Have you ever had a cup of coffee that is just off? It’s more common than you think. Sour or soapy (yes soapy) flavored coffee has something to do with how you are extracting your coffee. Let's address the problem of soapy or sour tasting coffee and give you some ideas of how to to these unwelcome flavors happen and ways to resolve it. Soapy
Sour coffee normally happens when you are under-extracting when brewing the coffee. This can be due to the incorrect grind. The coffee may be to coarse and make a finer grind will help reduce that. Next I would look at the water temperature. Rising the temperature will increase how much is extracted from the beans. Too hot will make it bitter or a burnt taste. Too cool will result in soapy or sour coffee. You can control this by adding a thermometer to your kettle or getting a water boiler/warmer. Rule of thumb is to set the water aside for about 30 seconds before pouring . The third way to can adjust is brewing time. If you brew the coffee longer, you will have a longer extraction time. If your grounds are finer, the extraction time is longer. If this is off and you have a less time brewing, you can get soapy or sour taste. Last but not least is the ratio of coffee to water. If you are adding to much or too little water, it can come out sour in the end.
With practicing these minor adjustments on brewing your coffee correctly, you'll be brewing your coffee on the daily in no time. Enjoying the pleasant flavors of the blend you purchased.
