Making the best Jura coffee comes down to three factors: 1. Choosing the best coffee beans for Jura machines 2. Perfectly grinding the beans to the correct level of coarseness 3. Using the proper water temperature There are thousands of coffee bean options available in the market, so make sure to experiment and find something that works well for you. There is no correct answer here, only your preferences to guide you. Secondly, there is the fineness of the grind. How coarse or finely a coffee is ground has an enormous impact on the final brew. With a finer grind, more of the coffee's surface area is exposed to water, and a greater proportion of flavors leech into the water, and the stronger your coffee is in terms of taste. However, this may also mean that a lot more bitterness enters your coffee as well. Thus there is no correct answer here either, and you can play around with the settings until you find one that works well. Finally, the water temperature is an individual preference that depends from person to person. You may enjoy lower or higher temperatures than those you are currently brewing coffee. Water temperature often goes ignored as many people do not think it affects the flavor of the coffee. Even if this was true, it still significantly affects the drinking experience and how much you end up enjoying your beverage.
