My coffee tastes too acidic, what can I do to balance it out?
Here are some of the steps you can take to tweak your coffee brewing process:

* you might be under extracting, try grinding you coffee beans finer
* another way to increase your extraction rate is to use less coffee grinds or more water
* if you’re doing the pour-over method, blooming the coffee first might help removing the co2, improving the extraction 
* you might want to try a darker roast, these have more nutty and chocolaty flavors that might better fit your taste
