Traditional buttermilk refers to the liquid that remains after whole milk has been churned into butter. Nowadays, however, buttermilk is a fermented dairy product that mainly consists of water, lactose, and the milk protein casein. It is also pasteurized, homogenized, and contains lactic-acid producing bacteria. 

Buttermilk is typically used for baking and is a common ingredient in biscuits, muffins, and pancakes. It can also be used in batter for fried foods or in soups and salad dressings. Buttermilk comes with plenty of nutrients which include protein, calcium, and riboflavin.

Is Buttermilk In Coffee A Good Idea? 

While you might think that buttermilk could be a great idea in coffee, the sour taste of buttermilk doesn't work well with coffee and often ruins its overall taste. Since buttermilk has lactic-acid producing bacteria in it, adding buttermilk to coffee is on par with adding plain Greek yogurt into your coffee. 

Both coffee and buttermilk are also relatively acidic; hence when you combine them together, you'll end up getting a sour and bitter coffee that's not palatable at all. In addition, buttermilk also has the potential to curdle your coffee. If you’ve got some leftover buttermilk that you’d like to use, there are plenty of other better ways to use it.
