Let's explore the possible causes of this sour taste. A common reason is to extract coffee during the brewing process. This happens when you are making coffee and there is not enough flavor to extract from the coffee grounds. The longer the coffee, the more sugar is extracted from the coffee grounds, and the sweeter the coffee will be. However, if you take too long, you will taste bitter (over-extraction). The second reason for sour taste is more taste preference. If you are used to deeper baking, you may think that the lighter baked fruit is sour. I even heard a coffee drinker describe fruity Ethiopian barbecue as someone who poured orange juice into his coffee. If sour taste is a matter of taste preference, I suggest you either stick to dark baking or slowly change from dark roasting to medium roasting, and then Colombian / Brazilian coffee becomes Ethiopian coffee. This is a great way to relax your taste buds and adapt them to a variety of coffee tastes. You don't have to plunge into the abyss. If you think insufficient extraction is the reason, here is a quick list of the reasons for insufficient extraction during the extraction process.

The reason of insufficient extraction by extraction method

-pour water? Try medium size grinding powder. If you grind it too fine, it will make it impossible to grind down.

-espresso or inflatable skirt? Try a finer grinding size. Even medium-sized grinding can lead to insufficient extraction.
